DOUBLE-TALK STATE DETECTION METHOD AND DEVICE, AND ELECTRONIC DEVICE

摘要

The present application discloses a double-talk state detection method, a double-talk state detection device and an electronic device, and relates to the field of voice processing technology. The specific implementation scheme includes: calculating an energy ratio between a first energy of an error signal in each sub-band of M sub-bands and a second energy of a filtered signal in the same sub-band as the error signal, thereby obtaining M energy ratios, where the error signal is a difference between an input signal collected by a microphone and the filtered signal, the filtered signal is a signal obtained after performing filtering process on a reference signal, and M is a positive integer; performing a first smoothing processing on the M energy ratios to obtain M first energy smoothing ratios, and performing a second smoothing processing on the M first energy smoothing ratios to obtain M second energy smoothing ratios; performing double-talk state detection based on the M first energy smoothing ratios and the M second energy smoothing ratios to determine a state of the input signal. The state detection accuracy can be improved.
