Example

http://localhost:13000/action=AddTask&Type=WavToText&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.
