DIGITAL CELLULAR TELEPHONE WITH VOICE FEEDBACK

摘要

A cellular radiotelephone (100) which uses voice feedback to announce which key of the keypad (155) has been depressed or to indicate the status of radiotelephone (100). The voice signals for the feedback are stored in memory (150) in a digitized and compressed format. The radiotelephone's speech CODEC (140) decompresses the appropriate digital signal. The CODEC (140) transforms the digital signal to an analog voice signal for use by the radiotelephone's audio output device.
