The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The present disclosure provides an echo cancellation method 10, which is applied to a cloud server, where the cloud server and other devices may be under an account and maintain communication connection. Referring to fig. 1, the echo cancellation method 10 includes steps S11-S15, described in detail below:
and step S11, collecting a user voice instruction.
The server can acquire the instruction of the user through the voice acquisition equipment so as to respond. The user voice instruction may be obtained in various ways, for example, the user may send an instruction to the server through a mobile terminal such as a mobile phone, and in some voice multi-round interaction scenarios, obtaining the user instruction may include: receiving user voice sent by voice acquisition equipment, wherein the user voice is acquired through a microphone of the voice acquisition equipment; and carrying out voice recognition on the voice of the user to obtain a user instruction.
And step S12, generating corresponding response voice based on the voice command, and controlling the corresponding equipment to play the response voice.
The server responds after receiving the user instruction, generates response voice for providing information or prompting operation for the user, and can send the response voice to corresponding equipment for playing so as to feed back the user voice instruction, wherein the equipment for playing can be equipment with a loudspeaker, such as an intelligent sound box, an intelligent television and the like. In some scenes, the response voice is sent to the intelligent sound box, and the response voice is played through the intelligent sound box, so that interaction with a user is realized; in other scenes, the smart sound box serves as an acquisition inlet of a user instruction, the smart television serves as another interactive device to display related information or display related content according to the requirements of the user, and the server can send the generated response voice to the smart television and play the response voice through a loudspeaker of the television.
And step S13, controlling the voice collecting equipment to ignore the response voice so as to avoid the response voice being collected by the voice collecting equipment and mistakenly used as the voice instruction of the user.
The response voice is used for feeding back to the user, so that the response voice is ignored in order to avoid wrong judgment caused by collection and recognition of the response voice again, and accuracy and reliability of a voice interaction process are guaranteed.
In one embodiment, as shown in fig. 2, step S13 may include: step S131, during the period of answering voice playing, controlling the voice collecting device to close the microphone.
The microphone of the voice acquisition equipment used as the entrance for acquiring the user instruction is closed, so that the reception is cut off, the played response voice is prevented from being received, transmitted and identified again, and the transmission cost and the voice identification calculation cost are avoided while the false identification is avoided.
In an embodiment, step S131 may include: determining the playing time length of the response voice; and controlling the voice acquisition equipment to close the microphone from the beginning of playing the response voice until the playing time length is up. According to the embodiment, the voice acquisition equipment is controlled according to the playing duration of the response voice, and the microphone is ensured to be opened in time, so that the voice instruction sent again by the user according to the response voice is ensured to be received, and the reliability of multi-round voice interaction is improved.
In an embodiment, as shown in fig. 3, step S13 may further include: and step S132, responding to the collected response voice, and controlling the voice collecting equipment not to respond to the response voice. The embodiment continuously collects voice, avoids omitting voice instructions of users, simultaneously does not answer the collected response voice, and avoids misjudging the response voice into wrong instructions, thereby ensuring the reliability of multi-round semantic interaction.
In one embodiment, as shown in fig. 4, step S132 may include: step S1321, caching the response voice; step S1322, receiving an audio frequency acquired by the voice acquisition device; step S1323, comparing the response voice with the voice frequency by voice print; responding to the fact that the similarity between the response voice and the voice print of the audio frequency reaches a preset threshold value, and not responding to the audio frequency; and responding to the fact that the similarity between the response voice and the voice print of the audio does not reach a preset threshold value, and performing voice recognition on the audio.
In this embodiment, the server caches the generated response voice, and after the prompt voice is played, the voice acquisition device acquires the audio and sends the audio to the server, and the server does not directly perform voice recognition, but performs voiceprint comparison on the received audio and the cached prompt voice, and the calculation amount of the voiceprint comparison is lower than that of the voice recognition. Judging whether the voiceprint and the voice recognition are the same sound according to whether the similarity of the voiceprint exceeds a preset threshold value, if so, directly discarding the voiceprint without performing voice recognition operation, thereby saving the calculated amount; and if the sound is judged not to be the same sound, voice recognition is carried out, and the condition that the user instruction is not missed is ensured.
In another embodiment, as shown in fig. 5, step S132 may further include: step S1324, determining the time length from sending the response voice to receiving the audio; performing voice recognition on the audio in response to the elapsed time length exceeding a preset threshold; and in response to the elapsed time not exceeding a preset threshold, performing a voiceprint comparison step. After the prompt voice sent by the server exceeds a certain time, the voice received after the certain time is exceeded basically cannot be the income of the prompt voice again, therefore, in the implementation, the voice print recognition is carried out through the preset threshold value of the time length and the audio frequency received within the preset threshold value of the time length, the misjudgment caused by the collected response voice is avoided, meanwhile, the voice print recognition is not carried out on the audio frequency received after the time length exceeds the threshold value, the semantic recognition is directly carried out, and the feedback of the user instruction is ensured.
In an embodiment, after the voiceprint comparison is performed or the duration of the voiceprint comparison exceeds the preset threshold, the cached prompt voice can be deleted, so that the storage cost is reduced, and the performance reduction caused by excessive storage is avoided.
