Double talk, Geigel

Started by July 6, 2005

I am implementing a EC for a university project, and I have some problems to detect double talk condition with the Geigel's algorithm. I am using this expression for detect the doble talk
|y(n)| >= k max [|x(n)|, |x(n-1)|, .., |x(n-L)|]
where :
y: near speech
x: far speech
The questions are:
I must use others conditions furthermore Geigel to detect the DT?
What is the value of the constant k?
K must be variable?

Best regards
