摘要
A voice activity detection unit is configured to receive at least two electric input signals in a number of frequency bands and a number of time instances, k and m being frequency band and time indices, respectively, (k, m) defining a specific time-frequency tile of said electric input signal. The voice activity detection unit is configured to provide a resulting voice activity detection estimate comprising one or more parameters indicative of whether or not a given time-frequency tile contains or to what extent it comprises a target speech signal. The voice activity detection unit comprises a) a first detector for analyzing the time-frequency representation of the electric input signals and identifying spectro-spatial characteristics of said electric input signals, and b) and is configured for providing said resulting voice activity detection estimate in dependence of said spectro-spatial characteristics. The invention may be used in hearing aids, table microphones, speakerphones, etc.
