FIELD: computer equipment for processing audio data.
SUBSTANCE: technical result is achieved by determining a primary voice activity detection solution (VAD) based on voice activity; determining the final VAD decision based on whether the primary decision signal tails are added; determining a measure of short-term voice activity based on past primary decisions; determining a measure of long-term voice activity based on past final decisions or past primary decisions; and determining an alternative final solution for adjusting the addition of signal tails based on a measure of short-term voice activity and a measure of long-term voice activity.
EFFECT: elimination of audio data reproduction artefacts with cutting off the ends of the last speech segments, such as a speech fragment ending with a non-speech explosion.
