Latest Patents
One of Nikhil's latest patents is titled "Speech signal bandwidth extension using cascaded neural networks." This innovative system enhances voice quality by performing bandwidth extension on narrowband speech signals, generating wideband speech signals with higher audio quality. For instance, it can extend a speech bandwidth from a narrowband signal of 4 kHz to a wideband signal of 8 kHz or higher. The system employs cascaded neural networks, including sub-pixel convolutional neural networks (CNNs), to achieve this enhancement. Another notable patent is the "Spectral smoothing method for noise reduction." This system is designed for low input-output latency noise reduction in the frequency domain. It utilizes a real-time noise reduction algorithm that processes a single-channel noisy acoustic signal frame by frame to estimate a gain function. The system effectively reduces distortion and provides clean speech output by applying a Savitzky-Golay filter to frequency bands.
