Speech to Text

Speech to Text

Speech to Text transcribes audio in three interaction patterns, which differ in how you present audio for processing:

  • pre-recorded: submit a file and receive a complete transcript
  • streaming: send live audio and receive transcripts as you speak
  • agent STT: send live audio and receive complete speaker turns

Your choice of pattern determines which models you can use, and which features those models support. To understand how the three patterns relate to the Batch and Realtime APIs, see Understanding interaction patterns.

Developer quickstart

The quickest way to transcribe audio is in the web portal.

Choose a model and check availability

Pre-recorded and streaming transcription offer the Standard, Enhanced, and Melia 1 models. Agent STT offers Linden 1. See Models to compare them.

Availability depends on the combination of pattern, model, and deployment, so check the combination rather than the product name. See Feature availability.

Deployments

Speechmatics provides flexible deployment options tailored to your requirements. You can host the platform in your own environment, use our managed service, or choose a hybrid approach.

For deploying our API in your environment, contact sales, or see our on-prem documentation.
