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.

Claims

1. A voice navigation device, utilized in cooperation with a Satellite Global Positioning System, comprising:

a receiver, connected to the satellite global positioning system, to obtain more than one road-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 road 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 road 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 road 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.

2. The voice navigation device of claim 1, wherein the priority weight is classified according to the importance of driving requirements.

3. The voice navigation device of claim 1, wherein the processor further comprising:

a priority weight evaluation and comparison unit, which is used to evaluate and compare the priority weight of the original voice-guidance-item and that of the newly obtained said another voice-guidance-item.

4. The voice navigation device of in claim 1, wherein the processor further comprising:

a broadcast finish verification unit, which is used to verify the termination of the broadcast of the voice-guidance-item.

5. The voice navigation device of claim 1, wherein if said voice-guidance-item broadcasting unit has not finished broadcasting, and another road condition message from the receiver is received by said processor, then repeat the above-mentioned steps.

6. A voice navigation method, utilized in cooperation with a Satellite Global Positioning System, comprising the following steps:

(A) receiving a road condition message;

(B) obtaining a voice-guidance-item corresponding to said road condition message;

(C) broadcasting said voice-guidance-item;

(D) receiving another road condition message while the broadcast of said voice-guidance-item is still in progress;

(E) obtaining another voice-guidance-item corresponding to said another road 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.

7. The voice navigation method of claim 6, wherein said voice-guidance-item and said another voice-guidance-item are stored in the different groups of voice-guidance-items respectively.

8. The voice navigation method of claim 6, further comprising a step of verifying the termination of the process flow after step (H), and if the result of the verification is negative, then steps (D) to step (H) are repeated.
