TTS included in NDRIVE v10 ?

Downloaded NDRIVE v10.2.10 (42 MB) and when I looked at the extracted files, I have noticed, that the only sound related files are in the VOICES folder, and they are very small ~5 Mb
Other GPS softwares are using LOQ about 80 Mb or NUA around 50 Mb folder sizes.
Does NDRIVE have real TTS ?
If it does, how is the voice quality ?

-----well, it looks like I have found the answer for my own question------

found a ndrive v10.2.10 in cyberspace, which has all the needed files to run TTL
it came with KARENENA.ZBI voice file, which is an Australian female voice
Then I did further search for *.zbi files on the web, only looked for larger *.zbi files around 9 MB...11 MB, and found SAMANTHAENU.ZBI file, which is an USA female voice file.
Also have seen a portugese TTL file on a brazilian webpage, but it is no use for me.
So I have now a fully working ndrive v10 with TTL and a selection of 2 english female voices.
