Title: Luciano Nebbia: Innovator in Speech Synthesis and Echo Cancellation
Introduction
Luciano Nebbia is a notable inventor based in Turin, Italy. He has made significant contributions to the fields of speech synthesis and echo cancellation, holding a total of 4 patents. His innovative methods have advanced the technology used in communication systems.
Latest Patents
One of Nebbia's latest patents is a method of speech synthesis that focuses on preserving the fundamental information of the original signal while altering the remaining parts. This approach not only reduces processing time but also enhances the natural sound of the synthetic signal. The method involves subdividing waveforms associated with voiced sounds into intervals that correspond to the vocal duct's responses to excitation impulses. Each interval undergoes a weighting process, and the synthesis is achieved by overlapping and adding the shifted signals. Another significant patent is a method and device for the digital cancellation of echo. This method utilizes transversal adaptive digital filtering techniques to estimate the echo-channel pulse response. It subdivides the pulse response into three intervals, focusing on the significant portion to effectively copy the echo-signal.
