VoiceSmith [WIP]

VoiceSmith makes it possible to train and infer on both single and multispeaker models without any coding experience. It fine-tunes a pretty solid text to speech pipeline based on a modified version of DelightfulTTS and UnivNet on your dataset. Both models were pretrained on a proprietary 5000 speaker dataset. It also provides some tools for dataset preprocessing like automatic text normalization.

If you want to play around with a model trained on a highly emotional emotional 60 speaker dataset using an earlier version of this software click here.



  • OS: Windows or any Linux based operating system. If you want to run this on macOS you have to follow the steps in build from source in order to create the installer. This is untested since I don’t currently own a Mac.
  • Graphics: NVIDIA GPU with CUDA support is highly recommended, you can train on CPU otherwise but it will take days if not weeks.
  • RAM: 8GB of RAM, you can try with less but it may not work.
