Speaking Variables to Callers
System variables can be entered in the place of wav file name in the Wav Editor. The value of the system variable will then be spoken. This applies to $NAM, $POS and $ETA in queuing call flows and to any variable that contains numeric values. Numbers are spoken as a series of single digits, for example 123 is spoken as "one two three". To speak 123 as "one hundred and twenty-three" requires TTS to be installed and a Speak Text action used.
