Latest Patents

Ostendorf's latest patents include the following groundbreaking inventions:

1. **Multiple-action computational model training and operation** - This innovative processing unit is designed to determine a first feature value corresponding to a session by utilizing a first network computational model (NCM). By operating this model based on session information, the processing unit can determine respective second feature values corresponding to various actions through a second NCM, which uses a common set of parameters. This invention allows the selection of a first action from a plurality of actions based on expectation values derived from the first and second feature values.

2. **Relative semantic confidence measure for error detection in ASR** - This apparatus calculates a confidence measure for a target word string specified in a recognition result. It features an alternative candidate generator that produces alternative word strings, a classifier training unit for distinguishing between the target and alternative strings, and a feature extractor that represents the adjacent context of the target word. The confidence measure calculator evaluates the accuracy of the target word string, enhancing error detection in speech recognition systems.
