1 Capturing DTMF with Asterisk and UniMRCP

A common question new developers have is how to capture DTMF key presses when using speech recognition with Asterisk. There are two ways to do this when working with the res_unimrcp.so module and the MRCPRecog() and SynthAndRecog() applications. Using DTMF…

2 MRCPRecog()

MRCPRecog() is a dialplan application provided by the res_unimrcp.so module (see Developing Speech Applications on Asterisk for more information) that performs basic automatic speech recognition (ASR). It can play an audio file and allow the caller to interrupt…

3 MRCPSynth()

MRCPSynth() is a dialplan application provided by the res_unimrcp.so module (see Developing Speech Applications on Asterisk for more information) that performs text-to-speech (TTS) synthesis of plaintext or SSML-formatted documents. Application MRCPSynth(text,options)…

4 SynthAndRecog()

SynthAndRecog() is a dialplan application provided by the res_unimrcp.so module (see Developing Speech Applications on Asterisk for more information) that performs basic automatic speech recognition (ASR) while also playing out synthesized audio (TTS). Callers…
