Example 1
Fig. 1 is a flowchart of a voice control method according to an embodiment of the present invention. The method can be applied to application scenes controlled based on voice, such as voice control of intelligent household appliances, video chat, voice control of game scenes (such as 'fighting land owners') and the like. The voice control method can be executed by a voice control device, and the device can be realized in a form of software and/or hardware and integrated into a smart terminal, such as a smart phone, a smart television and the like.
As shown in fig. 1, the voice control method provided in this embodiment includes the following steps:
Step 110, receiving voice information.
The voice information specifically refers to a voice acquired by a voice acquisition device of the intelligent terminal, and the voice can be a voice of any content sent by any object, such as shouting from a street, conversation sound between irrelevant people, telephone sound, a voice control command which is spoken by a relevant user for the intelligent terminal, and the like. The speech acquisition device may be, for example, a microphone in particular.
Because the voice acquired by the voice acquisition equipment of the intelligent terminal is complex, interference noise in many environments can be contained, and the interference noise specifically refers to sound which is not expected by a user, the problems of misidentification, misoperation, low voice control precision and poor user experience of the intelligent terminal are caused. For example, when a user plays a game on a smart phone to play a game "fighting land", the playing action is realized based on a voice control mode, when teammates play the game for the first time, the player plays 4, watches the game aside, and can directly shout the game "Wang Zha", the "Wang Zha" shout by the player is identified and the corresponding playing action is executed by the mobile phone, which is not expected by the user, not only results in three-input games by the user, but also endangers teammates. For another example, the user chats with three girl friends in a video mode, the third mother sees blurt out talk endlessly a sentence of "make-up is too rich", and the third sentence of the third mother blurt out talk endlessly is not hoped to be heard by girl friends, but is acquired by the voice acquisition device of the mobile phone, so the user sends the voice to the third girl friends, and the third girl friends hear the voice.
The voice control method provided by the embodiment can effectively avoid the occurrence of the problems, particularly, when voice information is received, the corresponding tone attribute is preferentially identified, and whether the follow-up control operation, such as control operations of semantic identification, information transmission and the like, is continuously executed is determined according to the identified tone attribute.
And 120, performing tone recognition based on the voice information to determine a target tone attribute corresponding to the voice information.
Wherein, the sound of a person is emitted through the vocal cords, the kind of the sound is physically determined by the amplitude and the frequency, the person subjectively feels the size (commonly called the volume) of the sound, the larger the amplitude is, the larger the loudness is, the smaller the distance between the person and the sound source is, and the loudness is larger. The pitch refers to the high or low level of sound (high or low), and is determined by the "frequency", with higher frequencies being higher.
The popular language is cloud to "smell it to sound its person," i.e., timbre (Timbre), also known as sound. The wave generated by one vibration of an object is a complex wave, and the wave can be regarded as a superposition of sine waves with different frequencies and amplitudes. This complex wave determines the timbre of the sound. Sound has different properties due to the properties of different object materials, tone itself is an abstract object, but the complex wave is a visual representation of this abstract object. Different waveforms and different timbres. Different timbres can be distinguished by waveforms.
Illustratively, the performing tone color recognition based on the voice information to determine the target tone color attribute corresponding to the voice information includes:
extracting the frequency and amplitude of the audio according to the voice information;
The target timbre attribute is identified based on the frequency and amplitude.
And 130, determining whether to respond to the voice information according to the target tone color attribute.
Specifically, the determining whether to respond to the voice information according to the target tone attribute includes:
Determining the similarity between the target tone color attribute and a preset tone color attribute;
And if the similarity reaches a set threshold, determining to respond to the voice information.
The preset tone color attribute is a pre-stored tone color attribute, and may be set by a user, for example, the pre-stored tone color attribute includes three types, which respectively correspond to the sound of Zhang three, the sound of Zhang three mama and the sound of Zhang three dad. The user can set the sound corresponding to the preset tone color attribute, and the system only responds to the voice information of the user and does not respond to other voices at the moment; when the user is chatting with a girlfriend, the user cannot hear the user except himself or herself to say for other people.
