Latest Patents
One of Rajeev Nongpiur's latest patents is titled "Improving Speech Intelligibility Utilizing an Articulation Index." This invention models background noise from an input signal that includes both desired and undesired signals. The process involves generating a signal-to-noise ratio and an articulation index for the processed signals. Additionally, a spectrum of a speech segment is created to enhance intelligibility and quality based on the articulation index. The invention also includes shaping logic that adjusts the spectrum according to predetermined thresholds, taking into account the tilt of the background noise.
Another notable patent is "Speech Enhancement Through Partial Speech Reconstruction." This system improves speech intelligibility by reconstructing speech segments. It features a low-frequency reconstruction controller that selects a specific portion of a time domain signal while blocking signals outside this range. A harmonic generator produces low-frequency harmonics, and a gain controller adjusts these harmonics to match the original input signal's strength.
