Title: E Veera Raghavendra: Innovator in Speech Synthesis Technology

Introduction

E Veera Raghavendra is a notable inventor based in Hyderabad, Telangana, India. He has made significant contributions to the field of speech synthesis technology, holding a total of 4 patents. His work focuses on improving the quality and accuracy of text-to-speech systems, which are increasingly important in various applications today.

Latest Patents

One of his latest patents is titled "Method for forming the excitation signal for a glottal pulse model based parametric speech synthesis system." This innovative system and method involve forming the excitation signal using multiple sub-band templates rather than a single one. The combination of these templates is dynamically adjusted based on determined energy coefficients that vary from frame to frame. These coefficients are learned during feature training and are appended to the feature vector, which includes spectral parameters modeled using Hidden Markov Models (HMMs).

Another significant patent is the "System and method for outlier identification to remove poor alignments in speech synthesis." This invention addresses the quality of output in text-to-speech systems, which relies heavily on accurate alignments of speech utterances. By identifying mis-alignments and mis-pronunciations through fundamental frequency methods and group delay-based outlier methods, the system enhances the synthesis quality by removing these outliers.
