## Choose when

### Choose IMS-Toucan if…

- License: IMS-Toucan is Apache-2.0, chatterbox-tts-api is AGPL-3.0.
- Requirements: Python version 3.10 is recommended..
- Tags unique to IMS-Toucan: deep-learning, pytorch, speech-processing, text-to-speech.
- Use IMS-Toucan if your project requires high language coverage, especially in lesser-known or endangered languages.

### Choose chatterbox-tts-api if…

- License: chatterbox-tts-api is AGPL-3.0, IMS-Toucan is Apache-2.0.
- Requirements: Requires a local setup environment that supports CUDA for optimal performance; Docker can simplify deployment..
- Tags unique to chatterbox-tts-api: ai, chatgpt, chatterbox, cuda.
- When you need a self-hosted solution that mirrors the functionality of ElevenLabs or other proprietary TTS services and requires compatibility with existing ecosystems like Open WebUI or AnythingLLM.

## 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.

## When NOT to use chatterbox-tts-api

- If you require integrations specific to ElevenLabs' proprietary voice models as Chatterbox-TTS-API, despite its capabilities, does not directly support their unique voice libraries.
- For users needing a fully managed service without the complexities of local deployment and maintenance, like that offered by cloud-based TTS providers.
