I've just generated voice files for my sansa clip using the latest rbutility, and have noticed that some of the spoken phrases are difficult to understand.
The cause of this is that the strings that are passed to the speech synthesis contain technical / joined words, for example:
"Replaygain type"
"Idle Poweroff"
"Filesize"
"Cuesheet"
It's not clear to me if the source of the text for the speech is also used for displaying on the screen, but simply hyphenating words goes one massive step towards improving clarity, e.g:
"Idle Power-Off"
The absolute ultimate would be to put data into the file using something like ssml, so things like "A" would be pronounced correctly too.
