In linguistics, creaky voice refers to a low, scratchy sound that occupies the vocal range below the common vocal register. It is a special kind of phonation in which the arytenoid cartilages in the larynx are drawn together; as a result, the vocal folds are compressed rather tightly, becoming relatively slack and compact. They normally vibrate irregularly at 20–50 pulses per second, about two octaves below the frequency of modal voicing, and the airflow through the glottis is very slow. Although creaky voice may occur with very low pitch, as at the end of a long intonation unit, it can also occur with a higher pitch. All contribute to make a speaker's voice sound creaky or raspy.
Phonology is the branch of linguistics that studies how languages or dialects systematically organize their sounds or, for sign languages, their constituent parts of signs. The term can also refer specifically to the sound or sign system of a particular language variety. At one time, the study of phonology related only to the study of the systems of phonemes in spoken languages, but may now relate to any linguistic analysis either:
Foreign accent syndrome is a medical condition in which patients develop speech patterns that are perceived as a foreign accent that is different from their native accent, without having acquired it in the perceived accent's place of origin.
Isochrony is the postulated rhythmic division of time into equal portions by a language. Rhythm is an aspect of prosody, others being intonation, stress, and tempo of speech.
In linguistics, prosody is concerned with elements of speech that are not individual phonetic segments but are properties of syllables and larger units of speech, including linguistic functions such as intonation, stress, and rhythm. Such elements are known as suprasegmentals.
Linking R and intrusive R are sandhi or linking phenomena involving the appearance of the rhotic consonant between two consecutive morphemes where it would not normally be pronounced. These phenomena occur in many non-rhotic varieties of English, such as those in most of England and Wales, parts of the United States, and all of the Anglophone societies of the southern hemisphere, with the exception of South Africa. These phenomena first appeared in English sometime after the year 1700.
Auditory phonetics is the branch of phonetics concerned with the hearing of speech sounds and with speech perception. It thus entails the study of the relationships between speech stimuli and a listener's responses to such stimuli as mediated by mechanisms of the peripheral and central auditory systems, including certain areas of the brain. It is said to compose one of the three main branches of phonetics along with acoustic and articulatory phonetics, though with overlapping methods and questions.
In linguistics, a segment is "any discrete unit that can be identified, either physically or auditorily, in the stream of speech". The term is most used in phonetics and phonology to refer to the smallest elements in a language, and this usage can be synonymous with the term phone.
In linguistics, intonation is variation in pitch used to indicate the speaker's attitudes and emotions, to highlight or focus an expression, to signal the illocutionary act performed by a sentence, or to regulate the flow of discourse. For example, the English question "Does Maria speak Spanish or French?" is interpreted as a yes-or-no question when it is uttered with a single rising intonation contour, but is interpreted as an alternative question when uttered with a rising contour on "Spanish" and a falling contour on "French". Although intonation is primarily a matter of pitch variation, its effects almost always work hand-in-hand with other prosodic features. Intonation is distinct from tone, the phenomenon where pitch is used to distinguish words or to mark grammatical features.
The phonology of second languages is different from the phonology of first languages in various ways. The differences are considered to come from general characteristics of second languages, such as slower speech rate, lower proficiency than native speakers, and from the interaction between non-native speakers' first and second languages.
ToBI is a set of conventions for transcribing and annotating the prosody of speech. The term "ToBI" is sometimes used to refer to the conventions used for describing American English specifically, which was the first ToBI system, developed by Mary Beckman and Janet Pierrehumbert, among others. Other ToBI systems have been defined for a number of languages; for example, J-ToBI refers to the ToBI conventions for Tokyo Japanese, and an adaptation of ToBI to describe Dutch intonation was developed by Carlos Gussenhoven, and called ToDI. Another variation of ToBI, called IViE, was established in 1998 to enable comparison between several dialects of British English.
Jennifer Sandra Cole is a professor of linguistics and Director of the Prosody and Speech Dynamics Lab at Northwestern University. Her research uses experimental and computational methods to study the sound structure of language. She was the founding General Editor of Laboratory Phonology (2009–2015) and a founding member of the Association for Laboratory Phonology.
Julia Hirschberg is an American computer scientist noted for her research on computational linguistics and natural language processing.
Lilias Eveline Armstrong was an English phonetician. She worked at University College London, where she attained the rank of reader. Armstrong is most known for her work on English intonation as well as the phonetics and tone of Somali and Kikuyu. Her book on English intonation, written with Ida C. Ward, was in print for 50 years. Armstrong also provided some of the first detailed descriptions of tone in Somali and Kikuyu.
