Dynamics 365 Contact Center- Use constrained grammars for speech recognition

We are announcing the ability to use constrained grammars for speech recognition in Dynamics 365 Contact Center. This feature will reach general availability on September 30, 2025.

How does this affect me?
This feature delivers better accuracy, performance, and cost than traditional semantic-based speech-to-text (STT) AI engines. The engine processes grammars that follow the Speech Recognition Grammar Specification (SRGS) standard, which are written in an XML-based format called GrXML. The engine converts spoken audio (utterances) into text that follows the grammar's rules.

What action do I need to take?
This message is for awareness, and no action is required.
