Android v1.1.5. I've been trying the American voice "Carly" It's generally very good. I noticed one anomaly, when approaching a freeway exit the voice said to take the "highway ramp." While I understood I've never heard that terminology. We normally say "off ramp" or "exit" to leave a controlled roadway and "on ramp" to enter a controlled roadway. I guess this is more of a report than a feature request.
Also, can MapFactor make use of the phone's built in synthesized voice? If so, would that allow it to add things like road names?
