Abstract
A method, an electronic device, and a non-transitory computer-readable medium storing instructions may be provided. The method may include receiving an audio signal; based on at least one preset trigger word being included in the received audio signal, determining whether the at least one trigger word included in the audio signal is misrecognized; based on the determining that the at least one preset trigger word is misrecognized, requesting an additional input from a user; and based on the additional input received in response to the request and the audio signal, executing a function corresponding to audio recognition.
Claims15
A method of processing a misrecognized audio signal in an electronic device, the method comprising:
- receiving an audio signal;
- detecting that at least one preset trigger word is included in the received audio signal;
- after detecting that the at least one preset trigger word is included in the received audio signal, determining, by a processor of the electronic device, whether the detected trigger word is misrecognized by measuring, by a wake-up word engine executed by the processor, a similarity between the at least one preset trigger word and the received audio signal based on frequency components extracted from the received audio signal,
- wherein the wake-up word engine comprises an acoustic model trained with acoustic information for the preset at least one trigger word;
- based on determining that the detected trigger word is misrecognized, requesting an additional input from a user;
- and
- based on the additional input from the user received in response to the requesting and the received audio signal, controlling, by the electronic device, whether to execute a function corresponding to audio recognition or to terminate the audio recognition.
An electronic device for processing a misrecognized audio signal, the electronic device comprising:
- a memory storing one or more instructions;
- and
- at least one processor configured to execute the one or more instructions,
- wherein the at least one processor is configured to:
- detect that based on at least one preset trigger word is included in the received audio signal,
- after detecting that the at least one preset trigger word is included in a received audio signal, determine whether the detected trigger word is misrecognized by measuring, by a wake-up word engine executed by the at least one processor, a similarity between the at least one preset trigger word and the received audio signal based on frequency components extracted from the received audio signal,
- wherein the wake-up word engine comprises an acoustic model trained with acoustic information for the preset at least one trigger word,
- based on determining that the detected trigger word is misrecognized, request an additional input from a user;
- and
- based on the additional input from the user received in response to the request and the received audio signal, control whether to execute a function corresponding to audio recognition or to terminate the audio recognition.
A non-transitory computer-readable medium storing instructions, that when executed by a processor, causes the processor to:
- receive an audio signal;
- detect that at least one preset trigger word is included in the received audio signal;
- after detecting that the at least one preset trigger word is included in the received audio signal, determine whether the detected trigger word is misrecognized by measuring, by a wake-up word engine executed by the processor, a similarity between the at least one preset trigger word and the received audio signal based on frequency components extracted from the received audio signal,
- wherein the wake-up word engine comprises an acoustic model trained with acoustic information for the preset at least one trigger word;
- based on determining that the detected trigger word is misrecognized, request an additional input from a user;
- and
- based on the additional input from the user received in response to the request and the received audio signal, control whether to execute a function corresponding to audio recognition or to terminate the audio recognition.
