World’s most accurate Bengali speech-to-text
The world’s most accurate real-time speech-to-text API for Bengali, powering voice agents, live systems, and applications across 60+ languages.
Trusted by teams building global voice products
Unmatched accuracy in Bengali and 60+ languages
Bengali is spoken by over 300 million people worldwide — across Bangladesh, India, and beyond. For years, Bengali speech-to-text has fallen short, failing at fundamentals like accurate and reliable recognition, multiple languages, and alphanumerics. It converted Bengali audio into words, but the words lacked meaning and context.
Soniox reimagined everything Bengali speech-to-text got wrong. You can speak naturally, switch languages mid-sentence, spell out codes and names, or ask for instant Bengali translation, all in real-time. Soniox doesn’t just transcribe Bengali speech – it understands it.
Bengali native-speaker accuracy
Accurate Bengali speech recognition across accents, dialects, and real-world conversational speech.

“We tried a dozen speech-to-text and translation services. Soniox is the best, so that's what we use.”
Automatically detect and switch languages with Bengali
Soniox identifies the language automatically and follows changes between Bengali and other languages as they happen, even within the same sentence.
