It was moderately difficult. The biggest item was creating the word
dictionary or corpus
Ahh, yes. Now I remember. This wasn't only tedious, it also made the
whole sphinx a fata morgana. I had thought it were a real speech-to-text
solution, not a text sample recognition program. I instantly lost interest,
but I still have it here. :-)
At one time there was a program accessed on their website to create a
dictionary. You fed it a text file of (words) as unary, di, or trigrahs
and it created the LM and other phonetic files you could then download
and install. That seems to have disappeared from the website or moved
and I can't find it.
On my system it would create a text string; e.g. "London Center, Delta
245 at Flight Level three three zero", pass it over the net to a text
parser inside an AI controller (I use the word AI loosely here), which
would formulate a response, create a text string, something like, "Delta
245, London Center , go ahead with your request" and pass it on to festival.
Nice for demos, but not very practical for any useful work until a
smarter controller was designed and built. Just one more item to add to
an already long. long list of nice todo's...
