On-prem availability

Pre-recorded and streaming transcription run on-prem, as a container deployment or a virtual appliance. This page covers on-prem availability. For Speechmatics-hosted deployments, see Feature availability.

A check mark marks an available combination. An em dash means the combination is either unavailable or not established, and carries no roadmap position either way.

Region does not apply on-prem. Regions are an attribute of SaaS on Cloud, because on-prem deployments are customer-hosted.

Readiness on-prem

On-prem ships as versioned containers, so the question is which release you need rather than whether a combination is production-ready.

Interaction pattern	Model	On-prem
pre-recorded	Standard	Released
pre-recorded	Enhanced	Released
pre-recorded	Melia 1	Released
streaming	Standard	Released
streaming	Enhanced	Released

Feature availability on-prem depends on the container release you are running. Check Accessing images for the current releases, and the release notes for the change that introduced a given feature.
