In the fast-evolving world of artificial intelligence, training models on multilingual datasets has become a necessity. The Multilingual PL-BERT checkpoint is a game-changer for those working with the StyleTTS2 framework. This guide will walk you through the process of integrating this checkpoint into your StyleTTS2 setup with ease.

What You Will Need

• Access to a machine capable of running Python and PyTorch.
• Your existing StyleTTS2 repository set up.
• The Multilingual PL-BERT model files.

Step-by-Step Instructions

Training the StyleTTS2 model using the new Multilingual PL-BERT checkpoint can be done by following these steps:

1. Create a new folder in your StyleTTS2 repository under the Utils directory. You might name it PLBERT_all_languages.
2. Copy and paste the following files into this new folder:
   • config.yml
   • step_1100000.t7
   • util.py
3. Update your main StyleTTS2 configuration file:
   • Change PLBERT_dir to the path of your new folder: Utils/PLBERT_all_languages.
   • Adjust your imports from:
     • from Utils.PLBERT.util import load_plbert to from Utils.PLBERT_all_languages.util import load_plbert.
4. If preferred, you can also replace the existing files in Utils/PLBERT directly, eliminating the need for adjustments in your code.
5. Next, you need to create your training and validation files. Use espeak to generate files that match the format in the Data folder of your StyleTTS2 repository. Make sure to change the language argument to phonemise texts that are not in English. Refer to the proper language codes available here. For instance, use es-419 for Latin American Spanish.

Understanding the Process Through an Analogy

Imagine you are a chef preparing a multicultural feast. You have your recipes (model files) that dictate how each dish should be cooked (trained), but you need to gather the right ingredients (languages) from different cultures. To make sure every dish is served correctly, you organize your kitchen (StyleTTS2 repository) with separate cupboards for each cuisine (the new folder for PL-BERT). With the right setup and ingredients, you can create a delicious banquet (train the multilingual model) that everyone will enjoy!

Troubleshooting Ideas

If you encounter any issues during the training process, consider the following troubleshooting steps:

• Double-check the paths you’ve entered for accuracy—any typos can throw everything off.
• Ensure that all required files are in the correct format and located in their respective folders.
• Review any error messages for hints on what might be causing the problem.
