It is open-source under the Apache-2.0 license. ## Decision facts: chatterbox-tts-api - **Requirements:** Requires a local setup environment that supports CUDA for optimal performance; Docker can simplify deployment. - **Adopt for:** Chatterbox-TTS-API is a locally hosted Python-based text-to-speech API with capabilities similar to ElevenLabs, offering an OpenAI-compatible interface for generating voice-cloned speech. - **License detail:** Chatterbox-TTS-API is distributed under the AGPL-3.0 license, ensuring any modifications or derivative works must be shared openly. ## Choose when ### Choose speechbrain if… - License: speechbrain is Apache-2.0, chatterbox-tts-api is AGPL-3.0. - Tags unique to speechbrain: asr, audio, audio-processing, deep-learning. - If you need to customize or experiment extensively with your speech processing pipeline, as SpeechBrain allows easy modifications via editable installs. ### Choose chatterbox-tts-api if… - License: chatterbox-tts-api is AGPL-3.0, speechbrain 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 speechbrain - If simplicity and ease of use are top priorities. SpeechBrain's extensive features might introduce unnecessary complexity for simpler speech processing tasks. - Avoid if you are constrained by computational resources, as expanding efforts toward training massive models could be resource-intensive and is one of the toolkit’s future development goals. ## 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. ## Common questions ### What is the difference between speechbrain and chatterbox-tts-api? speechbrain: A PyTorch-based Speech Toolkit. chatterbox-tts-api: Local OpenAI-compatible text-to-speech API using Chatterbox.
