# TelWavToText

DEPRECATED:

The `TelWavToText` task is deprecated in IDOL Speech Server version 11.5 and later. Use the SpeechToTextTelephony task instead.

This task is still available for existing implementations, but it might be incompatible with new functionality. The task might be deleted in future.

The `TelWavToText` task converts a telephony audio file into a text transcript. In addition to transcribing speech, the task recognizes and transcribes dial tones including DTMF.

## Example

    http://localhost:15000/action=AddTask&Type=TelWavToText&File=C:/myData/tel.wav&Out=TelTranscript.ctm&Lang=ENUS

This action performs the `TelWavToText` task on the `tel.wav` file and writes the results to the `TelTranscript.ctm` file. The `tel.wav` file contains U.S. English dialect speech.