The user can set that the preset tone color attribute corresponds to the sound of the user, the sound of the mother and the sound of the dad respectively, and the system can respond to the sound of the third user, the sound of the third mother and the sound of the dad respectively at the moment, for example, in the voice control application of the intelligent household appliance, the system can respond to the voice information of any person in Zhang Sanyi families.
Further, in order to improve the recognition accuracy of the tone color attribute, when the tone color attribute template is pre-stored, the user can be prompted to input the appointed voice for multiple times, for example, the user is prompted to input the voice of a sentence, the voice of a word, the voice of a loud voice, the voice of a fast voice, the voice of a slow voice and the like, by prompting the user to input the appointed voice for multiple times, the tone color feature of the user can be more comprehensively extracted, and the extracted tone color feature is used as the preset tone color attribute. When the voice information is received in real time, the tone corresponding to the voice information is compared with the preset tone attribute, and if the similarity of the tone attribute and the preset tone attribute reaches a set threshold value, the voice is considered to be the voice sent by the same person, and the voice can be responded.
The set threshold may also be referred to as sensitivity, and if the set threshold is set higher, the higher the sensitivity is, the higher the voice control accuracy of the system is, and the less likely it is to be disturbed by noise.
Illustratively, said responding to said voice information comprises:
carrying out semantic recognition on the voice information;
And executing corresponding control operation according to the semantic recognition result. The control operation includes at least one of:
Sending the voice information to a target client;
Displaying target information corresponding to the semantic result;
and executing the search task according to the semantic recognition result.
For example, in the process of video call, only the voice information matched with the preset tone attribute is sent, in the intelligent home control application, only the voice information matched with the preset tone attribute is responded, for example, the voice information of 'please turn on' is spoken by Zhang Sanhe, the television can be responded through the identification and the matching determination of the tone attribute, the control operation of 'please turn on' is executed, if the voice of the son of Zhang Sanhe is spoken by 'please turn on', the control operation of 'please turn on' is not executed, namely, the television cannot be controlled to turn on by Zhang Sanson.
According to the technical scheme, when voice information is received, tone recognition is performed based on the voice information, corresponding target tone attributes are determined, the target tone attributes are matched with preset tone attributes, whether the voice information is responded is determined according to a matching result, the purpose of responding only to voices of specific users is achieved, voice control precision is improved, and user experience is improved.
Example two
Fig. 2 is a flow chart of a voice control method according to a second embodiment of the present invention. On the basis of the above embodiment, the present embodiment further optimizes the scheme, specifically, adds the step 140 of "switching the preset tone attribute", so that the advantage 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.
As shown in fig. 2, the voice control method includes the steps of:
Step 210, receiving voice information.
Step 220, performing tone color recognition based on the voice information to determine a target tone color attribute corresponding to the voice information.
Step 230, determining whether to respond to the voice information according to the target tone color attribute.
Step 240, switching the preset tone attribute.
In particular, step 240 may occur at any time, and the present embodiment is not limited to occurring after step 230, but may also occur before step 210. For example, if Zhang Sanwang to make a video call with a girl friend, hope that the girl friend can only hear his own voice, but not hear the voice of other people, zhang Sanwang may switch the preset tone attribute to his own tone attribute before making the video call. After switching, the system only responds to the Zhang three voices, but does not respond to other voices, so that the voice control precision in a specific scene is improved, and the interference of noise on control operation is avoided.
Illustratively, said switching the preset tone color attribute includes:
determining the preset tone color attribute from at least two pre-stored candidate tone color attributes;
Different kinds of candidate timbre attributes correspond to voices of different users.
The candidate tone color attributes are tone color attributes which are recorded in the system in advance.
According to the technical scheme, the user can switch and set the preset tone attribute according to the specific voice control application scene, so that the system only recognizes and responds to the voice of the specific person, the purpose of shielding the voice of other irrelevant persons is achieved, and the voice control precision and the user experience are improved.
