there's one thing i've always hated in the S60 speech synthesizer when it pronounced names:

i'm living in austria and most of the people in my contacts database have names that work well with a german pronunciation. however, some people have french, turkish or croatian names that sound awful when the speech synthesizer is set to german.

it would be nice if some fure version (2.0, 3.0,... ) of espeakcaller could allow settings per number. like: you define all settings as you do now, but then you can add certain numbers to the espeakcaller-database and have distinct settings for each of these numbers. this would allow me to set the language differently for some callers, but it would also have the nice side effect that you could have other voices, different texts or maybe even no text at all for some of your contacts.
