His innovative work has advanced the capabilities of speech recognition systems, making them more efficient and effective.
Latest Patents
One of his latest patents focuses on a novel approach to speech recognition. This invention computes the log probabilities of the null and alternative hypotheses for an input speech sample by comparing it with specific stored speech vocabularies and general speech characteristics. The probabilities are normalized by the magnitude of the null hypothesis to derive a likelihood factor, which is then compared with a rejection threshold that depends on the length of the utterance. This method simplifies the high-order polynomial representation of the rejection threshold length dependency by using a series of piece-wise constants.
Another significant patent involves a technique for the selective use of Gaussian kernels and mixture components in speech recognition systems. This invention utilizes tied-mixture hidden Markov models (HMMs) to match phonemes of spoken words with the acoustic input. By reducing the number of Gaussian kernels considered in the state observation likelihoods (SOLs) computation, the invention enhances computational efficiency and memory access. Additionally, some mixture component weights are quantized to further improve memory space utilization.
