st.markdown('''# Mockingbird TTS Demo
This page is a demo of the openly available Text to Speech models for various languages of interest. Currently, 3 synthesizers are supported:
- [**Meta's Massively Multilingual Speech (MMS)**](https://ai.meta.com/blog/multilingual-model-speech-recognition/) model, which supports over 1000 languages.[^1]
- [**Coqui's TTS**](https://docs.coqui.ai/en/latest/#) package;[^2] while no longer supported, Coqui acted as a hub for TTS model hosting and these models are still available.
- [**ESpeak-NG's**](https://github.com/espeak-ng/espeak-ng/tree/master)'s synthetic voices**[^3]
Voice conversion is achieved through Coqui.
Notes:
1. ESpeak-NG seems to have the worst performance out of the box, but it has a lot of options for controlling voice output.
2. Where a synthesizer supports multiple models/voices, I manually pick the appropriate model.
3. Not all synthesizers support a given language.
