Demo for cascaded speech-to-speech translation (STST), mapping from source speech in any language, supported by the whisper, to target speech in Finnish.
Demo uses:
* OpenAI's [Whisper Base](https://huggingface.co/openai/whisper-base) model for speech translation
* Language Technology at the University of Helsinki en-fi model [Helsinki-NLP](https://huggingface.co/Helsinki-NLP/opus-mt-en-fi)
* Microsoft's [SpeechT5 TTS](https://huggingface.co/microsoft/speecht5_tts) model fine-tuned on subset of [VoxPopuli](https://huggingface.co/datasets/facebook/voxpopuli) dataset for text-to-speech
