Prosodic Analysis
In linguistics, prosody () is concerned with elements of speech that are not individual phonetic segments (vowels and consonants) 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. Prosody may reflect features of the speaker or the utterance: their emotional state; the form of utterance (statement, question, or command); the presence of irony or sarcasm; emphasis, contrast, and focus. It may reflect elements of language not encoded by grammar or choice of vocabulary. Attributes of prosody In the study of prosodic aspects of speech, it is usual to distinguish between auditory measures ( subjective impressions produced in the mind of the listener) and objective measures (physical properties of the sound wave and physiological characteristics of articulation that may be measured objectively). Auditory (subjective) and objective ( acoustic and articulatory) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linguistics
Linguistics is the scientific study of human language. It is called a scientific study because it entails a comprehensive, systematic, objective, and precise analysis of all aspects of language, particularly its nature and structure. Linguistics is concerned with both the cognitive and social aspects of language. It is considered a scientific field as well as an academic discipline; it has been classified as a social science, natural science, cognitive science,Thagard, PaulCognitive Science, The Stanford Encyclopedia of Philosophy (Fall 2008 Edition), Edward N. Zalta (ed.). or part of the humanities. Traditional areas of linguistic analysis correspond to phenomena found in human linguistic systems, such as syntax (rules governing the structure of sentences); semantics (meaning); morphology (structure of words); phonetics (speech sounds and equivalent gestures in sign languages); phonology (the abstract sound system of a particular language); and pragmatics (how social con ...

Pitch (music)
Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies. Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre. Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system. Perception Pitch and frequency Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conversation Analysis
Conversation analysis (CA) is an approach to the study of social interaction, embracing both verbal and non-verbal conduct, in situations of everyday life. CA originated as a sociological method, but has since spread to other fields. CA began with a focus on casual conversation, but its methods were subsequently adapted to embrace more task- and institution-centered interactions, such as those occurring in doctors' offices, courts, law enforcement, helplines, educational settings, and the mass media, and focus on nonverbal activity in interaction, including gaze, body movement and gesture. As a consequence, the term ''conversation analysis'' has become something of a misnomer, but it has continued as a term for a distinctive and successful approach to the analysis of interactions. CA and ethnomethodology are sometimes considered one field and referred to as ''EMCA''. History Conversation analysis was developed in the late 1960s and early 1970s principally by the sociologist Harv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juncture
Juncture, in linguistics, is the manner of moving (transition) between two successive syllables in speech. An important type of juncture is the suprasegmental phonemic cue by means of which a listener can distinguish between two otherwise identical sequences of sounds that have different meanings. Typology There are several kinds of juncture, the most widely used typology of which is: ;plus juncture:Also known as open juncture, this is subdivided into internal open juncture and external open juncture. It is the juncture that occurs at word boundaries. In phonetic transcription open juncture is transcribed , hence the name ''plus'' juncture. ;close juncture:Also known as a normal transition, this is a transition between segments (sounds) within a word. ;terminal juncture:Also known as falling, clause terminal or terminal contour, this is the juncture at the end of a clause or utterance with falling pitch before a silence. Other less common typologies exist, such as the divis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voice (phonetics)
Voice or voicing is a term used in phonetics and phonology to characterize speech sounds (usually consonants). Speech sounds can be described as either voiceless (otherwise known as ''unvoiced'') or voiced. The term, however, is used to refer to two separate concepts: *Voicing can refer to the ''articulatory process'' in which the vocal folds vibrate, its primary use in phonetics to describe phones, which are particular speech sounds. *It can also refer to a classification of speech sounds that tend to be associated with vocal cord vibration but may not actually be voiced at the articulatory level. That is the term's primary use in phonology: to describe phonemes; while in phonetics its primary use is to describe phones. For example, voicing accounts for the difference between the pair of sounds associated with the English letters "s" and "z". The two sounds are transcribed as and to distinguish them from the English letters, which have several possible pronunciations, depe ...

