Latest Patents

One of Waibel's latest patents is titled "Systems and methods for training statistical speech translation systems from speech utilizing a universal speech recognizer." This invention outlines an iterative language translation system that includes an automatic speech recognition component designed to recognize spoken language in a source language and create a source language hypothesis. Additionally, it features a machine translation component that translates the source language hypothesis into a target language. The system also incorporates a second universal automatic speech recognition component that recognizes spoken languages in multiple target languages and creates a target language hypothesis. This comprehensive system adapts both the speech recognition and machine translation components to improve accuracy and efficiency.

Another notable patent is "Attribute-based word modeling," which describes an attribute-based speech recognition system. This system utilizes a speech pre-processor to produce a sequence of acoustic observations from input speech. It employs a database of context-dependent acoustic models that characterize the probability of sound sequences producing the observed acoustic data. The system includes a finite state language model and a one-pass decoder that compares the acoustic observations to the models, ultimately outputting a word sequence representative of the input speech.
