Check Transcript

Now that you have a normalized transcript and a recognition transcript, you can check the transcript for any large, mismatched sections, and also generate some location pointers for the subsequent alignment task.

To check a transcript

For example:

http://localhost:13000/action=AddTask&Type=TranscriptCheck&TxtFile=C:\data\transcript.txt&CtmFile=C:\misc\speechtext.ctm&Out=AlignResults.ctm&DiagFile=myResults.diag

This action uses port 13000 to instruct IDOL Speech Server, which is located on the local machine, to compare the transcript.txt and speechtext.ctm files to produce the transcript file with approximate timestamps (AlignResults.ctm), and the diagnostics file (myresults.diag). The diagnostics file contains information on how well the speech-to-text transcript file and the normalized transcript file match.

The AlignResults.ctm output file is in the following format:

She 0.000 255.190
was 0.000 255.190
the 0.000 255.190
guardian 0.000 255.190
of 0.000 255.190

The file contains approximate timings of the transcript words in the audio file. You can use this information as the first step to aid the subsequent alignment task.

This action returns a token. You can use the token to:
