Function
This module detects a DTMF input (tone dialling) or spoken words (ASR, Automatic Speech Recognition) and executes a branch in the program. To prompt the user to press a key, a voice prompt is played.
If no input is recognised, or an incorrect digit is pressed or a word is not recognised, an error voice prompt can be configured which is played to reprompt the user to try again.
Program execution continues using the output which corresponds to the DTMF key pressed or the word spoken. If this output is not connected, and the maximum number of allowed tries has not yet been reached, the error voice prompt is played and recognition is restarted. If the maximum number of tries is reached, program execution continues at the error output. If no object is connected to this output, the system hangs up.

Note on speech recognition:
Speech recognition does not recognise every speaker and every word. Consider using alternative command words. Short words, like “yes” are more difficult to recognise. Ask callers to speak slowly and clearly if the system does not recognise them. When specifying command words consider how the word is spoken, rather than how it is written. This applies particularly to foreign words. The system will try to recognise these as if they had been spoken in the native language. For example:
