Title: Voice Matching Software for Security Solution
Post by: TechnoMania on 2004-09-25 13:04:25
Hi All,

I dunno is such a kind of a software exists or is possible thru programming.

Code: [Select]
All i want is  
~~~~~~~
The is a voice file present on a Computer which was recorded earlier by the person (suppose he has recorded his voice as "hi i am xyz").

Now i have to verify that the voice is his only so he will talk the same thing which
was recorded earlier i.e. "hi i am xyz" if the 2 voice match the software will
tell me that the 2 voice match exactly.

the frequecy peaks will be matched to check the voice i suppose or something like that.


Is there such a type of software in existance or it exists only in movies.

If yes whats the name of the software and what all things will be required to
configure the software on my pc.

If such a thing does not exist just leave it i just wanted to know about it.

"automatic speaker recognition" is also a good search term.

Software exists, sure, but it is not very reliable. It's still an active research area.

Yes, it's an definitely an interesting area of research to study. Most speech recognition systems are based upon Hidden Markov Models which are statistical models. ASR is a form of dictation.  . Look up "grammar constrained recogniton" and "natural language recognition". What I can gather from reading a little those are the two most common types, each one has there obvious advantages and disadvantages.

Random examples: [a href="http://www.dragonsys.com/speechworks/speechsecure/]SpeechSecure[/url] (commercial) or PUMS (http://cs.joensuu.fi/pages/pums/results.html) (research). I'm sure you'll find others through google.
