Nexidia Pioneered the Field of Phonetic Speech Analytics

Nexidia’s roots in this field run deep, extending to original research at the Georgia Institute of Technology where the phonetic indexing and search approach was first developed as a superior alternative to the slow, inaccurate process of large vocabulary continuous speech recognition (speech-to-text). With the original inventor still on staff, and additional research scientists from places such as the Massachusetts Institute of Technology and Carnegie Mellon University, Nexidia continues to innovate and improve on its core intellectual property.
