RDS-TMC radio receiver including a speech segment memory

A module (47) for the processing of encoded messages derived from a radio signal, including a control circuit (64) for

• (a) delivering encoded messages, derived from a radio signal, to at least one storage device (28, 68),
• (b) receiving control data, derived from the encoded messages, from at least one storage device (28, 68), and
• (c) forming a speech text for an audio circuit (48) and a display text for a display device (61) from the control data,
• wherein the module comprises a speech segment memory (65), coupled to the control circuit (64), for storing speech segments of at least one language, and
• the control circuit is arranged to form a speech text corresponding to message parts for which speech segments are stored in the speech segment memory (65),
• characterized in that said speech segment memory stores only predetermined speech segments which are less than all the speech segments required to provide speech text for the entirety of all said messages, whereby, independent of language, at least one part of at least one of the encoded messages has no corresponding speech segment, said control circuit thereby being unable to form any speech text for said one part of said at least one of the encoded messages, and
• the control circuit is arranged to form a display text with at least all parts of the message which are not contained in the speech text and for which no speech segments are stored in the speech segment memory (65).
