## Example

    http://localhost:13000/action=AddTask&Type=WavToTextPunct&File=C:/myData/Speech.wav&Out=SpeechTranscript.ctm&Lang=ENUS

This action uses port `13000` to instruct HPE IDOL Speech Server, which is located on the local machine, to perform the `WavToText` task on the `Speech.wav` file and write the results to the `SpeechTranscript.ctm` file. The `Speech.wav` file contains U.S. English dialect speech and punctuation.
