You know, most of those names wouldn't be an issue at all if you asked any non-English speaker.. Simply pronounce all the letters, as written.
(Well, maybe the French would have some questions too.. but I don't really know French)

I got this information from Akio Morita's autobiography.

Actually, of course, it was "sonny" that the name derives from, but since that's pronounced the same as "sunny" I used the latter to make the sound unambiguous.

As best as I could tell, "maemo" came out as "mah-eh-mo" from many Finnish speakers, with the "ah-eh" almost a diphthong (that is, almost sounding like one vowel and not two).

The "two-and-a-half-syllable" description someone used is pretty accurate, although now I'm inclined to suggest "two-and-a-quarter-syllable" as being even closer.

And "ah-eh" is pretty close to the "aa-ee" diphthong that comes out in American pronounciation as long i (eg, as in might). But "my-mo" isn't as close an approximation as I'd wish. Just closer than "may-mo."

Here is flite's opinion on the matter.

Can't get Festival to work. It whines about no /dev/dsp. However, festvox-suopuhe-common festvox-suopuhe-lj festvox-suopuhe-mv are the required suomi (Finnish) festvox packages.
