Audio pipe to external program

[jneuendorf]

I am in a very similar situation regarding both

1. my telephony expertise and
2. that I want to use Asterisk solely for sending/receiving the caller’s audio to/from an external server as a stream (realtime audio passing i.e. no recordings) - meaning the external server could basically be replaced by a human on another phone.

From what I’ve read so far, I also get the impression that a lot of approaches out there aim to solve either speech-to-text (STT) or text-to-speech (TTS) but not both (STS). For me, it’s also unclear which interface should be used for what purpose…

Which of the following approaches is the easiest/best for Asterisk for STS?

• WebRTC
• AEAP
• ARI
  • External Media: A new way to get media in and out of Asterisk ⋆ Asterisk
  • https://wiki.asterisk.org/wiki/display/AST/External+Media+and+ARI
• UniMRCP
