[ gpsdrive ] No developer question, but a question about an older version of gpsdrive

Wed Oct 17 12:57:52 AKDT 2007

Hi all,

I use gpsdrive-2.10pre2 on a Toshiba Libretto CT100 (266 MHz, 64 MB RAM, 
4GB CF-Card as IDE) running with Slackware. I use autogenerated routes 
via maquest.de and convert the routes with a shellscript out of the 
webpage into a way-routename.txt and a way-routename.dsc for festival 
soundserver.

This combination works quite good, I have speech output with directions 
and streetnames at all waypoints, really cool.

There is only one fact I want to improve: Because of the slow processor, 
the speech output of the dsc-file is sometimes quite late. I mean the 
text comes near the waypoint and with the car the distance to the 
waypoint is too near to have time to react in the correct matter (turn 
left or right or change the highway).

I found a file "speechout.c" in the sources where I found some 
configuration about the speech output. But I cannot interprete the code 
in the right way.

Is there a possibility to change the behaviour of gpsdrive in the way 
that the speechoutput comes earlier, let me say about 1000 m on highways 
and about 300 m in cities. So that I have enough time to react in a save 
way!?

Any help is appreciated and I thank you for your efforts!

Thomas Schönhütl.

P. S.: I attach the file here ...
