Samsung patents method to fix misheard voice commands

Samsung has patented a method for electronic devices to detect when a voice command is misheard. The system compares the sound to a known trigger word and asks the user for extra input if it is unsure, preventing wrong actions.

Why it mattersThis helps ensure voice assistants do not accidentally perform tasks based on misunderstood commands.

In the filing’s own words

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.

What exactly they claim (claim 1)

1. 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.
