One speech AI API for recognition, generation, and translation in 60+ languages
Soniox STT delivers high accuracy across 60+ languages, accents, numbers, names, and domain vocabulary, engineered for fast multi-speaker conversations and noisy environments.
Generate expressive speech in 60+ languages with audio tags, alphanumeric accuracy, seamless language switching, 200+ built-in voices, and instant voice cloning.
Translate speech in real time across roughly 3,600 language pairs, with low-latency output that starts before a sentence finishes and handles mid-sentence language switching.
Streaming models transcribe speech and start generating audio from the first few words, keeping interaction fast enough for live voice agents and captions.
Text to speech and voice AI across every device
Listen to books, PDFs, documents and web pages read aloud in a large library of lifelike AI voices.
Dictate instead of typing in almost any app, across Google Docs, Gmail, Slack, Outlook and more.
Turn documents or a short prompt into an AI podcast, and get instant summaries of what you are reading.
Use the web app, Chrome and Edge extensions, and native iOS, Android, Mac and Windows apps.
