[0062] It should be noted that the modifications of "one" and "plurality" mentioned in the present invention are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0063] Embodiment 1

[0064] Figure 1 The following is a flow chart of a voice control method provided in Embodiment 1 of the present invention. The method can be applied to application scenarios based on voice control, such as voice control of the operation of smart home appliances, video chat, voice-controlled game scenarios (such as "Dou Di Zhu"), etc. The voice control method can be executed by a voice control device, which can be implemented in the form of software and / or hardware and integrated into a smart terminal, such as a smart phone, a smart TV, etc.

[0065] like Figure 1 As shown, the voice control method provided in this embodiment includes the following steps:

[0066] Step 110: Receive voice information.

[0067] The voice information specifically refers to the voice acquired by the voice collection device of the smart terminal, and the voice can be any voice of any content and any object, such as shouting from the street, conversations between unrelated people, phone calls, and voice control commands spoken by relevant users to the smart terminal, etc. The voice collection device can be, for example, a microphone.

[0068] Since the voice acquired by the voice acquisition device of the smart terminal is relatively complex, it contains a lot of interference noise in the environment. The interference noise specifically refers to the sound that is not expected by the user, which leads to the problem of misrecognition, misoperation, low voice control accuracy and poor user experience in the smart terminal. For example, user Zhang San is playing the game "Dou Dizhu" on a smart phone. The card-playing action is realized based on voice control. When the teammate plays a card for the first time, a 4 is played. Zhang San's brother, who is watching next to him, can't help but want to play a prank and directly shouts "Wang Zha". Zhang San's brother's shouting "Wang Zha" is recognized by the mobile phone and the corresponding card-playing action is executed, which is not what user Zhang San expects. Not only does it cause user Zhang San to lose the game, but it also implicates teammates. For another example, user Zhang San is video chatting with his girlfriend. After seeing it, Zhang San's mother casually mutters "The makeup is too heavy". Zhang San does not want his girlfriend to hear this sentence, but because it has been acquired by the voice acquisition device of the mobile phone, it has been sent to Zhang San's girlfriend's mobile phone and heard by Zhang San's girlfriend.

[0069] The voice control method provided in this embodiment can effectively avoid the occurrence of the above-mentioned problems. Specifically, when receiving voice information, the corresponding timbre attributes are identified first, and whether to continue to perform subsequent control operations, such as semantic recognition, information sending and other control operations, is determined based on the identified timbre attributes.

[0070] Step 120: Perform timbre recognition based on the voice information to determine a target timbre attribute corresponding to the voice information.

[0071] Among them, human voice is emitted through vocal cords. The type of sound is physically determined by amplitude and frequency. The size of the sound (commonly known as volume) that people feel subjectively is determined by the "amplitude" and the distance between people and the sound source. The larger the amplitude, the louder the sound. The smaller the distance between people and the sound source, the louder the sound. Pitch refers to the height of the sound (treble, bass), which is determined by "frequency". The higher the frequency, the higher the pitch.

[0072] There is a saying that goes "You can tell a person by his voice", which refers to the timbre, also known as the sound quality. The wave generated by a vibration of an object is a complex wave. This waveform can be regarded as a superposition of sine waves of different frequencies and amplitudes. This complex wave determines the timbre of the sound. Sound has different characteristics due to the characteristics of different materials. The timbre itself is an abstract object, but the above complex waves are the intuitive expression of this abstract object. Different waveforms have different timbres. Different timbres can be distinguished by waveforms.

[0073] Exemplarily, performing timbre recognition based on the voice information to determine a target timbre attribute corresponding to the voice information includes:

[0074] Extracting the frequency and amplitude of the audio according to the voice information;

[0075] The target timbre attribute is identified based on the frequency and amplitude.

[0076] Step 130: Determine whether to respond to the voice information according to the target timbre attribute.

[0077] Specifically, determining whether to respond to the voice information according to the target timbre attribute includes:

[0078] Determining the similarity between the target timbre attribute and the preset timbre attribute;

[0079] If the similarity reaches a set threshold, it is determined to respond to the voice information.

[0080] The preset timbre attribute is a pre-stored timbre attribute that can be set by the user. For example, the pre-stored timbre attributes include three types, corresponding to Zhang San's voice, Zhang San's mother's voice, and Zhang San's father's voice. User Zhang San can set the preset timbre attribute to correspond to his own voice. At this time, the system only responds to Zhang San's voice information, but not other voices. In the above example scenario, Zhang San will not be disturbed by others when playing the game of "Dou Dizhu"; when chatting with his girlfriend, his girlfriend will not hear what others say except himself.

