Nuance building block components are available as cloud-native containerized microservices for on premise or cloud deployments enabling the acceleration, development, and deployment of speech-to-text (STT) and text-to-speech (TTS) core technologies as well as Dialog (DLG) via a set of Nuance APIs. With these components, you will have the flexibility to build your own solution or if desired, engage in a collaborative approach with our highly experienced designers and professional services teams.
UniMRCP Connector is an on-premises software component that provides a native MRCP v1 or v2 bridge connection to leading providers of Conversational AI Services in the cloud such as Speech Recognition and Text-to-Speech. The connector enables traditional on premise IVR’s using the MRCP protocol for ASR and TTS to now consume those resources in the cloud with limited modifications to your existing IVR application.
Voicegain’s deep learning ASR with speech grammars or use of large vocabulary transaction for Voice Bots and IVR’s with support for eight languages all accessible via a standard MRCP protocol.

Nuance Software End of Life (EOL)
Nuance, now a Microsoft company, has long been a market leader in Conversational AI and voice technology, making this phase-out especially significant. All Nuance products are slated to be retired by June 30th, 2027—including its flagship Nuance Recognizer ASR (Automatic Speech Recognition) and Nuance Vocalizer TTS (Text-to-Speech) — which have powered countless interactive voice response (IVR) systems worldwide. As these core components sunset, businesses must adapt quickly to continue delivering reliable, high-quality customer service.
For organizations deeply reliant on Nuance ASR and TTS, this transition poses both challenges and opportunities.
Which Speech Recognition Provider Is Best for You?
Determining the right replacement solution or provider when migrating off Nuance is a complicated decision. Your business will have unique challenges and circumstances. If you need to stay on-premises, then the decision is more straightforward as we offer several excellent alternatives.
