I want to start this post by thanking Gnuite for making the changes to Maemo Mapper to allow this to be possible. I also want to point out that the only reason we did this is because alephito @ ITT asked me. He also helped with testing and tweaking the spanish voice…
Download and install Maemo Mapper
First of all you need to install Maemo Mapper version 2.5.2 you can get it here – > MAEMO-MAPPER
Download and install Festival
Now you need to install Festival which has Spanish voices and a flite shell script to use with maemo-mapper. I have two packages one contains only Spanish and one contains several other voices, I think US, British and Scottish and 1 female. The package containing more voices is larger.
> Festival with Spanish only < 4MB Dowload, 12MB uncompressed (8MB on flash)
OK, Now you have Maemo Mapper and Festival installed. Now we need to change the Route Download to get the directions in Spanish instead of English.
Open Maemo Mapper, Open Menu > Route > Download
Add “&tld=es” without the quotes
Now you will have Spanish text and it will use festival Spanish voice with maemo-mapper
Please review the thread on InternetTabletTalk.com for further information and other users experiences
On a side note another larger package exists also
> Festival with All Voices < 20MB Dowload, 50MB uncompressed (35MB on flash) (Defaults to American female voice)
