Gladia

Production speech-to-text. The STT default for many companies.

End-to-end speech recognition platform — real-time streaming, batch transcription, speaker diarization, and language detection. Strong on accented speech, telephony audio, and long-form recordings.

Production speech-to-text + audio intelligence API.

Speech recognition API with batch and real-time streaming transcription, speaker diarization, and language detection. Its Universal models pair with optional Speech Understanding features (summarization, sentiment, redaction) so a single API can build conversation-intelligence products. Starts with a free credit and pay-as-you-go, per-second billing.

Enterprise speech APIs — real-time STT, TTS, and voice agents.

Speechmatics provides speech-to-text (batch and sub-second real-time), text-to-speech, and a Flow API for building voice agents, with accuracy that holds up across accents and dialects in 55+ languages. The same engine deploys in cloud, container, on-prem, or fully on-device, and it powers products from Adobe, LiveKit, and Ubisoft.

Text-to-speech, voice cloning, and multilingual dubbing.

Hosted speech synthesis at near-human quality — TTS, voice cloning, multilingual dubbing, and conversational voice agents. Default choice when you need a voice that sounds like a person, not a robot.
