Title:
DOUBLE TALK METHOD AND APPARATUS, ELECTRONIC DEVICE, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/245714
Kind Code:
A1
Abstract:
A double talk method and apparatus (300), an electronic device (400), and a computer-readable storage medium. The method comprises: acquiring a user sound and ambient noise in real time by using a microphone array (401) (S110); calculating the position of the mouth of a user relative to the microphone array (401) and the sound pressure level of the ambient noise according to a difference among signals acquired by microphones at different positions in the microphone array (401), and calculating a distance between an ear of the user and a loudspeaker (402) (S120); during speaking, determining an acquisition protection angle of the microphone array (401) according to the position of the mouth of the user relative to the microphone array (401), and controlling the microphone array (401) to acquire an audio signal within the acquisition protection angle (S130); and during hearing, determining an optimal gain value of the loudspeaker (402) according to the loudness of sound of a peer terminal received by the loudspeaker (402), the distance between the ear of the user and the loudspeaker (402), the sound pressure level of the ambient noise and the sensitivity of the loudspeaker (402), and controlling the loudspeaker (402) to play a sound signal of the peer terminal by using the optimal gain value (S140). The method can improve the double talk quality of a smart watch.
