Developer-first speech-to-text API with industry-leading accuracy
Transcribe pre-recorded files in minutes or stream live audio through a real-time endpoint, with punctuation, casing, and formatting applied automatically.
Recognize speech across more than 57 languages and dialects, with benchmarked accuracy that the company reports as the best among major vendors.
Layer language identification, sentiment analysis, topic extraction, summarization, and translation on top of any transcript to turn audio into structured intelligence.
Generate exact word-level timing for media, subtitles, accessibility, and content indexing workflows.

Accurate audio and video transcription, with an API for developers
Upload audio or video by file, link or live browser recording. Vatis accepts MP3, WAV, M4A, FLAC, AAC and OGG audio plus MP4, MKV, AVI, MOV and WebM video, and typically returns a 1-hour file in under a minute.
Interviews, meetings and podcasts get automatic speaker labels, extracts of key quotes, chapter markers and a summarised version of the recording, all generated from the same transcript.
The asynchronous Speech-to-Text endpoint supports payloads of any length and returns diarization and word-level timestamps. Every new account gets €10 of credit for building against the API.
Turn a transcript into subtitles or captions in another language without leaving the platform, and export timed files as SRT or VTT for video workflows.
