Overview
AI Speech-to-Text API converts recorded audio into accurate, readable text through a single REST endpoint. Send an audio file or a URL and receive a transcript with per-segment timestamps, detected language, and confidence scores.
The API accepts common audio and video container formats, handles long recordings, and returns structured JSON that is ready to store, index, or render as subtitles. Automatic language detection means you do not need to know the language of a recording in advance.
Billing is usage based. You are charged only for the minutes of audio you transcribe, with no minimum commitment and no monthly platform fee. Access is authenticated with an API key issued to you when you subscribe.
Highlights
- Per-segment timestamps and confidence scores returned as structured JSON
- Automatic language detection, so you do not need to specify the language up front
- Usage based pricing billed per minute of audio, with no minimum commitment