Mora (linguistics)
A mora (plural ''morae'' or ''moras''; often symbolized μ) is a basic timing unit in the phonology of some spoken languages, equal to or shorter than a syllable. For example, a short syllable such as ''ba'' consists of one mora (''monomoraic''), while a long syllable such as ''baa'' consists of two (''bimoraic''); extra-long syllables with three moras (''trimoraic'') are relatively rare. Such metrics are also referred to as syllable weight. The term comes from the Latin word for "linger, delay", which was also used to translate the Greek word χρόνος : ''chrónos'' (time) in its metrical sense. Formation The general principles for assigning moras to segments are as follows (see Hayes 1989 and Hyman 1985 for detailed discussion): # A syllable onset (the first consonant or consonants of the syllable) does not represent any mora. # The syllable nucleus represents one mora in the case of a short vowel, and two morae in the case of a long vowel or diphthong. Consonants se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isochrony
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. Three alternative ways in which a language can divide time are postulated: # The duration of every syllable is equal (syllable-timed); # The duration of every mora is equal (mora-timed). # The interval between two stressed syllables is equal (stress-timed). The idea was first expressed thus by Kenneth L. Pike in 1945, though the concept of language naturally occurring in chronologically and rhythmically equal measures is found at least as early as 1775 (in ''Prosodia Rationalis''). This has implications for linguistic typology: D. Abercrombie claimed "As far as is known, every language in the world is spoken with one kind of rhythm or with the other ... French, Telugu and Yoruba ... are syllable-timed languages, ... English, Russian and Arabic ... are stress-timed languages." While many linguists find the i ...

Prosodic Stress
In linguistics, and particularly phonology, stress or accent is the relative emphasis or prominence given to a certain syllable in a word or to a certain word in a phrase or sentence. That emphasis is typically caused by such properties as increased loudness and vowel length, full articulation of the vowel, and changes in tone. The terms ''stress'' and ''accent'' are often used synonymously in that context but are sometimes distinguished. For example, when emphasis is produced through pitch alone, it is called ''pitch accent'', and when produced through length alone, it is called ''quantitative accent''. When caused by a combination of various intensified properties, it is called ''stress accent'' or ''dynamic accent''; English uses what is called ''variable stress accent''. Since stress can be realised through a wide range of phonetic properties, such as loudness, vowel length, and pitch (which are also used for other linguistic functions), it is difficult to define stress ...

Power Spectrum
The power spectrum S_(f) of a time series x(t) describes the distribution of Power (physics), power into frequency components composing that signal. According to Fourier analysis, any physical signal can be decomposed into a number of discrete frequencies, or a spectrum of frequencies over a continuous range. The statistical average of a certain signal or sort of signal (including Noise (electronics), noise) as analyzed in terms of its frequency content, is called its spectrum. When the energy of the signal is concentrated around a finite time interval, especially if its total energy is finite, one may compute the energy spectral density. More commonly used is the power spectral density (or simply power spectrum), which applies to signals existing over ''all'' time, or over a time period large enough (especially in relation to the duration of a measurement) that it could as well have been over an infinite time interval. The power spectral density (PSD) then refers to the spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fundamental Frequency
The fundamental frequency, often referred to simply as the ''fundamental'', is defined as the lowest frequency of a periodic waveform. In music, the fundamental is the musical pitch of a note that is perceived as the lowest partial present. In terms of a superposition of sinusoids, the fundamental frequency is the lowest frequency sinusoidal in the sum of harmonically related frequencies, or the frequency of the difference between adjacent frequencies. In some contexts, the fundamental is usually abbreviated as 0, indicating the lowest frequency counting from zero. In other contexts, it is more common to abbreviate it as 1, the first harmonic. (The second harmonic is then 2 = 2⋅1, etc. In this context, the zeroth harmonic would be 0 Hz.) According to Benward's and Saker's ''Music: In Theory and Practice'': Explanation All sinusoidal and many non-sinusoidal waveforms repeat exactly over time – they are periodic. The period of a waveform is the smallest value of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
