Nuance Vocalizer


Your Complete Spoken Output Engine

Nuance Vocalizer is the complete spoken output engine that provides seamless conversations so you can tell your customers anything they need to hear. Built on a legacy of research and expertise, Vocalizer is used around the world in over 40 different languages. It handles all of your application’s audio, both from your library of static prompt recordings and by generating dynamic prompts using text-to-speech (TTS) technology. By providing your developers with a single source for all audio output, Vocalizer gracefully combines computer-generated and pre-recorded audio so you can automate more, improve your customers’ experience and reduce implementation and operational costs.

Avoid Unnecessary Transfers

Sometimes a caller needs to hear dynamic information that’s tough to pre-record with voice talent such as names, addresses or information from a database. Vocalizer’s text-to-speech capabilities can read back that information as part of an automated system, saving a transfer to an agent to complete the task.


Automate More Calls

Research has shown that callers are more likely to complete an automated call when they hear information such as names and addresses read clearly by a single voice. Callers who hear “patchwork prompts” of multiple voices with poorer quality text-to-speech are distracted by the mixed voices and are more likely to opt-out of automation.

Simplify Application Development

Today’s applications developers manually keep track of a confusing list of sound clips. With Vocalizer, you provide the text to read and Vocalizer pulls from your library of pre-recorded prompts to assemble the audio output. If Vocalizer can’t find a complete recording of the requested text, it generates high quality text-to-speech and blends it seamlessly with any partial prompts in your library.
