Abstract:
A method and a device for optimizing a sound signal, belonging to the speech signal processing field. The method is used in a terminal comprising at least two sound collecting units and comprises: positioning sound sources at the periphery of the terminal by the at least two sound collecting units (102); selecting a specified sound source from each sound source that is determined through positioning (104); determining a sound signal sent from the specified sound source in the sound signals collected by the terminal on the basis of the spatial position of the specified sound source obtained through positioning (106); optimizing the volume of the sound signal sent from the specified sound source (108). During the collection of the sound signals, peripheral sound sources are screened and the sound signals sent from the screened sound source are optimized by the method and the device, and thereby the sound signal acquisition effect of the terminal is improved.
