Speech Discrimination Based on Multiscale Spectro-Temporal Modulations (ISR IP)

ISR intellectual property available to license

Inventors
Nima Mesgarani, Shihab Shamma

U.S. Patent: 7,505,902

Description
Researchers at the University of Maryland have developed a content-based audio classification algorithm based on novel multiscale spectro-temporal modulation features inspired by cortical processing.

A potential use for the classification system is to discriminate speech from non-speech. Non-speech, for example, could consist of animal vocalizations, music, or environmental sounds. In head-to-head comparisons with two other state-of the-art approaches to discriminating between speech and non-speech, the multiscale spectro-temporal system performed significantly better.

These algorithms also have applications in audio and data retrieval, archival management, modern human-computer interfaces, and in the entertainment and security industries. The researchers are also working on developing algorithms to enhance speech in noisy environments using an auditory model.
