Though there has been considerable research on Spanish phonetics and phonology, until now, there has been no in-depth and complete descriptive reference work. Fonética y fonología descriptivas de la lengua española, volumes 1 and 2, is a comprehensive reference, written in Spanish, describing the phonetics and phonology of Spanish. Edited by Juana Gil and Joaquim Llisterri, and including contributions from an international group of scholars, these books provide a comprehensive overview for understanding topics across Spanish phonetics and phonology, making clear what further research is needed. Together, these two volumes offer a survey of Spanish descriptive phonetics and phonology. Volume 1 focuses on the segmental-consonant and vowel sound-properties of phonetic units and phonic phenomena. Each topic is examined from three angles: its phonetic description, its phonological analysis, and the characterization of its variation. The phonetic description is given from the perspectives of production, acoustic analysis, and perception. The phonological analysis includes the different treatments to which a certain phenomenon has been subjected and considers the different theoretical perspectives that have been used to address it. With state-of-the-art information on all topic related to the sounds of Spanish, Foné y fonología descriptivas de la lengua española will be a valuable resource for researchers, students, and scholars of Spanish linguistics who wish to deepen their understanding of the phonetic and phonological characteristics of all the varieties of the Spanish language.
