Re: Do phonemes = sounds?

So what's "the truth" here? Can computers create and/or recognise phomemes .. or is the notation too abstract?

I think if you take a pragmatic definition of a phoneme as something
that is used
in a pronunciation dictionary, then it is pretty clear that speech
recognisers can
recognise phonemes.  However they do so not by recognising elementary
but by finding the word which best explains the input acoustic signal.
And they do
that using the dictionary sequence of phonemes for the word and a set of
models which estimate the probability of different acoustic realisations
of those
phonemes. So it is only after the word is recognised that the system
knows which
phonemes it has recognised.

Sorry, that came out more technical than I'd hoped ...
