Unit without text-to-speech (TTS): "Turn left 300 feet."
Unit with text-to-speech (TTS): "Turn left onto Adams Road in 300 feet."
In other words, TTS means the unit speaks the name of the road onto which an upcoming turn is to be made. This can be extremely handy in areas where there there may be multiple roads branching off and/or intersecting with each other within a short distance, since it lets you know onto which one of the 5 streets, roads, alleys, etc., you must turn, without requiring you to take your eyes off the road for a look at the GPS unit's screen.
TTS is not always perfect, in that it sometimes mispronounces a street name. Then again, so do I occasionally mispronounce a proper name. Almost always, however, TTS will pronounce a street name in a recognizable manner. For example, not far from me is "Shawan Road." It's pronounced like "Juan," but with the "sh" sound at the start of the word. One syllable.
Garmin units tend to pronounce it as "Shay Win" Road. This is wrong, but if you know there's a right turn coming up in 300 feet, and the unit tells you it's onto Shay Win Rd., and the sign says Shawan Rd., you'd have to be rather dim not to suspect that just maybe that's the road the unit's talking about.
Most of the time, the pronunciation of street names is accurate. I'd say 10% of the time, it's off a little. This figure is probably influenced to a considerable degree by the prevalence of exotic and/or foreign names in your area. Not that a street name has to be exotic or foreign to give the unit problems, but in general "Main Street" will be pronounced correctly just about 100% of the time. Whereas "Xichotkhma Street" might be mispronounced.
