Choose IMS-Toucan if…
- IMS-Toucan is primarily Python; TTS is Jupyter Notebook.
- License: IMS-Toucan is Apache-2.0, TTS is MPL-2.0.
- Requirements: Python version 3.10 is recommended..
- Tags unique to IMS-Toucan: speech-processing, text-to-speech.
- Use IMS-Toucan if your project requires high language coverage, especially in lesser-known or endangered languages.
When NOT to use IMS-Toucan
- Avoid IMS-Toucan if your project only requires support for a few major languages since it may introduce unnecessary complexity.
- Do not use IMS-Toucan if you cannot meet the setup requirements, including specific Python and library versions as well as potential difficulties in setting up on MACs.
Choose TTS if…
- TTS is primarily Jupyter Notebook; IMS-Toucan is Python.
- License: TTS is MPL-2.0, IMS-Toucan is Apache-2.0.
- Tags unique to TTS: dataset-analysis, gantts, glow-tts, melgan.
- Use TTS when you require advanced deep learning models such as Tacotron, Tacotron2, MelGAN, and Multiband-MelGAN for high-quality voice synthesis tasks.
When NOT to use TTS
- Avoid TTS if you require support for Python versions above 3.8 as it does not support later releases.
- Do not use TTS if the only requirement is to run simple, unmodified speech synthesis tasks without training or custom development; other tools may offer easier setup.
