Text-to-Speech voices are intended to read texts naturally in a human-sounding way. Unfortunately, in spite of the many improvements TTS technology has made over the past few years, Text-to-Speech voices still have an artificial/synthetic sound, as the lack of expressiveness makes them less appealing. This normally makes listening to a text longer than a short sentence read aloud by a TTS voice quite difficult.
IVONA Voices with BrightVoice provide lifelike, expressive reading of words, sentences, paragraphs and even entire speeches and books.
BrightVoice technology uses artificial intelligence algorithms, which with computer precision reflects the expression and any individual characteristics of the human voice.
As a result, the synthesized speech is virtually indistinguishable from the professional voiceover recording. BrightVoice is a result of 10 years of research in IVONA Text-to-Speech.
IVONA Text-to-Speech takes advantage of many other technological innovations that make it a leading 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).
RVD technology (Rapid Voice Development) makes the process of building IVONA Voices fast and relatively cheap. It uses a set of tools modeling a linguistic issues such as subvocalization, accentuation, intonation. It also allows to efficiently, quickly and accurately determine the speech signal in original speech recordings.
Our first voices created with BrightVoice technology are Brithish English voices: Amy, Emma and Brian and American English voices: Kendra, Kimberly and Joey.
The British English voices were created in partnership with Royal National Institute of Blind People (RNIB), UK. Steve Tyler, Head of Innovation at RNIB says, "IVONA Software has delivered amazing quality and innovation in an area that we are particularly keen to support. We are proud to have met the team at IVO, who have worked extremely hard to help us achieve our goals. Their focus on quality shows in every aspect of our partnership.".
The American English voices were created in partnership with one of the most famous recording studios GMVoices, USA.
