Latest Patents

One of his latest patents is titled "Formant tracking based on phoneme information." This invention presents a method and system for selecting formant trajectories based on input speech and corresponding text data. The process involves analyzing input speech to obtain formant candidates for specific time frames. The corresponding text data is converted into a sequence of phonemes, which are then time-aligned with the input speech. Nominal formant frequencies are assigned to each phoneme's center timing point, and target formant trajectories are generated by interpolating these frequencies. The system selects the closest formant candidates based on a minimum cost factor, which are then output for storage or further processing in subsequent speech applications.

Another significant patent is "Speech synthesizer having an acoustic element database." This method employs an acoustic element database established from phonetic sequences within a speech signal. The database is created by determining trajectories for each phonetic sequence and identifying a tolerance region based on the concentration of these trajectories. Acoustic elements are formed from portions of the phonetic sequences, minimizing perceptible discontinuities at junction phonemes. The invention also discloses computationally simple and fast methods for determining the tolerance region.
