Latest Patents

One of his latest patents is titled "Automatic speech recognition with psychoacoustically-based feature extraction, using easily-tunable single-shape filters along logarithmic-frequency axis." This invention presents a method and apparatus for extracting speech features from a speech signal. The process involves converting linear frequency spectrum data into logarithmic frequency spectrum data, which is then processed using a series of digital auditory filters. These filters, while having a similar shape, are centered at different points on the logarithmic frequency scale, allowing for easy modification and tuning.

Another significant patent by Siohan is "Background model design for flexible and portable speaker verification systems." This invention simplifies the speaker verification process by utilizing a speaker-dependent background model. This approach eliminates the need for training data from other speakers and avoids the complexities associated with speaker-independent models. The system allows customers to select any password phrase in any language, enhancing its flexibility and usability.
