HI,

plz. help me find out the speaker recognition basic fundamentals steps, algorithm,flow-chart along with a report.

The main algorithms used for speaker recognition are k-Nearest neighbour, neural network and gaussian mixture models(GMM).
In this paper, we propose a new usable speech extraction method to improve the SID performance under the co-channel situation based on the pitch information obtained
from a robust multi-pitch tracking algorithm.

An abstract taken from Comparing speaker recognition techniques is available here:

This paper presents a novel algorithm for reducing the computational complexity of identifying a speaker within a Gaussian mixture speaker model (GMM) framework.
