This book discusses the impact of spectral features extracted from frame
level, glottal closure regions, and pitch-synchronous analysis on the
performance of language identification systems. In addition to spectral
features, the authors explore prosodic features such as intonation,
rhythm, and stress features for discriminating the languages. They
present how the proposed spectral and prosodic features capture the
language specific information from two complementary aspects, showing
how the development of language identification (LID) system using the
combination of spectral and prosodic features will enhance the accuracy
of identification as well as improve the robustness of the system. This
book provides the methods to extract the spectral and prosodic features
at various levels, and also suggests the appropriate models for
developing robust LID systems according to specific spectral and
prosodic features. Finally, the book discuss about various combinations
of spectral and prosodic features, and the desired models to enhance the
performance of LID systems.
