I for one would LOVE to try a spoken UI for an email client. My thinking has always been that compromising sacrificing plain english with a more strict/limited set of mnemonic keywords would introduce a learning curve but with a bigger payoff in reducing confusion.
Also emails delivered from this sort of interface need some means of indication that they were a spoken format, not typed such that the reader properly understands the context.
To me, a verbal UI seems attainable by lowering the bar of what we expect from the AI. Lower the need for AI to interpret your requests from general english to limited keywords. Allow for an adjustable vocabulary for spoken word recognition to accomodate a smaller dictionary with less mistypings. Make it clear the produced content is dictated and not hand-written quality
