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.
