Embodiment 1

[0052] According to an embodiment of the present invention, an automatic financial collection method based on voice question and answer is provided, see figure 1 , including the following steps:

[0053] S101: Carry out endpoint detection based on the Gaussian mixture model to the input sound signal, and identify the speech signal from the sound signal;

[0054] S102: The keyword-based detection method is combined with the automatic speech recognition method to perform speech recognition on the speech signal;

[0055] S103: Jump between sessions with the user according to the global problem state machine and according to the recognized voice.

[0056] In the automatic financial collection method based on voice question and answer in the embodiment of the present invention, the present invention proposes a Gaussian mixture model method in combination with the actual business scene. This method makes up for the shortcomings of the double threshold method and the deep learning m...

Embodiment 2

[0068] According to another embodiment of the present invention, an automatic financial collection device based on voice question and answer is provided, see Image 6 ,include:

[0069] An endpoint detection unit 201, configured to perform endpoint detection based on a Gaussian mixture model on an input sound signal, and identify a speech signal from the sound signal;

[0070] The voice recognition unit 202 is used for performing voice recognition on the voice signal based on the keyword detection method in combination with the automatic voice recognition method;

[0071] The conversation jumping unit 203 is configured to jump between conversations with the user according to the global question state machine and according to the recognized voice.

[0072] In the automatic financial collection device based on voice question and answer in the embodiment of the present invention, the present invention proposes a Gaussian mixture model method in combination with the actual busine...

Abstract

The invention relates to the field of financial collection, in particular to an automatic financial collection method and an automatic financial collection device based on voice question answering. According to the method and the device, the method comprises the steps of carrying out endpoint detection based on a Gaussian mixture model on an input acoustical signal, recognizing a voice signal fromthe acoustical signal, combining a keyword-based detection method with an automatic voice recognition method to carry out voice recognition on the voice signal, and carrying out skipping between sessions with a user according to a global problem state machine and recognized voice. According to the method, a Gaussian mixture model method is provided in combination with a service actual scene, themethod overcomes the defects of a double-threshold method and a depth learning method, and the advantages of the double-threshold method and the depth learning method are considered to a large extent.In addition, in the invention, the detection method combined with keywords is adopted to detect the keywords in the answering voice of a client, the recognized result is combined with an original ASRsystem to judge, and the defect of inaccurate recognition of common mood words, idioms and the like of the original ASR method is overcome.

Description

technical field [0001] The invention relates to the field of financial collection, in particular, to an automatic financial collection method and device based on voice question and answer. Background technique [0002] At present, as the business of Internet companies increases, manual customer service can no longer meet the demand, and it is difficult to face the continuous growth of business. Especially for some Internet financial credit companies, the total number of non-performing credits continues to increase with business growth. For this reason, it is a practical solution to replace manual collection customer service with artificial intelligence robots, and artificial intelligence robot customer service can solve this problem well by using speech recognition and semantic logic analysis. [0003] The manual collection customer service in the traditional financial industry often has the following problems: 1. It is highly dependent on personnel and requires personnel wi...
