Nuance launches new text-to-speech engine

Computer generated voice to deliver information in applications and services

By CBR Staff Writer

Nuance Communications has expanded its line of speech software with the launch of Vocalizer 5, a new text-to-speech (TTS) engine for enterprise and mobile applications.

The company said that the TTS engine is used to provide a computer generated voice to deliver information in applications and services including automated customer service; voice readback; and turn-by-turn GPS directions.

Nuance claims that the new software offers enhanced accuracy to contact centres and enterprises’ automated systems by integrating text-to-speech with pre-recorded audio for conversations with the caller.

According to Naunce, the Vocalizer 5 includes: one source for all audio output; name and address playback; customisation to allow contact centres and enterprises to integrate their own recordings and tune existing voices; and support for about 41 global languages.

Nuance said that the new software also simplifies application development by allowing the developer with the tools for tuning and voice sculpting. It manages the static prompts, carrier prompts, and computer-generated speech through unified interface to deliver a flow of speech, free from clicks and latencies.

In addition to the new software, the company also offers Vocalizer 5 Basic for enterprise applications that require limited, small-set vocabularies, such as currency, date and time, and telephone numbers.

Dan Faulkner, VP for product management and marketing of enterprise division at Nuance, said: “With Vocalizer 5, contact centres can dispense with the overhead associated with managing static prompting and dynamic TTS independently, and can instead focus on the message their callers need to hear.”
