  • Patent number: 8046229
    Abstract: The present invention is a server-side method and apparatus that enables visually-impaired users to navigate websites and hear high-quality streaming audio of narration and descriptions of each website. The system involves creating an audible website corresponding to an original website by utilizing voice talent to read and describe web content and create audio files for each section within an original website, then assigning a hierarchy and navigation system based on the original website design. To implement the system, a small program is installed on the home page of an original website which plays a tone upon a user's visit indicating that the website is accessible with the present invention. Upon hearing the tone, a user presses a key on the keyboard to exit the original website and enter the audible website. Audible narration is played through the user's computer, reading text and describing non-text information.

  • Patent number: 8024192
    Abstract: A technique is described for use in a decoder configured to decode a series of frames representing an encoded audio signal. The technique is for transitioning between a lost frame and one or more received frames following the lost frame in the series of frames. In accordance with the technique, an output audio signal associated with the lost frame is synthesized. An extrapolated signal is generated based on the synthesized output audio signal. A time lag is calculated between the extrapolated signal and a decoded audio signal associated with the received frame(s), wherein the time lag represents a phase difference between the extrapolated signal and the decoded audio signal. The decoded audio signal is time-warped based on the time lag, wherein time-warping the decoded audio signal comprises stretching or shrinking the decoded audio signal in the time domain.

  • Patent number: 8005678
    Abstract: A technique is described herein for updating a state of a decoder configured to decode a series of frames representing an encoded audio signal. In accordance with the technique, an output audio signal associated with a lost frame in the series of frames is synthesized. The decoder state is set to align with the synthesized output audio signal at a frame boundary. An extrapolated signal is generated based on the synthesized output audio signal. A time lag is calculated between the extrapolated signal and a decoded audio signal associated with a first received frame after the lost frame in the series of frames, wherein the time lag represents a phase difference between the extrapolated signal and the decoded audio signal. The decoder state is then reset based on the time lag.

  • Patent number: 8000958
    Abstract: The device and method of the present invention improves electronic communication which have behavioral consequences, including for example, flight communication, two-way closed circuit communication such as for fire, police, miners, scuba divers and other heath and safety workers, and even for mobile communication which happens during activities such as cellular or mobile conversations during driving. Dichotic listening techniques are altered to enhance dyadic (involving two people) interactions with a partner. The speech of at least the first member of the dyad is filtered to isolate the component below 0.5 Khz, which will be input with a gain to the left ear of the second person (provided that they are right-handed), and thus their right cerebral hemispheres, and the component with a frequency above 0.5 Khz. will be input to their right ears, and thus their left cerebral hemispheres.
