Hi Team,
Could one of the maintainers kindly review this PR? It enhances the organization’s TTS capabilities and introduces an additional tool for users to choose from.
Thank you!

@Saransh-Shankar sorry for the late response. The test is still failing. See here https://github.com/fixie-ai/ultravox/actions/runs/16160094945/job/46896709272?pr=303

I tried to check out your branch, remove the poetry.lock file, and regenerate it by running just install, but I am getting other dependency related errors.

Please try to run just test from your end to ensure everything passes.
