Classification: G10L

Abstract:
A speech detection devicefor detecting a speech signal in a received signal and for determining a speech time slot, a switch-on threshold detector for delivering first detection information when the energy content of the received signal exceeds a first energy threshold, and including a switch-off threshold detector for delivering second detection information when the energy content of the received signal falls short of a second energy threshold, the second energy threshold being smaller than the first energy threshold, and including information processing means for receiving and processing the first detection information and the second detection information and for terminating the delivery of speech detection information featuring a speech time slot when the second detection information was received during a first switch-off period, characterized in that the information processing means are arranged for additionally terminating the delivery of speech detection information if the first detection information was not received during a second switch-off period and/or if the first detection information was not received during a third switch-off period, whereas the beginning of the third switch-off period is determined when the second detection information is received for the first time after the first detection information had not been received.
