This book focuses on use of voice as a biometric measure for
personal authentication. In particular, "Speaker Recognition"
covers two approaches in speaker authentication: speaker
verification (SV) and verbal information verification (VIV). The SV
approach attempts to verify a speaker's identity based on his/her
voice characteristics while the VIV approach validates a speaker's
identity through verification of the content of his/her
utterance(s). SV and VIV can be combined for new applications. This
is still a new research topic with significant potential
applications. The book provides with a broad overview of the recent
advances in speaker authentication while giving enough attention to
advanced and useful algorithms and techniques. It also provides a
step by step introduction to the current state of the speaker
authentication technology, from the fundamental concepts to
advanced algorithms. We will also present major design
methodologies and share our experience in developing real and
successful speaker authentication systems. Advanced and useful
topics and algorithms are selected with real design examples and
evaluation results. Special attention is given to the topics
related to improving overall system robustness and performances,
such as robust endpoint detection, fast discriminative training
theory and algorithms, detection-based decoding, sequential
authentication, etc. For example, the sequential authentication was
developed based on statistical sequential testing theory. By adding
enough subtests, a speaker authentication system can achieve any
accuracy requirement. The procedure of designing the sequential
authentication will be presented. For any presented technique, we
will provide experimental results to validate the usefulness. We
will also highlight the important developments in academia,
government, and industry, and outline a few open issues. As the
methodologies developed in speaker authentication span several
diverse fields, the tutorial book provides an introductory forum
for a broad spectrum of researchers and developers from different
areas to acquire the knowledge and skills to engage in the
interdisciplinary fields of user authentication, biometrics, speech
and speaker recognition, multimedia, and dynamic pattern
recognition.