[0081] User Zhang San can also set the preset timbre attributes to correspond to his own voice, his mother's voice and his father's voice respectively. At this time, the system can respond to the voices of Zhang San, his mother and his father respectively. For example, in the voice control application of smart home appliances, the system can respond to the voice information of anyone in Zhang San's family.

[0082] Furthermore, in order to improve the recognition accuracy of the timbre attribute, when pre-storing the timbre attribute template, the user can be prompted to enter the specified voice multiple times, for example, prompting the user to enter the voice of a sentence, the voice of a word, the voice when the voice is loud, the voice when the voice is soft, the voice with a fast speech speed, and the voice with a slow speech speed, etc. By prompting the user to enter the specified voice multiple times, the user's timbre characteristics can be more comprehensively extracted, and the extracted timbre characteristics are used as the preset timbre attributes. When the voice information is received in real time, the timbre corresponding to the voice information is compared with the preset timbre attribute. If the similarity between the two reaches the set threshold, it is considered that the voice is made by the same person and can be responded to.

[0083] The set threshold may also be referred to as sensitivity. If the set threshold is set higher, the sensitivity is higher, the voice control accuracy of the system is higher, and it is less likely to be disturbed by noise.

[0084] Exemplarily, the responding to the voice information includes:

[0085] Performing semantic recognition on the voice information;

[0086] Execute corresponding control operations according to the semantic recognition results. The control operations include at least one of the following:

[0087] Sending the voice information to a target client;

[0088] Displaying target information corresponding to the semantic result;

[0089] Perform search tasks based on semantic recognition results.

[0090] For example, during a video call, only voice information that matches the preset timbre attributes is sent; in a smart home control application, only voice information that matches the preset timbre attributes is responded to. For example, if Zhang San says "Please turn on the TV" by voice, it is determined through the recognition and matching of the timbre attributes that the voice information "Please turn on the TV" can be responded to, and the control operation of "turn on the TV" is executed; if Zhang San's son says "Please turn on the TV" by voice, it is determined through the recognition and matching of the timbre attributes that no response is given to the voice information "Please turn on the TV", and the control operation of "turn on the TV" is not executed, that is, Zhang San's son cannot control the TV to turn on by voice.

[0091] The technical solution of this embodiment, when receiving voice information, performs timbre recognition based on the voice information, determines the corresponding target timbre attributes, matches the target timbre attributes with preset timbre attributes, and decides whether to respond to the voice information based on the matching results, thereby achieving the purpose of responding only to the voice of a specific user, improving the voice control accuracy, and enhancing the user experience.

[0092] Embodiment 2

[0093] Figure 2 This is a flow chart of a voice control method provided in Embodiment 2 of the present invention. Based on the above embodiment, this embodiment further optimizes the solution, specifically by adding step 140 "switching the preset timbre attribute". The benefit of this optimization is that the user can flexibly set the user object that can use the voice control function according to different application scenarios.

[0094] like Figure 2 As shown, the voice control method comprises the following steps:

[0095] Step 210: Receive voice information.

[0096] Step 220: Perform timbre recognition based on the voice information to determine a target timbre attribute corresponding to the voice information.

[0097] Step 230: Determine whether to respond to the voice information according to the target timbre attribute.

[0098] Step 240: Switch the preset timbre attribute.

[0099] Specifically, step 240 may occur at any time. This embodiment does not limit it to occur after step 230, and it may also occur before step 210. For example, Zhang San wants to have a video call with his girlfriend, and hopes that his girlfriend can only hear his voice and not the voices of others. Before the video call, Zhang San can switch the preset timbre attribute to his own timbre attribute. After the switch, the system only responds to Zhang San's voice, but not to other voices, which improves the voice control accuracy in specific scenarios and avoids the interference of noise on the control operation.

[0100] Exemplarily, the switching of the preset timbre attribute includes:

[0101] Determining the preset timbre attribute from at least two pre-stored candidate timbre attributes;

[0102] Different candidate timbre attributes correspond to the voices of different users.

[0103] The candidate timbre attributes are timbre attributes pre-entered into the system.

[0104] According to the technical solution of this embodiment, the user can switch and set the preset timbre attributes according to the specific voice control application scenario, so that the system only recognizes and responds to the voice of a specific person, thereby shielding the voices of other irrelevant people, thereby improving the voice control accuracy and user experience.

[0124] A determination unit, configured to determine the preset timbre attribute from at least two pre-stored candidate timbre attributes;
