Using NUAligner 2

There are three options for using NUAligner 2

  1. You wish to align a single audio files

    2. This is the most simple use case where you have one audio file and one transcription text file. Use the "Single File Alignment" tab and select the audio file and text transcription. Then click "Align", select where you would like to save the TextGrid file. NUAligner 2 will process the wave file and create a TextGrid in your "Save as" location.

  2. You wish to align multiple audio files to a single transcription text file

    3. In this case, you have a directory containing audio files that all have the same content, for example, scripted speech. Select the "Many Files to One Transcription" tab. Select a directory containing the wave files and the single text transcription that corresponds to the audio files. Click "Align" and select an output directory to save the resulting TextGrids. NUAligner 2 will create TextGrids with the same prefix as the audio files in the selected output directory.

  3. You wish to align multiple audio files which each have their own individual transcription text

    4. In this case, each wave file and transcription text file must be in the same directory and must contain the same prefix. For example:

    • audio001.wav
    • audio001.txt
    • audio002.wav
    • audio002.txt

    Select the "Many Files to Many Transcriptions" tab and select the location of the directory containing audio files and transcriptions text files. Click "Align" and select an output folder. NUAligner 2 will process all the wave files and generate TextGrids in the output directory.
