Or you could create a listener that monitors the level of microphone input being generated, appends information into a 2d array (length of trace and height at a given second).
Once the data is collected you would be able to analyze sections of the newly stored array, against previously stored phrases... E.G. there is no activity and then suddenly the user says "on", this takes around a second for the given user to say, and then silence once more... now the listener captures the data and places it in an array, the array is then sequenced to discover all the drops and peaks in the user's speech pattern... analysis is then preformed to find the time it takes for a bell curve to raise hit plateau and then finally drop, and then compare the data to a stored letter, word, or phrase; all done over several points of comparison, and allowing for a little variation as to the placement along the curve (or place within the array). Not only the peaks are important... you must also analyze the transition between peaks and drops/valleys. So "o" started at -20 db a given amount of time later it raised to -12db, and then dropped to -16 where it proceeded to transition into "n" at -17, -19, -22, and then raised a given amount of time later to -14 etc. (for more accurate software you would of course need more point comparisons) If I were you I would look at the way it is done by scratch; for it will help advance your programming ability in flash greatly. AS 2.0 is quite similar to c++ in a lot of respects. Your project is definitely possible at flashes current state. There was actually a program I saw that utilized peaks and valleys in sound to play a game. If anyone has more helpful information to add, or if my way of doing it is too complex, I would love to read the input. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of elibol Sent: January 18, 2006 1:25 PM To: Flashcoders mailing list Subject: Re: [Flashcoders] voice recognition in flash That's way intense Ralph, it sounds like what I've been waiting for my entire life!
