Choose MARS5-TTS if…
- License: MARS5-TTS is AGPL-3.0, bark is MIT.
- Pricing: Open-source version is free for non-commercial use; commercial licenses are available upon request by contacting help@camb.ai..
- Requirements: Supports custom development through Docker, allowing you to build a base image and extend with your own inference scripts.; Docker integration provides flexibility but requires users to have the necessary environment setup for usage..
- Tags unique to MARS5-TTS: docker-support, jupyter-notebook, prosody, speech-synthesis.
- When you have projects requiring nuanced prosody control for more natural sounding synthesized speech, as MARS5-TTS is specifically highlighted for its prosodic synthesis abilities.
When NOT to use MARS5-TTS
- When you require immediate access to pre-built output-generating Docker images, since as of now these are not yet available despite plans for their future addition.
- If your project needs a model that does not involve the GNU AGPL-3.0 license, because this might impose restrictions on how derivative works can be distributed.
Choose bark if…
- License: bark is MIT, MARS5-TTS is AGPL-3.0.
- Tags unique to bark: audio-generation, cpu, generative-model, gpu.
- Use Bark when you need to generate audio from text prompts and have access to hardware with at least 8GB of VRAM for smaller models or 12GB for the full version.
When NOT to use bark
- Avoid Bark if your hardware is limited to older GPUs or CPUs, as inference times might be significantly slower, impacting productivity.
- Do not use Bark if you require a package installed via `pip install bark`, as this installs a different package not managed by Suno.
- Bark may not be suitable if you need a text-to-speech solution that does not require setting up an environment flag for smaller models to fit into 8GB VRAM.
