Latest Patents

Nussbaum's latest patents include innovative methods for operator interactions in developing phoneme recognition by neural networks. His automated speech recognition system converts speech signals into compact, coded representations that correlate to a speech phoneme set. The system employs various neural network pattern matching schemes to perform necessary speech coding. An integrated user interface is designed to assist users unfamiliar with speech recognition or neural networks, enabling them to quickly develop and test neural networks for phoneme recognition.

To train the neural network, digitized voice data containing known phonemes are processed through the user interface. The digitized speech is segmented into phonemes, with each segment labeled with a corresponding phoneme code. Based on user-selected transformation methods and parameters, each segment is transformed into a series of multidimensional vectors that represent the speech characteristics of that segment. These vectors are iteratively presented to the neural network to train it to consistently distinguish and recognize these vectors, assigning appropriate phoneme codes to each.

The system also allows for simultaneous display of the digitized speech, segments, vector sets, and a representation of the trained neural network. This visual confirmation aids users in verifying the acceptability of the phoneme training set. Users can audibly confirm the acceptability of the digitization scheme, segments, and transform vectors, ensuring satisfactory training data is presented to the neural network. If any step or parameter produces an unacceptable result, users can modify parameters and verify improvements in performance. The trained neural network is automatically tested by presenting a test speech signal to the user interface, allowing for both audible and visual confirmation of automatic segmentation, transformation into multidimensional vectors, and the resulting neural network assigned phoneme codes.
