# 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

- Send an `AddTask` action to IDOL Speech Server, and set the following parameters:

  `Type` | The task name. Set to `TranscriptCheck`.
  `TxtFile` | The normalized transcript file.
  `CtmFile` | The speech-to-text transcript file produced from the audio file.
  `Out` | The file to write a transcript that contains the approximate timestamps to.
  `DiagFile` | The alignment diagnostics file to generate.

For example:

    http://localhost:15000/action=AddTask&Type=TranscriptCheck&TxtFile=C:\data\transcript.txt&CtmFile=C:\misc\speechtext.ctm&Out=AlignResults.ctm&DiagFile=myResults.diag

This action compares 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:

- Check the task status. See Check the Status of a Task.
- Retrieve the results files. See Get Task Results.
