Abstract: Synthesizing speech sounds to express a short message received from a caller in a handset coupled to a hands free kit, includes handset circuitry for transferring an alarm signal to the hands free kit to generate an alarm to inform the user of the receipt of the short message, and for transferring the short message to the hands free kit when receiving a short message calling signal from the hands free kit. The short message calling signal is generated upon the detection of a predetermined voice command by the user indicating a desire to hear the short message. The hands free kit includes circuitry for synthesizing the speech sounds according to the short message received from the handset.

Abstract: The invention relates to a cellular phone terminal system, and in particular to a method for changing timbre of a voice signal during conversation in a cellular phone terminal system having a filter for filtering a PCM input signal. The method comprises the steps of: waiting for a timbre selector key input for a desired timbre when a timbre converter key is inputted during conversation; and setting a filter coefficient of the filter correspondingly to the timbre selector key input and filtering the PCM signal to change timbre.
