when i am driving and my s3 is synced to my car's hands free bluetooth, i would like to have any text messages converted to speech so i can hear them thru the bluetooth. I want this for a traffic alert app(voice alerts) which i have just downloaded. the app can alert you of traffic problems ahead while you are driving. it can send you an email or text msg. i am aware of google text to speech, and samsung tts. any advantage of one over the other? or is there something better out there i am not aware of.
