Abstract
In a portable communication device (104) that is able to operate in a speakerphone mode, a user interface such as a keypad (120) and display (122) are provided to allow the user to select (1104) an enhanced mode so that leading fricatives of speech are more likely to be detected as speech, and played over a speaker (214). Upon selecting the enhanced mode of operation, the voicing value of each frame of vocoded speech received is increased, thus making it more likely for energetic fricative frames to be detected as speech.
