I may be a bit dense here; the only voices I can find on the Garmin site that match the RealSpeak voices are for a StreetPilot
2730. The voices I can find for the Nuvi
are obviously not the ones I want, since they have names like "Squirrely".
On a whim, I downloaded the Daniel voice for the 2730 and extracted the files. Besides being for a Windows-based device, the sampling rate is 16Khz, while the Kindle voices are 22KHz. This wouldn't normally be a problem, except that the Kindle seems to only support 22KHz voices. On the plus side, the Tom and Daniel DAT files have identical structures, so they should be compatible.
If you could post a link to the Nuvi voices, I'd be appreciative.
