This updated book expands upon prosody for recognition applications of speech processing. It includes importance of prosody for speech processing applications; builds on why prosody needs to be incorporated in speech processing applications; and presents methods for extraction and representation of prosody for applications such as speaker recognition, language recognition and speech recognition.

The Akathistos Hymn, the most famous work of Byzantine hymnography, has been enshrined in the Orthodox liturgy since the year 626, and its image of the Virgin Mary has exerted a strong influence upon Marian poetry and literature. Anonymous, undated and highly rhetorical, the hymn has presented a challenge to scholars over the years.
This study has been undertaken by an innovative method. The approach brings new insights to the era which brought forth the hymn, and the metaphorical image of the Virgin becomes conceptually accessible to the modern-day reader. The investigation leads to the conclusion that the Council of Ephesus (431) constitutes the most likely historical context for the hymn's composition.
The book will be of value to all scholars of early Byzantine and Marian studies.
