Abstract:
A mobile communication device (100) includes a vocoder (104) for vocoding speech (500) received at the mobile communication device. The parameters output by the vocoder are used to generate a voicing quality metric (208). The voicing quality metric is used to provide feedback to the user of the mobile communication device by various feedback modalities including visual (114), audible (108), and tactile modalities (118) to indicate when the user should speak louder to overcome ambient noise. The voicing quality metric is also used by other communications equipment (304, 312) to decide if communication activity is needed.
Abstract:
A voice reply system (200) suitable for handling an incoming call. The voice reply system can include a reply handler (220) that, responsive to receiving the first spoken utterance from a user (250) speaking into a headset (110), audibly provides to the user a caller identifier sound token correlating to the incoming call. The voice reply system also can include a call handler (210) that, responsive to the reply handler receiving a second spoken utterance from the user, implements at least one routine that handles the incoming call. For example, the routine can automatically provide a predetermined reply to a caller (240). The reply handler also can include a voice recorder (226) that can append a voice note onto the predetermined reply to provide a combined reply to the caller.
Abstract:
The invention concerns a method (400) and system (100) for bandwidth extension of voice for improving the quality of voice in a communication system. The method can include the steps of receiving (412) an unknown voice signal (105), identifying (414) the voice bandwidth (625) of the received unknown voice signal and establishing (418) a region of support (636) in view of the spectral content of the received voice signal. The method can further include the step of selecting (428) a combination of mapping databases (210, 212, 214) from a plurality of mapping databases. Each mapping database can be associated with a predetermined bandwidth extension range for extending the voice bandwidth.
Abstract:
A method (400, 600) and apparatus (500, 800) allow adjusting parameters associated with an audio signal output from a device. Tones are output according to a first interactive test profile presented on a user interface during a first test period. A first interaction forms a first adjustment profile with adjustment levels. The audio signal is output with parameters adjusted according to the first adjustment profile. The audio signal is output from the device in accordance with the first adjustment profile and a second interactive test profile. An interaction with the user interface forms a second adjustment profile having second adjustment levels and the audio signal is then adjusted in accordance with the second adjustment levels. The second interactive test profile includes a speech sample and an intelligibility parameter including a spectral tilt for the device and a formant sharpening profile.
Abstract:
The invention concerns a method (300) and system (100) for improving voice quality of a vocoder (138, 158). The method includes the steps of monitoring (312) a pitch of a voice signal (400) at a transmitting unit (110); when the pitch of the voice signal reaches a predetermined threshold (840), shifting (326) the pitch of the voice signal to at least a portion of a predetermined range (810); transmitting (338) the pitch-shifted voice signal to a receiving unit (112); and at the receiving unit, reshifting (342) the pitch-shifted voice signal to a level that compensates the step of shifting the pitch of the voice signal at the transmitting unit.
Abstract:
A method for using an earpiece (800) in a work environment is provided. The earpiece (800) attenuates sound from the work environment to the user's ear. The earpiece (800) includes an ear canal microphone (820) for measuring a sound pressure level in an ear canal of the user. Sound pressure levels are measured periodically while in the work environment. Each measured sound pressure levels is stored in memory (127) of the earpiece with time and location information. The sound pressure level information is downloaded to a database (1704) when the earpiece is removed from the user ear for recharging. The sound pressure level information is analyzed and any potential noise compliance issues in the work environment are identified.
Abstract:
At least one embodiment is directed toward one or more disposable devices suitable for use in a surgical field of an operating room. One device includes a sensor communicatively coupled to a wand to register points of interest on a first or second bone of a muscular-skeletal system and transmits location data related to the points of interest to the sensor to assess orthopedic alignment with the points of interest.
Abstract:
An earpiece (100) and acoustic management module for in-ear canal suppression control are provided. A method for suppressing signals for a conference call, a vehicle, and a general communication event is also provided. The earpiece can include an Ambient Sound Microphone (111) to capture ambient sound, an Ear Canal Receiver (125) to deliver audio content to an ear canal, an Ear Canal Microphone (123) configured to capture internal sound, and a processor (121). The processor can generate a voice activity level (622) and suppress an echo, spoken voice, and media content in the electronic internal signal, and mix an electronic ambient signal with an electronic internal signal in a ratio dependent on the voice activity level and a background noise level to produce a mixed signal (323) that is delivered to the ear canal (131).
Abstract:
At least one exemplary embodiment is directed to a method and device for voice operated control with learning. The method can include measuring a first sound received from a first microphone, measuring a second sound received from a second microphone, detecting a spoken voice based on an analysis of measurements taken at the first and second microphone, learning from the analysis when the user is speaking and a speaking level in noisy environments, training a decision unit from the learning to be robust to a detection of the spoken voice in the noisy environments, mixing the first sound and the second sound to produce a mixed signal, and controlling the production of the mixed signal based on the learning of one or more aspects of the spoken voice and ambient sounds in the noisy environments.
Abstract:
A method of calibration and a calibration machine is provided for calibrating sensory controls of an ultrasonic navigation system. It can include an enclosure for containing a paired device group to minimize air flow therein, one or more holder mechanisms for rigidly mounting the paired devices at specific and adjustable orientations, and a rail system for holding the one or more holder mechanisms at specific locations within the enclosure. A computer communicatively coupled to the calibration machine can precisely adjust actuators for configuring the distances and orientations of the holding mechanisms and control a transmission and reception of the paired devices for calibrating the paired devices.
