Latest Patents
One of Tung-Hui Chiang's latest patents is titled "Apparatus and method for portable dialogue management using a hierarchical task description table." This invention involves a portable dialogue management system that includes a dialogue manager and a hierarchical task description table. The hierarchical task description table consists of multiple base tables connected in a hierarchical structure. Each base table defines the strategy of a sub-dialogue and stores various dialogue states, domain parameters, and response actions corresponding to each dialogue state. The dialogue manager effectively manages the dialogue state of the system, determining the appropriate response action based on the current dialogue state. This system's design allows for easy portability across different applications, making it versatile and efficient.
Another significant patent is "On-line background noise adaptation of parallel model combination HMM with discriminative learning using weighted HMM for noisy speech recognition." This invention focuses on adaptively generating a composite noisy speech model to enhance speech processing in nonstationary environments. The system comprises a speech recognizer, re-estimation circuit, combiner circuit, classifier circuit, and discrimination circuit. It effectively generates a current noise model by aligning input utterances with noisy states and re-estimating the model parameters to improve recognition accuracy. This innovative approach significantly enhances the performance of speech recognition systems in challenging acoustic conditions.
