I've played around with it. I'm certainly NOT and expert but I'm pretty shur yu do NOT need a sound card. Sphinx will be happy to read an audio recording from a file. You can train Sphinx on a vocabulary and you can change the vocabulary database at any time. So if you ask a "YES/NO" question you first load the "YES/NO" database. So if you train the vocabulary database to only include reasonable responces you can do well. One other very powerfull feaure is that Sphinx can return a set of the most probable matches. Say you ask the user "when would you like to leave?" and Sphinx returns (0.50 cow, 0.45 now, 0.05 brow) Now you can use external software (your aplication) to scan the list for words that make sense in the context of your question. Clearly that would be "now", not "cow" For best work you ALWAS want a propability list and not just it's best guess. Research shows that humans do just that. We use context and grammer more then you'd think. That's why we tend to hear what we are expecting and automatically ask people to repeat if they way something totaly unexpected. That said yu need good audio quality. no speech recognition system is good if there is noise on the line As for language, Spinx doesn't know or care if you speeak spanish or Korean it's all just sounds, numbers and symbol strings. Spinx does not _understand_ anything. Spinx would work fine for a dial by name system but you would have to plan for the case where it can not find a match or finds more then one match. ASking the user to say both first and last anems may help. But poor audio quality is the #1 problem and 8Khz sampled "telephone quality" is at the low end of what will work.. You'd prefer 16 bit samples and 48Khz sample rate and a first quality mic. > > Before I continue and try it with an audio board; > - does sphinx really need an audio interface ? > - what is the quality like ? > - will it work in international environments ? > > I was doing a customer installation of Cisco's IPCC express with > Nuance ASR > and TTS.
