New

A new global endpoint is now available at global.rt.speechmatics.com. This address automatically routes connections to the nearest region, providing the lowest latency and eliminating the need to hard-code specific regional endpoints into your applications.

Regional endpoints such as eu.rt.speechmatics.com and us.rt.speechmatics.com remain available for customers with specific data residency requirements.

Refer to the Realtime transcription documentation for full details.
