Example

http://localhost:13000/action=AddTask&Type=TelWavToText&File=C:/myData/tel.wav&Out=TelTranscript.ctm&Lang=ENUS

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