[0026] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] To facilitate those skilled in the art to better understand the embodiments of the present application, some technical terms or nouns involved in the embodiments of the present application are explained as follows:

[0029] LLM (Large Language Model): A large-scale natural language processing model based on deep learning technology. It is usually trained with massive corpus and can generate, understand, and process natural language text for tasks such as answering questions, generating content, and text analysis.

[0030] ASR (Automatic Speech Recognition): An intelligent speech processing system based on deep learning and signal processing technologies. It is usually trained with large amounts of speech data and can convert human speech into editable text content in real time. It is used for tasks such as speech transcription, voice command recognition, and real-time subtitle generation.

[0031] Among related technologies, while traditional voiceprint recognition technology can make a preliminary judgment on the speaker's identity based on voiceprint features, its recognition accuracy is greatly reduced in the context of customer complaint handling, when faced with complex situations such as physiological changes in the speaker and deliberate imitation of other people's voice tones. Related technologies that use automatic speech recognition (ASR) technology to transcribe complaint audio into text and then analyze the text's semantic features through methods based on keyword matching or simple machine learning models can initially identify keywords in the complaint text, but lack in-depth and accurate mining of the professional speech features of customer complaint experts. In particular, it is difficult to effectively identify and analyze complex semantic expressions, hidden complaint intentions, and diverse complaint logic. In other words, when handling customer complaint handling issues, related technologies, whether in the single voiceprint recognition or semantic analysis stages, have certain shortcomings and cannot meet the actual needs of enterprises for accurate and efficient identification of customer complaint handling behaviors.

[0032] In order to solve the above problems, the embodiments of the present application provide relevant solutions. First, a voiceprint vector library of customer service personnel is constructed by manual separation and voiceprint model calculation. The voiceprint vectors of customer service complaint experts are accurately extracted from the confirmed customer complaint audio to form a complaint expert voiceprint vector library. Then, automatic speech recognition technology and open source large language models are used to extract similar semantic expression sentences from the speech texts of customer complaint experts and manually verify them. A customer complaint speech feature system containing multiple main features and sub-features is constructed, and the corresponding model is trained. Finally, when identifying customer complaint behavior, voiceprint similarity calculation and semantic feature analysis are comprehensively used. Through specific rules and threshold judgments, efficient and accurate identification of customer complaint behavior is achieved, effectively solving the shortcomings of existing technologies in customer complaint identification and improving the efficiency of enterprises' supervision and processing capabilities of customer complaint behavior. The following is a detailed description.

[0033] According to an embodiment of the present application, an embodiment of a method for identifying abnormal complaint behavior is provided.

[0035] It should be noted that the one or more processors 102 and / or other data processing circuits described above may generally be referred to herein as "data processing circuitry". The data processing circuitry may be embodied in whole or in part as software, hardware, firmware, or any other combination thereof. In addition, the data processing circuitry may be a single independent processing module, or may be incorporated in whole or in part into any of the other components of the computer terminal 10 (or electronic device). As described in the embodiments of the present application, the data processing circuitry serves as a processor control (e.g., selection of a variable resistor terminal path connected to an interface).

[0036] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the abnormal complaint behavior identification method in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, implementing the above-mentioned abnormal complaint behavior identification method.

[0039] In the above operating environment, the embodiment of the present application provides a method for identifying abnormal complaint behavior. Figure 2 This is a schematic diagram of a method flow for identifying abnormal complaint behavior provided in an embodiment of the present application. Figure 2 As shown, the method includes the following steps:

[0040] Step S202: Acquire audio data to be recognized and determine a first audio segment of a target subject in the audio data to be recognized, wherein the audio data to be recognized is audio data containing a conversation between the target subject and a customer service representative;

[0041] Step S204: extracting a first voiceprint feature of the first audio clip and determining a similarity parameter between the first voiceprint feature and a second voiceprint feature, wherein the second voiceprint feature is a voiceprint feature of a full-time person who files complaints on behalf of customers and is stored in a complaint expert voiceprint database;

[0042] Step S206: extracting semantic and technical features of the customer communication text corresponding to the first audio clip, and determining behavioral parameters corresponding to the audio to be recognized based on the semantic and technical features, wherein the behavioral parameters are used to represent the degree of consistency between the semantic and technical features and the behavioral pattern of making complaints on behalf of the customer;

[0043] Step S208 : determining a recognition result corresponding to the audio data to be recognized based on the similarity parameter and the behavior parameter, wherein the recognition result is used to characterize whether the conversation corresponding to the audio data to be recognized contains behavior of making a complaint on behalf of the customer.

