Latest Patents
One of Takahashi's latest patents focuses on speech recognition with text generation from portions of voice data preselected by manual-input commands. This invention allows a computer to read a voice speech recognition program from a first recording medium and voice data from a second recording medium. The CPU in the computer recognizes speech represented by the read voice data according to the speech recognition program, converting the result into text data for display. A check mark button enables the speaker to designate portions of voice data that should not be recognized, enhancing the accuracy of the speech recognition process. Additionally, the sound level of the voice portion is rated, and the gain of the voice data is adjusted accordingly.
Another notable patent is for a voice signal coding apparatus. This device includes a voice status detector that identifies whether an input signal is a voice or non-voice signal. It features a linear predictive analyzer that outputs parameters associated with the input signal, along with circuits for predicting both voice and non-voice sound sources. The switch controller selects the appropriate sound source based on the detection results, ensuring efficient processing of voice signals.
