For more info : Seminar on Speaker verification and GMM
This seminar is about Speaker verification, which tells whether the speaker’s voice is same as the registered voice, and GMM (Gaussian Mixture Model) which is one of the theories used in speaker modeling.
Basically, Speech recognition includes processes of Background modeling, Feature Extraction and Speaker modeling, which check on whether the input voice is same as the existing one.
In each stage, it proceeds the modeling with the characteristics, such as frequency, extracted from the vocal data. There are two ways to do this:
1. Generative Model – measures the similarity between the samples from each model.
2. Discriminative Model – discriminates each model with their characteristics and defines in which part they each belong to.
and GMM (Gaussian Mixture Model) is one of the Generative Model.
