Abstract: Disclosed are a voice enhancement method, apparatus and system and a computer-readable storage medium. The method includes acquiring a time-domain microphone signal and a time-domain bone conduction signal at the current moment; determining whether the signals are voice signals, if yes, performing a noise cancellation processing to the time-domain microphone signal by a pre-established DNN noise cancellation model, performing a frequency-domain noise cancellation processing to the time-domain bone conduction signal, if not, setting an output signal at the current moment as zero; performing a high-pass filtering processing to the time-domain microphone signal from which noise has been cancelled, to obtain a first output time-domain signal, performing a low-pass filtering processing to the time-domain bone conduction signal from which noise has been cancelled, to obtain a second output time-domain signal; obtaining an output time-domain signal at the current moment according to the first and second output time-domain signals.

Abstract: A voice signal detection method, a terminal device and a storage medium. Said method comprises: receiving a time domain signal detected by a bone conduction sensor in the terminal device, and acquiring time domain features in the time domain signal (S10); converting the time domain signal into a frequency domain signal, and acquiring frequency domain features in the frequency domain signal (S20); and when the time domain feature satisfies a first preset condition and the frequency domain feature satisfies a second preset condition, determining that a voice signal has been detected by the bone conduction sensor (S30). The voice detection is performed according to a signal detected by the bone conduction sensor, without the need of combining with a signal detected by a microphone, so that the voice detection is simpler, and moreover, as voice recognition is performed merely in combination with the bone conduction sensor, the cost is low.
