  • Patent number: 10010288
    Abstract: Detection of neurological diseases such as Parkinson's disease can be accomplished through analyzing a subject's speech for acoustic measures based on human factor cepstral coefficients (HFCC). Upon receiving a speech sample from a subject, a signal analysis can be performed that includes identifying articulation range and articulation rate using HFCC and delta coefficients. A likelihood of Parkinson's disease, for example, can be determined based upon the identified articulation range and articulation rate of the speech.

  • Patent number: 9666181
    Abstract: A tuning system for tuning a speech recognition system includes a transmitter for sending a user response to a speech recognition system. The user response is based at least in part on a test stimulus that may be generated by the control system. A receiver receives a recognized response from the speech recognition system; this recognized response is based at least in part on the associated user response. An adjustment module adjusts at least one parameter of the speech recognition system based at least in part on at least one of the test stimulus, the associated user response, and the recognized response.

  • Patent number: 9553984
    Abstract: A method of tuning a hearing device includes sending a test signal to a model of a hearing device that may be remote from the actual hearing device being tuned. The test signal is encoded by the model and sent to the hearing device being tuned. The user of that hearing device sends a response signal based at least in part on the encoded test signal. This response is received and compared to the original test signal. Thereafter, an operational parameter is sent to the hearing device based on the comparison.

  • Patent number: 9319812
    Abstract: A method of assessing hearing characteristics of a subject is provided. The method includes determining a hearing capability of the subject based on responses of the subject to a series of sounds presented to the subject. Each sound corresponds to a presence, absence or irrelevance of a predetermined plurality of features. The method further includes assigning the subject to one of a predetermined plurality of classes based upon the responses of the subject, each of the plurality of classes being derived from hearing tests performed on a plurality of other subjects.

  • Patent number: 8788270
    Abstract: A method and apparatus for analyzing speech are provided. A method and apparatus for determining an emotion state of a speaker are provided, including providing an acoustic space having one or more dimensions, where each dimension corresponds to at least one baseline acoustic characteristic; receiving an utterance of speech by the speaker; measuring one or more acoustic characteristics of the utterance; comparing each of the measured acoustic characteristics to a corresponding baseline acoustic characteristic; and determining an emotion state of the speaker based on the comparison. An embodiment involves determining the emotion state of the speaker within one day of receiving the subject utterance of speech. An embodiment involves determining the emotion state of the speaker, where the emotion state of the speaker includes at least one magnitude along a corresponding at least one of the one or more dimensions within the acoustic space.

  • Patent number: 8784311
    Abstract: Systems and methods of screening for neurological and other diseases utilizing a subject's speech behavior are provided. According to one embodiment, a system is provided that includes an identification device used to determine a health state of a subject by receiving, as input to an interface of the device, one or more speech samples from the subject. The speech samples can be provided to the device by an intentional action of a user or passively due to the device being in the signal path of the subject's speech. The samples are communicated to a processor that identifies the acoustic measures of the samples and compares the acoustic measures of the samples with baseline acoustic measures stored in a memory of the device. The results of this determination can be communicated back to the subject or provided to a third party.

  • Publication number: 20120089396
    Abstract: A system that incorporates teachings of the present disclosure may include, for example, an interface for receiving an utterance of speech and converting the utterance into a speech signal, such as digital representation including a waveform and/or spectrum; and a processor for dividing the speech signal into segments and detecting the emotional information from speech. The system is designed by comparing the speech segments to a baseline to identify the emotion or emotions from the suprasegmental information (i.e., paralinguistic information) in speech, wherein the baseline is determined from acoustic characteristics of a plurality of emotion categories. Other embodiments are disclosed.
