How to fill out forced alignment for speech

How to fill out forced alignment for speech:

1. Firstly, you need to obtain a speech transcription or text that corresponds to the speech you want to align. This can be a written script or a recorded speech that has been transcribed.
2. Next, make sure you have a forced alignment software or tool. There are various options available, such as the Gentle Forced Aligner or Prosodylab-Aligner, among others. Choose the one that suits your needs and download or install it.
3. Open the forced alignment software and load the speech transcription or text file into the program. Follow the instructions provided by the specific software you are using to import the file correctly.
4. Configure the alignment settings according to your preferences. This may include specifying the language, audio input file format, and other parameters that are necessary for a successful alignment.
5. If required, you may need to preprocess the audio file by cleaning it, removing any background noise, or normalizing the volume levels. This step is crucial to ensure better accuracy during the alignment process.
6. Start the forced alignment process by clicking the appropriate button or executing the required command in the software. This will initiate the alignment algorithm, which will align the speech transcription with the corresponding audio.
7. Depending on the length of the audio and complexity of the speech, the alignment process may take some time. Be patient and wait for the software to complete the alignment task.
8. Once the alignment is done, you can typically preview the results and make necessary adjustments if required. Some tools allow you to listen to the aligned audio or view the graphical representation of the alignment. Use this opportunity to ensure the alignment is accurate and make any necessary corrections.
9. Finally, save the aligned speech in the desired format or export it to other programs or platforms for further analysis or use.
