IVONA BrightVoice and Rapid Voice Development (RVD) - technologies that create lifelike voices

State-of-the-Art

Ideally, Text-to-Speech voices should read texts out loud sounding just like humans. Unfortunately, despite recent improvements, most text-to-speech voices still have an artificial/synthetic sound and this lack of expressiveness makes them less appealing.

BrightVoice Brings A New Era for Text-to-Speech

IVONA Voices allow lifelike, expressive reading of words, sentences, paragraphs and even entire publications. BrightVoice technology uses artificial intelligence algorithms, which reflect the expression and individual characteristics of the human voice. As a result, the synthesized speech is virtually indistinguishable from the professional voice-over recording. BrightVoice is a result of 10 years of research.

IVONA Text-to-Speech takes advantage of many other technological innovations that make it a revolutionary system in the TTS industry. Since 2006, IVONA has maintained a leading position in the prestigious annual scientific event Blizzard Challenge (comparison of Text-to-Speech systems).

Rapid Voice Development: Fast building of IVONA Voices

RVD technology (Rapid Voice Development) makes the process of building IVONA Voices fast and relatively inexpensive. It uses a set of tools modeling linguistic characteristics such as subvocalization, accentuation and intonation. It also allows to efficiently, quickly and accurately detect the speech signal in original speech recordings.

IVONA voices with BrightVoice technology: New quality in unique lifelike voices

  • BrightVoice technology guarantees a smooth natural speech
  • New language models provide intelligent text interpretation
  • Up to 10 times faster speech generation