[0044] Through the above steps, by combining voiceprint recognition and semantic analysis to jointly identify abnormal behaviors such as customer complaints, the purpose of accurately identifying customer complaints is achieved, thereby solving the technical problem that the relevant technology has a low accuracy rate in identifying customer complaints.

[0045] The following further introduces the method for identifying abnormal complaint behavior in steps S202 to S208 of the embodiment of the present application.

[0046] First, the establishment process of the complaint expert voiceprint database and the training steps of the semantic analysis and recognition model used to analyze semantic speech are introduced in detail. Figure 3 As shown, in this embodiment of the application, the voiceprint features of valet complaint experts are accurately extracted by separating audio clips and calculating the mean of voiceprint vectors, and a valet complaint expert voiceprint database is established. Automatic speech recognition technology and open source large language models are used to extract the valet complaint expert's speech from the valet complaint expert text, and a valet complaint speech feature system is constructed. The model is trained using the valet complaint speech feature system. The specific steps for establishing the valet complaint expert voiceprint database are as follows.

[0047] In some embodiments of the present application, the method further includes the following steps: obtaining historical valet complaint audio data, and determining audio segments of valet complaint specialists in the historical valet complaint audio data, wherein the historical valet complaint audio data is historically identified audio data containing conversations between valet complaint specialists and customer service personnel; extracting a second voiceprint feature of the audio segment of the valet complaint specialists, and constructing a complaint expert voiceprint library based on the second voiceprint feature.

[0048] Specifically, we first obtain n real conversation audios of all customer service representatives in the enterprise with customers, separate the customer service and customer speech segments in the audio, use the voiceprint model to calculate the voiceprint vector of each customer service representative's n speech segments, and calculate the mean of the n voiceprint vectors as the voiceprint vector of the customer service representative to form the customer service representative voiceprint vector library DS sv ;

[0049] After that, the confirmed valet complaint audio file (i.e., historical valet complaint audio data) is obtained, and then the audio file is separated into audio segments of two people (e.g., the first subject and the second subject) speaking. The audio segments with the longest speaking time, voice1 and voice2, are respectively selected. That is, the longest audio segment among the multiple audio segments of the first subject and the second subject is obtained as the target audio segment. The calculation rule can be expressed as shown in the following formula:

[0050]

[0051] Calculate the voiceprint vectors vector1 and vector2 of voice1 and voice2 respectively, and compare vector1 and vector2 with the customer service voiceprint vector library DS sv Calculate the cosine similarity of the vectors in each and obtain their respective maximum similarity MaxS sv1 and MaxS sv2 .

[0052] If MaxS sv1 Greater than or equal to MaxS sv2 , then the first person (first object) is identified as a customer service representative, and the second person (second object) is identified as a customer complaint expert. sv1 Smaller than MaxS sv2 , the first person (first object) is identified as the customer service expert, and the second person (second object) is identified as the customer service representative; according to the above steps, all the confirmed customer service complaint audio files can be traversed to extract the voiceprint vectors of all confirmed customer service complaint experts, and the customer service complaint expert voiceprint vector library DS can be constructed. ev .

[0053] The following is a detailed introduction to the construction and training steps of the semantic analysis and recognition model.

[0054] On the one hand, we can use the audio clips of full-time complaint handling staff to build a database of professional complaint scripts. The specific steps are as follows.

