  • Publication number: 20210313057
    Abstract: A wireless medical room control arrangement includes a wireless controller having a wireless router. A room identifier and a device identifier are stored in the controller. A communication interface sends commands to and receives commands from the wireless controller. In response to commands from the interface, the wireless controller sends wireless control signals to operate medical devices in the room. A room monitor adjacent a doorway provides room identifiers to medical devices and wireless controllers entering the room and provides dummy identifiers to medical devices and controllers exiting the room. The room monitors may connect to a global network processor that determines the location of the medical devices in a medical facility.

  • Patent number: 8443279
    Abstract: An image capture device in an endoscopic imaging system receives a video stream generated by an endoscopic video camera. In response to automatic recognition of a spoken utterance while the video stream is being received from the endoscopic video camera, the image capture device associates with the video stream an annotation that corresponds to the spoken utterance. The image capture device provides the video stream to a display device for display, such that the annotation can be overlaid on one or more frames of the video stream displayed on the display device.

  • Patent number: 7302389
    Abstract: A computer-based system generates alternative phonetic transcriptions for a target word or phrase corresponding to specific phonological processes that replace individual phonemes or clusters of two or more phonemes with replacement phonemes. The system compares a user's speech with a list of possible transcriptions that includes the base (i.e., correct) transcription of the test target as well as the different alternative transcriptions, to identify the transcription that best matches the user's. In a speech therapy application, the system identifies the phonological process(es), if any, associated with the user's speech and generates statistics over multiple test targets that can be used to diagnose the user's specific phonological disorders. The system can also be implemented in other contexts such as foreign language instruction and automated attendant applications to cover a wide variety and range of accents and/or phonological disorders.

  • Patent number: 7299188
    Abstract: A method and apparatus for generating a pronunciation score by receiving a user phrase intended to conform to a reference phrase and processing the user phrase in accordance with at least one of an articulation-scoring engine, a duration scoring engine and an intonation-scoring engine to derive thereby the pronunciation score. The scores provided by the various scoring engines are adapted to provide a visual and/or numerical feedback that provides information pertaining to correctness or incorrectness in one or more speech-features such as intonation, articulation, voicing, phoneme error and relative word duration. Such useful interactive feedback will allow a user to quickly identify the problem area and take remedial action in reciting “tutor” sentences or phrases.

  • Publication number: 20040243412
    Abstract: A computer-based automatic speech recognition (ASR) system generates a sequence of text material used to train the ASR system. The system compares the sequence of text material to inputs corresponding to a user's speech utterances of that text material in order to update the speech models (e.g., phoneme templates) used during normal ASR processing. The ASR system is able to generate a user-dependent sequence of text material for adapting the speech models, where at least some of the text material is based on the evaluation of previous user utterances. In this way, the system can be trained more efficiently by concentrating on particular speech models that are more problematic than others for the particular user (or group of users).
