I'm mystified how the synthesized speech works on these GPS's. If I put in the name of a street not originally in the map program the voice still knows how to say the street name. Anyone have any info on how this is accomplished?
Nope, but it works the same way as other programs, such as cell phones, websites, etc where you have tts. I am guessing it works the same way.
I'm stii mystified but am amazed at how well text to speech works on these Garmin units.
Yeah, works pretty darn well.
Anyone have any info on how this is accomplished?
See http://www.nuance.com/automotive/ I believe these are the folk who supply the TTS engine to Garmin.
The non TTS voices use about a hundred different sound files, (words or phrases) and are put together when appropriate. The TTS voices have thousands of sound files, and are put together when appropriate, I agree they do an amazing job, but I'm sure you've noticed quite a few mispronunciations. It is especially noticable in the West/SW where there are so many Spanish Street names. Also sometimes they kind of choke on a letter combination that is unusual.(Aussey Karen has a heck of a time with the rd combination in San Ardo)