[0055] In some embodiments of the present application, the method also includes: performing speech recognition on audio clips of the customer complaint specialist to obtain customer complaint text; determining similar semantic expression sentences between multiple customer complaint texts whose semantic similarity is less than a preset semantic similarity threshold, and storing the similar semantic expression sentences as professional complaint scripts in a script database.

[0056] Specifically, the automatic speech recognition technology can be used to extract the text of each audio clip (customer complaint text) from the audio clip of the customer complaint expert (customer complaint professional), and obtain the text set Text of all customer complaint experts. ts Then, based on the open source large language model and prompt word engineering, similar semantic expression sentences can be extracted from the collection of customer complaint texts. repeat , that is, to determine the similar semantic expression sentences between multiple customer complaint texts whose semantic similarity is less than the preset semantic similarity threshold, as shown in the following formula:

[0057] Text repat =LLM(Text ts ,prompt)

[0058] Where LLM is the open source large language model, prompt is the prompt word of the large language model;

[0059] In addition, you can also express similar semantics in sentences Text repeatManual verification is performed to remove sentences that are not related to complaints or business processing, such as greetings, insults, and intonation. Finally, the similar semantic expression texts after manual verification can be used as professional complaint scripts on behalf of customers and stored in the script database, as shown in the following formula:

[0060] DKTS text ={text1,text2,…,text n}

[0061] For example, suppose the text collection Text of the customer complaint expert ts For example, ["I am not satisfied with the refund of my order. If the issue is not resolved, I will file a complaint with the regulatory authorities.", "I am very dissatisfied with the service and request an immediate refund, otherwise we will take further action.", "If you do not handle it, we will demand full compensation.", "I am not satisfied with the processing speed. If the issue is not resolved, we will request termination of the contract."]; when inputting it into the large language model for extracting similar semantic expression sentences, the corresponding prompt words can be: [Extract sentences with similar semantic expressions from the following text set: {}, please list all similar semantic expression sentences in the form of a list:]; finally, the similar semantic expression sentence Text output by the large model is obtained. repat For [("If it is not resolved, I will complain to the regulatory authorities.", "Otherwise I will complain.")].

[0062] On the other hand, we can also use the preset feature dimensions of the complaint language to train the model through the semantic language features of the complaint text. The specific steps are as follows.

[0063] In some embodiments of the present application, the method also includes the following steps: according to a preset feature dimension, converting the customer complaint text into a vector form to obtain the semantic speech features corresponding to the customer complaint text, wherein the preset feature dimension includes multiple first-level features, each first-level feature corresponds to multiple second-level features, and the semantic speech features are used to characterize the number of times the semantic content corresponding to each second-level feature in the customer complaint text is mentioned, and the first-level features include at least one of the following: emotional expression, complaint logic, abnormal process, fuzzy identity, legal risk, and public opinion exposure; using the semantic speech features corresponding to the customer complaint text, the initial model is trained to obtain a semantic analysis and recognition model, wherein the semantic analysis and recognition model is used to predict the probability that the customer communication text is a customer complaint.

[0064] Specifically, in this embodiment, six main features of customer complaint speech consisting of emotional expression, complaint logic, abnormal process, ambiguous identity, legal risk, and public opinion exposure, as well as corresponding preset feature dimensions of sub-features of customer complaint speech can be constructed, as shown in the following table.

[0065]

[0066]

[0067] Then, we can use the large language model to judge the text from the valet complaint ts Determine whether the sub-customer complaint speech feature exists one by one, and record the number of times each sub-speech feature exists; ts Each text is represented as a feature vector, where each element represents the number of times a sub-feature appears, as shown in the following formula:

[0068] F i =[x i1 ,x i2 ,…,x in ]

[0069] Among them, F i Represents Text ts The feature vector of the i-th text in x ij is the number of times the j-th sub-feature appears in the i-th text;

[0070] For example, suppose the current valet complaint text is ts For example, if the sentence is ["I am dissatisfied with the order refund. If the issue is not resolved, I will file a complaint with the regulatory authorities."], the following prompt word is input into the large language model: [Please analyze the following complaint text to determine whether it contains the following sub-speech features: 1. Dissatisfaction; 2. Threatening language; 3. Sense of urgency; 4. Opening remarks; 5. Problem description; 6. Closing remarks; 7. Request for immediate action; 8. Bypassing normal communication channels; 9. Not the person (representing multiple customers); 10. Use of legal terms; 11. Exposure on social media / online forums; Please determine each one and count the number of occurrences.], then the semantic speech feature F corresponding to the customer complaint text is obtained. i is [1,1,1,0,1,0,0,1,0,0,0].

