  • SPEECH-BASED OPTIMIZATION OF DIGITAL HEARING DEVICES
    Publication number: 20070286350
    Abstract: A method of tuning a digital hearing device, such as a cellular phone, a mobile phone for communicating via a wireless ad hoc network, and a Voice-over-Internet-Protocol (VoIP) phone, can include playing portions of test audio, wherein each portion of test audio represents one or more distinctive features of speech. The method also can include receiving user responses to played portions of test audio heard through the digital hearing device and comparing the user responses with the portions of test audio. An operational parameter of the digital hearing device can be adjusted based on one or more of the distinctive features of speech that is associated with the operational parameter.
