Vocalizer - Text-to-Speech (TTS) technology for more personalised interactions.

Engaging customer support. No voice talent needed.

Vocalizer is a complete, enterprise-ready spoken text-to-speech output engine that enhances the IVR experience and enables more human, personalised customer interactions for less cost and hassle than hiring voice talent.

A new generation of technology

Creating audio output for the IVR and mobile apps can be complex and expensive. Nuance Vocalizer combines recordings with computer-generated speech to create the complete spoken output engine for any network-based text-to-speech (TTS) application.

Vocalizer is a new generation of text-to-speech technology that enables high-quality speech output by enriching the user experience with enhanced expressiveness, improved multilingual support and optimised readout of long text. Along with the ability to gracefully blend static and dynamic speech output, it features enhanced speech quality and accuracy thanks to optimised text processing, more comprehensive pronunciation dictionaries and, in many languages, complete voice refreshes.

Time saved is money saved

A 25% improvement of IVR call handling for a business with 24m calls a year leads to the elimination of 60,000 agent calls, which can equal a saving of nearly $300,000/yr. (2m calls per month at $5 per agent call).
