Without time travel, this is merely speculation & guesswork. Indeed, how 
far back in time would we need to go. This itself is controversial. I 
remember a time when it was confidently held by most that language was 
strictly a property of Homo sapiens. Now it is AFAIK generally held that 
Neanderthal man probably spoke (assuming that Neanderthal man is 'Homo 
neanderthalis' rather than 'Homo sapiens neanderthalis'), and it is now 
suggested that Homo erectus also used language.

There was a time, not so long ago, that one found it confidently stated 
that Neanderthals' anatomy did not allow them to produce speech 
(something to do with that there hyoid bone), and that their social 
structure were too primitive to need the use of speech. It is now known 
that there was no anatomical reason why Neanderthals could not have had 
speech similar to us moderns, and it is generally accepted that their 
social structures were likely to be developed enough so that language 
would be need, i.e. that Neanderthals are likely to have had language. 
See, for  example:

As for what sounds they would have had, you might like to take a look at:

As for possible Neanderthal phonologies (there is, of course, no reason 
to suppose that all Neanderthal groups spoke the same language any more 
that all members of Homo sapiens (sapiens) speak the same language), 
that surely is anyone's guess. If their vocal anatomy was not critically 
different from modern Man, then presumably their range of possible 
consonants & vowels was similar to our own.

As it is impossible to go very far back in time in our study of language 
(writing appeared only some 5000 years ago - and by reconstructing 
earlier languages like PIE we can perhaps go back another millennium, 
this leave long millennia for which, without time travel, we have no 
data. No such studies are possible.

However, studies have been made on the chronology by which infants 
acquire different sounds. See, for example

How relevant that is to Neanderthal phonologies, I don't know,

Aw - didn't PIE develop from Nostratic?    ;)

But somehow I don't think Neanderthals were speaking either PIE or 
Nostratic.
