Title:
VOICE SIGNAL DETECTION METHOD, TERMINAL DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/052246
Kind Code:
A1
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 features satisfy a first preset condition and the frequency domain features satisfy a second preset condition, determining that the bone conduction sensor detects a voice signal (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, such 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.
