Lab session 2 :
Introduction to Hidden Markov Models
Course : Speech processing and speech recognition
Teacher : Prof. Herve Bourlard bourlard@idiap.ch
Assistants : Sacha Krstulovic sacha@idiap.ch
Mathew Magimai-Doss mathew@idiap.chGuidelines
The following lab manual is structured as follows :
each section corresponds to a theme
each subsection corresponds to a separate experiment.
The subsections begin with useful formulas and denitions that will be put in practice during the experiments.
These are followed by the description of the experiment and by an example of how to realize it
in Matlab.
If you follow the examples literally, you will be able to progress into the lab session without worrying
about the experimental implementation details. If you have ideas for better Matlab implementations,
you are welcome to put them in practice provided you don’t loose too much time : remember that a lab
session is no more than 3 hours long.
The subsections also contain questions that you should think about. Corresponding answers are given
right after, in case of problem. You can read them right after the question, but : the purpose of this lab
is to make you
Think !
If you get lost with some of the questions or some of the explanations, DO ASK the assistants or
the teacher for help : they are here to make the course understood. There is no such…
