gh's MathSpeak(TM) Finds Its "Voice" With Pittsburgh Speech Synthesis Company

gh LLC has chosen Cepstral LLC to give its MathSpeak(TM) assistive software technology a high-quality synthetic voice.

When used in conjunction with a Digital Talking Book -- such as the gh PLAYER™ -- MathSpeak™ can render mathematics and science both orally and visually. The software enables print disabled people to assimilate complex mathematical and scientific formulas and prevents the confusion that arises from equations that have multiple non-visual variations.

"Ease of listening has been shown to have a huge impact on one's ability to learn and, therefore, voice quality directly affects the success of our software as a math and science learning tool," said David Schleppenbach, gh LLC's founder and CEO. "Cepstral's state-of-the-art Text-To-Speech (TTS) engine and voice technology helps our MathSpeak™ software talk more like a real human voice, making it easier to understand and promoting retention of the material."

Students with print disabilities, the majority of whom are visually disabled, have struggled for years to gain access to instructional materials in the fields of science, engineering, mathematics and technology. Human readers have been necessary to level the educational playing field for these students, but this strategy has not provided them with true access. "A spoken math equation that is read aloud can be interpreted to be one of several different equations," said Schleppenbach. "With MathML, that ambiguity is removed."

"MathML is an exciting development, from both a social and intellectual standpoint," said Kevin Lenzo, CEO and co-founder of Cepstral. "Through our collaboration, the spoken delivery of mathematical formulas and equations, in a clear, unambiguous form can help people throughout the world work with advanced mathematical concepts and materials. We're proud to be designing voices and working with gh in such a rich and rewarding area."

MathSpeak™ is software technology developed by gh in collaboration with Purdue University and with support from the Indiana 21st Century Research and Technology Fund.
