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.
Voice AI agents and real-time speech-to-text for production call automation
Describe an agent in plain English and the platform sets up the voice, prompts, knowledge and call flow; then test, refine and deploy to a phone line, an app or the API.
Streaming transcription returns text while the caller is still speaking, covering dozens of languages and accents through the API or the built-in playground.
Hand the agent your own endpoints so it can book, look up and update records mid-call, then write the outcome back to Salesforce, HubSpot or Zoho.
Connect Twilio or Plivo, point a campaign at your contact list, and let the agent handle every call while you manage only the queue.
Industry leader for high-fidelity speech synthesis and voice cloning, though less focused on raw streaming STT infrastructure.
