1. A voice navigation device, comprising:
- a receiver, receiving more than one traffic condition message;
a voice-guidance-item priority weight data base, which is used to store a voice-guidance-item priority weight table including at least two groups of voice-guidance-item each having different priority weight, with each said voice-guidance-item group including more than one voice-guidance-item, said voice-guidance-item corresponds to said traffic condition message;
a voice-guidance-item broadcasting unit, which is used to obtain said voice-guidance-item to broadcast; and
a processor connected to the receiver, the voice-guidance-item priority weight data base, and the voice-guidance-item broadcasting unit, so that when said traffic condition message is received at said receiver, said processor is used to obtain the corresponding voice-guidance-item from the voice-guidance-item priority weight data base, which is provided to the voice-guidance-item broadcasting unit to broadcast; and
if another traffic condition message is received while the broadcasting of the original voice-guidance-item is still in progress, then another corresponding voice-guidance-item is obtained from said voice-guidance-item priority weight data base, and the priority weight of the original voice-guidance-item and that of the newly obtained voice-guidance-item are evaluated and compared, after the broadcasting of the voice-guidance-item having higher priority weight has finished, then the voice-guidance-item having lower priority weight is broadcasted.

Abstract
The voice navigation method relates to a voice navigation device and a voice navigation method, which may be utilized in cooperation with the Satellite Global Positioning System. The method is used to broadcast a voice-guidance-item having higher requirement importance more preferentially than a voice-guidance-item having low requirement importance, even if the voice-guidance-item having low requirement importance is obtained when the voice-guidance-item having high requirement importance is still in progress.

6. A voice navigation method, comprising the following steps:
-
(A) receiving a traffic condition message; (B) obtaining a voice-guidance-item corresponding to said traffic condition message; (C) broadcasting said voice-guidance-item; (D) receiving another traffic condition message while the broadcast of said voice-guidance-item is still in progress; (E) obtaining another voice-guidance-item corresponding to said another traffic condition message; (F) evaluating and comparing the priority weight of said voice-guidance-item and that of said another voice-guidance-item, classifying them into the voice-guidance-item having high priority weight and the voice-guidance-item having low priority weight; (G) broadcasting the voice-guidance-item having high priority weight until it has finished; and (H) broadcasting the voice-guidance-item having low priority weight. - View Dependent Claims (7, 8)
