I like to say that there are (2) main categories of effort here, one
very do-able (a single voice), the other (infinite voices) plausibly
intractable atm.

This is possible, if only a few voices; that have had their speech patterns
analyzed, manipulated into storage with ample resources, then what you seek
is possible, accuracy is the constraint.

If you are after a solution that can work with any voice, even limited
to a single language, then the answer is a long way away. Some would say
intractable. There is the question of accuracy required and the complexity
of vocabulary, sentence structure and allowed nominal variation on the voice(s).

With google sized resources, you can masquerade the problem with templates
for many different voices, but the underlying problems abound without limit.
What you actually do is 'train' the google system to customize it's
translation of a given voice, very accurately over time.
Now say I disguise my voice with a throat infection, depressed attitude,
exuberance etc etc, you can see the troubles. In fact, the day after
watching horrible English cinema, which is often contagious (monty python
--life_of_bryan), I often develop a temporary 'Manchester slang' in the
vernacular. Endless, unlimited gyrations should one want to have a bit-o-fun
with language, particularly when any number of 'hill_billy' contaminants
manifest.
My mathematical belief is the problem is intractable, certainly as you
approach a high level of required accuracy. In fact folks routinely joust
with one anther around the 'looseness of language' and the various varieties
of layered meanings
Truly intractable, but a 'dumbed down' simile surely will exist at some
point. Google ibm in your searches as they did quite a bit of foundational
research in a variety of related areas of (speech/sound/voice) research.
Still, google's offering might prove acceptable for your needs.
