Latest Patents

Shinoda holds a patent for a technique that adapts hidden Markov models for speech recognition. This patent, which is titled "Technique for adaptation of hidden Markov models for speech recognition," describes a system that learns the characteristics of a user's speech during a learning phase. The system collects adaptation data derived from the user's speech and its recognized results to enhance its performance. The parameters characterizing hidden Markov Models (HMMs) used in the system are modified based on this adaptation data. A hierarchical structure is defined in the HMM parameter space, which may take the form of a tree structure with multiple layers. Each node in this structure represents a subset of the HMM parameters and is associated with a probability measure derived from the adaptation data. This innovative approach allows for improved accuracy in speech recognition systems.
