Are there any java wrappers available for Praat? If so, which is the best one in terms of speed and functionality? I ask this because the Praat scripts that I have written take far too long to execute over my entire dataset of several audio files, and I was therefore wondering whether there may be a java wrapper for Praat which would allow me to execute all the functions of Praat through Java in a shorter time.
I do not know of any Praat wrappers, neither for Java nor any other languages, as Praat itself was not written as a easily "wrappable" library. Most so-called wrappers are actually based on running scripts with praatcon, which will not save any time in your case.
What are the features you are interested in? There are many other feature extractors for speech and some of them are way faster than Praat.
Thank you Mr. Santos for your reply. I am currently interested in the basic audio features like MFCC, intensity, voice report features, etc. Just extracting only so much information is already taking me a lot of time. Later, of course I plan to extract more features or the same features over smaller intervals of time, etc. This means that it will take even more time for processing.
I'd recommend openSMILE then: http://opensmile.sourceforge.net/. There is a very complete manual (the openSMILE book) and many configuration examples included. It works a bit differently from Praat; instead of writing a script, you write a configuration file that describes the processing chain used to extract your features. There are blocks for all the features you described, so I believe you may find this tool useful. Feature extraction, in my experience, is very fast.
