  • Method and Apparatus for Canceling a User's Voice
    Publication number: 20080118081
    Abstract: The disclosed system is designed to provide active noise cancellation to a user of an electronic device, such as a cellular device. For example, the system allows the user's voice to be transmitted via a cellular network, while at the same time canceling the user's voice externally. As a result, the system provides a user with a measure of privacy. The system may filter ambient noise before transmitting the user's voice. In addition, the system may store characteristics of a user's voice in order to better perform voice cancellation.
