[English]
This Space showcases a cutting-edge text-to-speech model for Fongbe, a major language spoken in Benin and parts of Togo.

🔍 **How to Use**  
Type a short sentence in **Fon** and press “Submit” to hear the synthesized voice. The model outputs audio in real-time using a pretrained multilingual vocoder.

🌍 **About the Language**  
Fon is a Niger-Congo language with over 2 million speakers. It is used in education, media, and daily communication, yet remains underrepresented in speech technology. This demo helps close that gap by making TTS more accessible for low-resource African languages.
