Waveform Communication, an Indiana-based IVR provider, has developed an algorithm that improves voice searches on computers and smartphones. The speech recognition software also helps people who wear hearing aids distinguish between similar sounding words.

The IVR algorithm is digital code based on a model of vowel perception and production derived from cues in visual displays. It is the first model that has demonstrated vowel perception at human performance levels. This technology, according to company officials, eliminates the flaws associated with current speech recognition technology available in the market.

The Waveform Model explains the complex cognitive process of vowel production and perceptual errors on the most fundamental level for the first time. The technology includes methods to improve speech in noise, speech recognition algorithm development, talker identification from waveforms, and improving hearing aids-- all are patent-pending.

"Some technology has only a 90 percent accuracy rate, which is unacceptable for the general public and professionals such as medical or court record transcriptionists," said Michael A. Stokes, the company's CEO and leader of the research, in a statement. "Some technology requires users to train on their voice or cannot recognize multiple speakers."

The company claims the technology can achieve 99.2 percent voice recognition accuracy and can be used by multiple speakers without special training. The technology finds applications in several scenarios including developing speech recognition apps in phones.

The technology has generated additional interest among students and researchers after the presentation of improved performance in 2011. The work will impact a number of technologies used every day and will continue to explain processes that have been studied for decades.

"Improved voice recognition systems in electronics may open up the world for people who cannot use or do not have access to a physical keyboard," Stokes said. "Reducing errors in reports with highly technical language may lead to better end results for researchers and the general public."

Waveform Communication, a startup located in the Purdue Research Park near Indianapolis International Airport, has secured $100,000 in funding from an Indiana-based venture capitalist in 2012. In 2011, the company also gained recognition as one of the top 50 startups in the world by the Ewing Marion Kauffman (News - Alert) Foundation in 2011.
