This volume should be of great interest to phoneticians, phonologists, and both historical and cognitive linguists. Using data from the Romance languages for the most part, the book explores the phonetic motivation of several sound changes, e.g., glide insertions and elisions, vowel and consonant insertions, elisions, assimilations and dissimilations. Within the framework of the DAC (degree of articulatory constraint) model of coarticulation, it clearly demonstrates that the typology and direction of these sound changes may very largely be accounted for by the coarticulatory effects occurring between adjacent or neighbouring phonetic segments, and by the degrees of articulatory constraint imposed by speakers on the production of vowels and consonants. The phonetically-based explanations presented here are formulated on the basis of coarticulation data from speech production and perception research carried out during the last fifty years and are complemented with data on the co-occurrence of phonetic segments in lexical forms of the languages being considered. Attention is also paid to the role that positional and prosodic factors play in sound change implementation, as well as to the cognitive and peripheral strategies involved in segmental replacements, elisions and insertions.

Examines advanced approaches to sound change from various theoretical and methodological perspectives, including articulatory variation and modeling, speech perception mechanisms and neurobiological processes, geographical and social variation, and diachronic phonology.

The World's Major Languages features over 50 of the world's languages and language families. This revised edition includes updated bibliographies for each chapter and up-to-date census figures. The featured languages have been chosen based on the number of speakers, their role as official languages and their cultural and historical importance. Each language is looked at in depth, and the chapters provide information on both grammatical features and on salient features of the language's history and cultural role. The World’s Major Languages is an accessible and essential reference work for linguists.

This volume presents a collection of research studies on sophisticated and functional computational instruments able to recognize, process, and store relevant situated interactional signals, as well as, interact with people, displaying reactions (under conditions of limited time) that show abilities of appropriately sensing and understanding environmental changes, producing suitable, autonomous, and adaptable responses to various social situations. These social robotic autonomous systems will improve the quality of life of their end-users while assisting them on several needs, ranging from educational settings, health care assistance, communicative disorders, and any disorder impairing either their physical, cognitive, or social functional activities. The multidisciplinary themes presented in the volume will be interesting for experts and students coming from different research fields and with different knowledge and backgrounds. The research reported is particularly relevant for academic centers, and Research & Development Institutions.

The book investigates historical patterns of vowel diphthongization, assimilation and dissimilation induced by consonants – mostly (alveolo)palatals – in Romance. Compiling data from dialectal descriptions, old documentary sources and experimental phonetic studies, it explains why certain vowels undergo raising assimilation before (alveolo)palatal consonants more than others. It also suggests that in French, Francoprovençal, Occitan, Rhaetoromance and dialects from northern Italy, mid low vowel diphthongization before (alveolo)palatal consonants started out with the formation of non-canonical falling diphthongs through off-glide insertion, from which rising diphthongs could emerge at a later date (e.g., Upper Engadinian OCTO ‘eight’ > [ɔc] > [ɔ(ə̯)c] > [wac]). Both diphthongal types, rather than canonical falling diphthongs with a palatal off-glide, could also give rise to high vowels (dialectal French [li]

This book presents a formal, constraint-based account of the main diachronic and synchronic patterns of variation in the palatal sounds of the Romance languages. It will appeal to graduate students and researchers in historical linguistics, phonetics and phonology, Romance linguistics, and dialectology more broadly.

This comprehensive collection equips readers with a state-of-the-art description of clinical phonetics and a practical guide on how to employ phonetic techniques in disordered speech analysis. Divided into four sections, the manual covers the foundations of phonetics, sociophonetic variation and its clinical application, clinical phonetic transcription, and instrumental approaches to the description of disordered speech. The book offers in-depth analysis of the instrumentation used in articulatory, auditory, perceptual, and acoustic phonetics and provides clear instruction on how to use the equipment for each technique as well as a critical discussion of how these techniques have been used in studies of speech disorders. With fascinating topics such as multilingual sources of phonetic variation, principles of phonetic transcription, speech recognition and synthesis, and statistical analysis of phonetic data, this is the essential companion for students and professionals of phonetics, phonology, language acquisition, clinical linguistics, and communication sciences and disorders.

The syllable is a natural unit of organization in spoken language whose strongest cross-linguistic patterns are often explained in terms of a universal preference for the CV structure. Syllable patterns involving long sequences of consonants are both typologically rare and theoretically marginalized, with few approaches treating these as natural or unproblematic structures. This book is an investigation of the properties of languages with highly complex syllable patterns. The two aims are (i) to establish whether these languages share other linguistic features in common such that they constitute a distinct linguistic type, and (ii) to identify possible diachronic paths and natural mechanisms by which these patterns come about in the history of a language. These issues are investigated in a diversified sample of 100 languages, 25 of which have highly complex syllable patterns. Languages with highly complex syllable structure are characterized by a number of phonetic, phonological, and morphological features which serve to set them apart from languages with simpler syllable patterns. These include specific segmental and suprasegmental properties, a higher prevalence of vowel reduction processes with extreme outcomes, and higher average morpheme/word ratios. The results suggest that highly complex syllable structure is a linguistic type distinct from but sharing some characteristics with other proposed holistic phonological types, including stress-timed and consonantal languages. The results point to word stress and specific patterns of gestural organization as playing important roles in the diachronic development of these patterns out of simpler syllable structures.
