Latest Patents
Wittenstein holds a patent for a "Preprocessing system for speech recognition." This invention processes an independent body of speech during an enrollment process. It creates a set of speaker-specific enrollment parameters for normalizing analysis parameters, including the speaker's pitch and the frequency spectrum of the speech as a function of time. A particular objective of this invention is to ensure that these analysis parameters have the same meaning from speaker to speaker. After the pre-processing performed by this invention, the parameters would appear similar for the same word, regardless of the speaker. This innovation aims to reduce variations in the speech signal caused by the physical makeup of a speaker's throat, mouth, lips, teeth, and nasal cavity.
