Bengali speech synthesis for production voice apps
Bengali is spoken by more than 300 million people across Bangladesh, India, and beyond. If your voice agent, IVR, or narration product speaks to them, text-to-speech has to get the details right: phone numbers and codes read exactly as written, names pronounced the way Bengali speakers expect, and text that mixes Bengali with English spoken in one voice.
Soniox TTS generates Bengali speech over a real-time WebSocket, starting audio from the first few words, or with a single REST request, through one multilingual API built for 60+ languages. Every voice speaks Bengali, you can clone your own voice, mix languages in one sentence, and get character-level timestamps.
