Latest Patents
One of his latest patents is titled "Obfuscated Speech Synthesis." This invention relates to a method for synthesizing a speech signal by obtaining a speech sequence input signal that contains semantic content corresponding to a speaker's utterance. The process involves analyzing the input speech sequence to obtain a first sequence of feature vectors, synthesizing a second sequence of feature vectors based on the first, generating an excitation signal, and filtering it to produce a synthesized speech signal with obfuscated semantic content.
Another notable patent is "Speaker Recognition from Telephone Calls." This invention outlines a method for recognizing speakers by obtaining and storing speaker information for at least one target speaker. It involves collecting speech samples from telephone calls, classifying these samples, extracting speaker information, and comparing it with stored data to determine if an unknown speaker matches the target speaker.
