<p>A voice activity detection method and apparatus, and an electronic device are provided. The method includes: obtaining a time domain parameter and a frequency domain parameter from an audio frame; obtaining a first distance between the time domain parameter and a long-term slip mean of the time domain parameter in a history background noise frame, and obtaining a second distance between the frequency domain parameter and a long-term slip mean of the frequency domain parameter in the history background noise frame; and judging whether the audio frame is a foreground voice frame or a background noise frame according to the first distance, the second distance and a set of decision inequalities based on the first distance and the second distance, in which at least one coefficient in the set of decision inequalities is a variable, and the variable changes with a voice activity detection operation mode or features of an input signal. The above technical solutions enable the judgment criterion to have an adaptive adjustment capability, thus improving the performance of the voice activity detection.</p> |
