You can figure out a way to record sound to a sound file (could be WAV, MP3, OGG, whatever).
Then when you save that file, convert it to byte, and compare it to the original byte.
Of course save the file in a temprorary location and then delete it.
Say if you want voice authentification.
hmm yea that's what im trying to do but im thinking if theres a way to convert a speech to text - there is a step somewhere inside that converts the speech to byte right? i want to do that... if its possible.. if not ill stick to voice recording - which seems to be another 24 hours of work for me! thanks alot for replying. really appreaciate it!
