I downloaded the free app called Ivona text to speech. The voices are free to download while it's in beta so act fast. I changed the tts settings in my phone to Ivona and Google maps is using the voice from it. Much better voice than what Google had in there. Make sure you force stop Google maps or restart your phone to get the changes made.
