The ClusterSpeechToTextTel
task performs clustering of two speakers in a phone call, and uses the resulting speaker clusters to improve speech-to-text performance slightly by using speaker-sided acoustic normalization. As before, any telephony artifacts such as dial tones or DTMF tones are included, interspersed with the recognized words.

http://localhost:13000/action=AddTask&Type=ClusterSpeechToTextTel&File=C:/myData/Speech.wav&Out=SpeechTranscript.ctm&Lang=ENUS
This action uses port 13000
to instruct IDOL Speech Server, which is located on the local machine, to perform the ClusterSpeechToTextTel
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.
