Title: Innovations by Inventor Fernando Villavicencio

Introduction

Fernando Villavicencio, an accomplished inventor based in South Pasadena, CA, has significantly contributed to the realm of voice technologies. With three patents to his credit, Villavicencio's innovations focus primarily on enhancing the quality of text-to-speech and singing voice generation.

Latest Patents

His latest patent, "Enhanced virtual singers generation by incorporating singing dynamics to personalized text-to-speech-to-singing," reveals a groundbreaking technique to improve Text-to-Speech (TTS) based singing. This invention preserves the speaker's identity while enhancing sound quality by integrating speaker-independent natural singing information into the Speech-to-Singing (STS) framework. The Template-based Text-to-Singing (TTTS) system effectively merges characteristics derived from TTS and actual singers, represented by Mel-generalized cepstrum (MGC) coefficients. The innovative process involves combining low-order MGC coefficients from TTS-generated singing voices with high-order MGC coefficients from real singers, yielding a more refined audio output.

Another notable patent, "Global frequency-warping transformation estimation for voice timbre approximation," outlines a systematic approach to converting a source voice into a target voice. This method includes recording both source and target voice data, extracting spectral envelope features, and aligning frames for conversion into the frequency domain. The end result is a digital waveform that delivers target speech to users, showcasing a significant advancement in voice technology.
