<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">It may be worthwhile adding some information about using this with the AGC and DENOISE dialplan functions.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Hm. How do you see this being used with those (apart from using AGC/DENOISE to 'clean up' the audio stream?)</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">That's exactly how I foresee it being used but giving an example to ensure the correct order yields that result would head off a case in the future of something trying it and not having it work (because they did TALK_DETECT before AGC/DENOISE). Examples are good.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This patch adds a new channel function TALK_DETECT that, when set on a channel, causes events indicating the start/stop of talking on a channel to be emitted to both AMI and ARI clients. Why a channel function? Because both ARI and AMI can set it on the channel, making it (slightly) more useful than existing speech/silence detection dialplan applications.
The function allows setting both the silence threshold (the length of silence after which we decide no one is talking) as well as the talking threshold (the amount of energy that counts as talking):
same => n,Set(TALK_DETECT(set)=2500,256)
Parameters can be updated on a channel:
same => n,Set(TALK_DETECT(set)=) ; Enable talk detection
same => n,Set(TALK_DETECT(set)=,128) ; Set the talking threshold on the existing talk detection to 128
And talk detection can be removed:
same => n,Set(TALK_DETECT(remove)=)
The events raised by the function use a nomenclature similar to existing AMI/ARI events.
For AMI: ChannelTalkingStart/ChannelTalkingStop
For ARI: ChannelTalkingStarted/ChannelTalkingFinished
Both 'end' events include the duration of talking that was detected (in milliseconds).</pre>
