Hi, We tried to do this for a set of professional business english training software suites for companies ages ago. We ended up using Microsoft Speech recognition with an External by Tuviah Snyder. On the the mac front we used the speech recognition ( then in Supercard) to see if any of the words reconized was in the restricted recognition target dictionary. Worked fine. However : If you are looking at precise comparisons of two phrases in the realm of : “ Flying aunts can be dangerous” “ Flying ants can be dangerous” then you need word-per-word FFT analysis and the closest I have come were the libraries to plot AIF files by Mark Smith, may he rest in peace. Stephen Barncard was so friendly to relay them to me in 2016. Then funding stopped and I had to pursuit other things. But I would be very interested in solving this as well, because it is a major asset when dealing with languages.( I’m an old linguist ;-) I believe Stephen would not mind the stacks being out there. I just can’t gauge if they would be any help in your endeavour.