[0071] After obtaining the semantic speech features corresponding to the customer complaint text, the weight vector of the sub-features can be initialized as W = [w1, w2, ..., w n ], where the weight of each sub-feature is w j The initial value is set to 1. At the same time, set y i The actual label of the i-th text: 0.7 represents a valet complaint, 0 represents a normal complaint, and the objective function J is established. w And use this objective function to train the model.

[0072]

[0073] Where m is the number of samples.

[0074] This embodiment of the application utilizes an open-source large language model and prompt word engineering to extract professional valet complaint scripts. It also constructs a semantic feature system encompassing six main features and their sub-features: emotional expression, complaint logic, abnormal process, ambiguous identity, legal risk, and public opinion exposure. The large language model is used to determine the presence of sub-features and record their occurrence, representing the text as a feature vector. The model is then trained using gradient descent. This allows for in-depth and comprehensive analysis of the semantic features of valet complaint texts, accurately identifying various complex valet complaint scripts and intent. This effectively improves the accuracy of valet complaint identification and addresses the shortcomings of related technologies in mining semantic features of valet complaints.

[0075] After completing the establishment of the complaint expert voiceprint database and the training of the semantic analysis recognition model, the audio data to be recognized can be recognized. Specifically, Figure 4 As shown, in this embodiment of the present application, voiceprint similarity can be used for judgment. If the voiceprint similarity is lower than a threshold, semantic feature analysis is performed. A threshold is determined in the semantic feature analysis. If the threshold is exceeded, it is considered that a customer complaint has occurred, thereby achieving accurate identification of customer complaint behavior, as described below.

[0076] In some embodiments of the present application, determining the recognition result corresponding to the audio data to be identified based on the similarity parameter and the behavior parameter includes: when the similarity parameter between the first voiceprint feature and the second voiceprint feature is greater than the preset voiceprint similarity threshold, determining that the recognition result of the audio data to be identified is the existence of an act of making a complaint on behalf of a customer; when the similarity parameter is not greater than the preset voiceprint similarity threshold, judging whether the behavior parameter is greater than the preset behavior parameter threshold; when the behavior parameter is greater than the preset behavior parameter threshold, determining that the recognition result of the audio data to be identified is the existence of an act of making a complaint on behalf of a customer, and when the behavior parameter is not greater than the preset behavior parameter threshold, determining that the recognition result of the audio data to be identified is the absence of an act of making a complaint on behalf of a customer.

[0077] The following is a detailed introduction to the recognition process of the audio data to be recognized.

[0078] First, obtain the audio data to be identified, and determine the first audio segment of the target object in the audio data to be identified, extract the first voiceprint feature of the first audio segment, and determine the similarity parameter between the first voiceprint feature and the second voiceprint feature in the voiceprint library of the complaint expert. The specific steps are as follows.

[0079] In some embodiments of the present application, determining the first audio segment of the target object in the audio data to be identified includes: separating the audio segment of the first object and the audio segment of the second object in the audio data to be identified, and respectively obtaining the longest audio segment among multiple audio segments of the first object and the second object as the target audio segment; extracting a first voiceprint vector of the target audio segment corresponding to the first object and a second voiceprint vector of the target audio segment corresponding to the second object, and determining the highest similarity between the first voiceprint vector and each voiceprint vector in a voiceprint library of customer service personnel, and the highest similarity between the second voiceprint vector and each voiceprint vector in the voiceprint library of customer service personnel; if the highest similarity corresponding to the first voiceprint vector is greater than the highest similarity corresponding to the second voiceprint vector, corresponding to the first object as the customer service personnel, determining the second object as the target object, and determining the audio segment of the second object as the first audio segment; if the highest similarity corresponding to the second voiceprint vector is greater than the highest similarity corresponding to the first voiceprint vector, corresponding to the second object as the customer service personnel, determining the first object as the target object, and determining the audio segment of the first object as the first audio segment.

