  • Patent number: 7222074
    Abstract: An arrangement is provided to achieve automated voice responding dialogue that is psycho-physical state sensitive. The input speech data from a user is used to detect the psycho-physical state of the user. Spoken words are then recognized from the input speech data based on the detected psycho-physical state of the user. The recognized words form a transcription which is then used to generate a voice response that is appropriate according to the transcription and the psycho-physical state of the user.

  • Patent number: 7072834
    Abstract: An arrangement is provided for an automatic speech recognition mechanism to adapt to an adverse acoustic environment. Some of the original training data, collected from an original acoustic environment, is played back in an adverse acoustic environment. The playback data is recorded in the adverse acoustic environment to generate recorded playback data. An existing speech model is then adapted with respect to the adverse acoustic environment based on the recorded playback data and/or the original training data.

  • Patent number: 7058575
    Abstract: An arrangement is provided for integrating graph decoder with keyword spotting to improve the robustness of speech recognition. When a graph decoder based speech recognition mechanism fails to recognize a word sequence from input speech data, a keyword based speech recognition mechanism is activated to recognize the word sequence based on a set of keywords that are detected from the input data.

  • Patent number: 6999932
    Abstract: A language independent, voice based user interface method includes receiving voice input data spoken by a user, identifying a language spoken by the user from the voice input data, converting the voice input data into a first text in the identified language by recognizing the user's speech in the voice input data based at least in part on the language identifier, parsing the first text to extract a keyword, and using the keyword as a command to an application. Further actions include receiving results to the command, converting the results into a second text in a natural language format according to the identified language, and rendering the second text for perception by the user.

  • Patent number: 6999931
    Abstract: A spoken dialog system using a best-fit language model and a spoken dialog system using best-fit grammar are disclosed. A spoken dialog system implementing both a best-fit language model and best-fit grammar is further disclosed. Regarding the language model, likelihood scores from a large vocabulary continuous speech recognition (“LVCSR”) module are used to select the best-fit language model among a general task language model and dialog-state dependent language models. Based on the chosen language model, a dialog manager can implement different strategies to improve general dialog performance and recognition accuracy. Regarding grammar, the best-fit grammar method improves performance and user experience of dialog systems by choosing the best-fit grammar among a general purpose grammar and dialog-state dependent sub-grammars. Based on the selected grammar pattern, the dialog system can choose from varying dialog strategies, resulting in an increase in user acceptance of spoken dialog systems.
