Choose IMS-Toucan if…
- Requirements: Python version 3.10 is recommended..
- Tags unique to IMS-Toucan: deep-learning, pytorch, speech-processing.
- 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 dia if…
- Tags unique to dia: dialogue-generation, tts.
- When you require precise control over voice and script in the creation of highly realistic dialogues
- More GitHub stars (19k vs 2.2k) - visibility, not fit.
When NOT to use dia
- If your setup lacks a GPU, as Dia has not yet added CPU support
- In scenarios where immediate real-time performance is critical since the first run could be longer due to additional codec downloads
