I can send audio data to AVS constantly,but I don't know how mush audio bytes that avs need?When do I stop sending data?
This depends on which Automated Speech Recognition Profile you are using. If you are using one of the cloud based endpointing options, AVS will send down a StopCapture directive on the downchannel to let the app know when to stop sending audio bytes.
If you have not implemented the downchannel yet, instructions on how to do that can be found here.
