First Claim
1. In a communication system that transmits text messages to mobile terminals, a mobile terminal comprising:
- a receiver that receives voice and text messages over an RF channel;
a text-to-speech (TTS) converter that employs a low complexity phonetic TTS algorithm;
a speech decoder;
a switch that operates to selectively provide decoded data to the TTS converter or the speech decoder, wherein decoded data comprising a text message is provided to the TTS converter and decoded data comprising voice data is provided to the speech decoder;
a controller that produces text menu messages; and
a speaker;
wherein audible messages corresponding to the text menu messages are generated and output to a user by the speaker.

Abstract
A mobile terminal includes a receiver for receiving text messages over an RF channel. The mobile terminal also includes a text-to-speech (TTS) converter that converts the transmitted text messages to an audible form. In this way, the present invention takes advantage of the reduced bandwidth required for transmitting text messages to provide an audible message to subscribers that use the mobile terminals. In an exemplary embodiment, the mobile terminal operates in a GSM communication system and receives text messages that are defined under short message service (SMS) protocol. Also, the TTS converter in the mobile terminal can be used to output the text menus of the mobile terminal'"'"'s interface in speech (voice) format.

3. A method for providing audible output of text messages in a communication system that transmits voice and text messages to mobile terminals, the method comprising:
-
receiving voice and text messages over an RF channel;
decoding a received message;
selectively providing the decoded data to a text-to-speech (TTS) converter or a speech decoder based on the decoded data, wherein decoded data comprising a text message is provided to the TTS converter and decoded data comprising voice data is provided to the speech decoder;
outputting the received message in audible form, wherein the TTS converter employs a low complexity phonetic TTS algorithm;
producing, by a controller within the mobile terminal, text menu messages;
generating, within the mobile terminal, audible messages corresponding to the text menu messages; and
outputting the audible text menu messages to the user. - View Dependent Claims (4, 5, 6, 7, 8, 9)
