What will be the recommended voice application for O2 XDA II to be able to read, reply, delete emails for a car while driving scenario?

i've tried Fonix VoiceCentral 2 and it works really well on PPC2003 but badly on Windows Mobile 2003 for Pocket PC phone ed. After installation onto an i-mate PDA2, it gives a warning that says voicecentral might not work. I was able to start the app but the voice from the PDA2 is crackling and unclear. I think it might be hardware incompatibility. The next time the app is started again, it fails to understand any of my commands. Anyone tested this on an O2 XDA II?

www.equivox.uk.com exist but none of the emails work. Does the company still exist? Where can i get a new version of VOXit Mailer for trial? I'm very keen to test this software as it is compatible with O2 XDA (as claimed in their borchure)

MS Voice Command 1.5 has "Read emails" command but not as robust as the Fonix VoiceCentral 2 Or wasn't working at all. Got the perception that it works from http://www.windowsitpro.com/Windows/Article/ArticleID/43504/43504.html


Any other recommendations? I'm keen to trial any other voice apps that serves emails. Thanks you :)
