Name

BackgroundDetect() — Plays a file in the background and detects talking

Synopsis

BackgroundDetect(filename[,sil[,min[,max]]])

Similar to Background(), but attempts to detect talking.

During the playback of the file, audio is monitored in the receive direction. If a period of non-silence that is greater than min milliseconds yet less than max milliseconds and is followed by silence for at least sil milliseconds occurs, the audio playback is aborted and processing jumps to the talk extension, if available.

If unspecified, sil, min, and max default to 1,000 ms, 100 ms, and infinity, respectively.

exten => 123,1,BackgroundDetect(tt-monkeys)
exten => 123,2,Playback(im-sorry)
exten => talk,1,Playback(yes-dear)
