Title: Speech pause recognition method
Inventor: LUCIONI GONZALO DR ING
IPC: G10L25/78
Filed: 1997-07-16
Granted: 1999-02-11
Abstract: The method involves recognizing a speech pause within a sound consisting of a mixture of speech ("ZWEI", HG) and background noise, in which the sound is converted into digital data, which are processed in successive frames (Sk). A sum of the data of at least one frame is determined, and the sums of successive frames are supplied to a first digital filter (14).  This determines a pulse value (P) under consideration of a first adaptation function, which represents the energy capacity of the sound within a frame. The sums of successive frames are supplied furthermore to a second digital filter (16) which determines a background value (H) under consideration of a second adaptation function. This represents the average energy capacity within a frame. An evaluation signal (VAD) for signalling an existing speech pause is produced, if the pulse value is larger than the background value plus a predetermined threshold level.
