Title: The Innovations of Michael J Tomlinson
Introduction
Michael J Tomlinson is a notable inventor based in Malvern, GB. He has made significant contributions to the field of recognition systems, particularly in the area of speech signal processing. His innovative work has led to the development of a unique patent that addresses spectral distortion in speech recognition.
Latest Patents
Tomlinson holds a patent for a recognition system that incorporates a filterbank analyser. This system produces successive data vectors of energy values for twenty-six frequency intervals in a speech signal. A unit compensates for spectral distortion in each vector, allowing for improved accuracy in speech recognition. The compensated vectors undergo a transformation into feature vectors with twelve dimensions, which are then matched with hidden Markov model states in a computer. Each matched model state has a mean value that estimates the speech feature vector. A match inverter produces an estimate of the speech data vector in frequency space by a pseudo-inverse transformation. This includes information that will be lost in a later transformation to frequency space. The estimated data vector is compared with its associated speech signal data vector, and infinite impulse response filters average their difference with others. The averaged difference vectors are used by the unit in the compensation of speech signal data vectors.