[0080] Specifically, the audio clips of the customer service staff and the target object (which may be a customer or a complaint expert) are separated from the audio data to be identified. The process steps for separating the first audio clip of the target object from the audio data to be identified are similar to the process steps for separating the audio clip of the complaint expert voiceprint database in the above process, and will not be repeated here. After that, the voiceprint features of the target object are extracted and compared with the complaint expert voiceprint database DS ev The off-chord similarity (i.e., similarity parameter) of the second voiceprint vector in the audio is calculated one by one. If it exceeds the threshold α, it is considered that the audio involves a valet complaint behavior. If it does not exceed the threshold α, subsequent semantic analysis processing is performed.

[0081] When the similarity parameter is not greater than the preset voiceprint similarity threshold α, the semantic speech features of the customer communication text corresponding to the first audio segment are extracted, and based on the semantic speech features, the behavioral parameters corresponding to the audio to be identified are determined. The specific steps are as follows.

[0082] In some embodiments of the present application, the behavioral parameters include: a first sub-parameter and a second sub-parameter; determining the behavioral parameters corresponding to the audio to be identified based on the semantic speech features includes: determining the speech status of the customer communication text corresponding to the first audio clip, and determining the first sub-parameter based on the speech status, wherein the speech status is used to characterize the frequency of the customer communication text containing professional complaint speech in the speech database, and the higher the frequency, the larger the corresponding first sub-parameter; according to the preset feature dimension, the customer communication text is converted into a vector form to obtain the semantic speech features corresponding to the customer communication text; using a semantic analysis and recognition model, the semantic speech features corresponding to the customer communication text are analyzed to obtain the second sub-parameter, wherein the second sub-parameter is used to characterize the probability that the customer communication text is a complaint on behalf of the customer; based on the first sub-parameter and the second sub-parameter, the behavioral parameters corresponding to the audio to be identified are determined.

[0083] Specifically, the target object's speech text is extracted from the first audio segment using automatic speech recognition technology. user (i.e., customer communication text), and then, the large model can be used to determine whether the customer communication text contains the complaint professional language in the language database, that is, to determine the language status of the customer communication text corresponding to the first audio clip, as shown in the following formula:

[0084] LLM(text user ,prompt,Text ts )

[0085] If it exists, assign β1=0.3, otherwise β1=0, where β1 is the first sub-parameter mentioned above.

[0086] Then, extract the customer communication text user The semantic feature vector w user Then, the semantic analysis and recognition model trained previously is used to analyze the semantic speech feature vector to obtain the prediction score β2 (i.e., the second sub-parameter mentioned above); finally, the sum of β1 and β2 is calculated to obtain the behavior parameter corresponding to the audio to be identified. If the behavior parameter is greater than the preset behavior parameter threshold ε, it is considered that there is a complaint behavior on behalf of the customer. In this embodiment, 0.3<ε≤1.

[0087] This application scheme significantly improves the accuracy and efficiency of recognition by combining voiceprint recognition and semantic analysis. Among them, voiceprint recognition can quickly screen out suspected full-time complainers, while semantic analysis deeply explores the subtle features of the complaint text. The two complement each other and effectively avoid the misjudgment that may be caused by a single technical means. In addition, by using large language models and prompt word engineering to extract professional speech, a comprehensive semantic speech feature system is constructed, which enables the system to recognize complex and changeable complaint logic and intentions. This method improves the company's ability to monitor abnormal complaint behavior, can more comprehensively and accurately identify customer complaint behavior, reduces the risk of misjudgment and missed judgment, and improves the company's supervision efficiency and handling capabilities for customer complaint behavior.
