I am trying to understand how the algorithm from "An Improved Endpoint Detector for Isolated Word Recognition" from Rabiner, 1981 works but I cannot understand it.

The paper begins with the energy calculation from the previous paper by Rabiner, in 1975 (which, I posted here that I cannot find it) and then goes on to describe the algorithm with the thresholds.

The flowcharts are completely not understandable from me, I think these are the most weird diagrams I have ever see (I am not in the digital signal processing field).

Can anyone point to a program in C or matlab that implement this algorithm?

Thanks a lot,
Bill.
