Prosody (linguistics)
Study of speech elements beyond individual vowels and consonants.
Prosody in linguistics is the study of elements of speech—such as intonation, stress, rhythm, and loudness—that occur simultaneously with individual phonetic segments like vowels and consonants. Often referred to as suprasegmentals when they extend across more than one phonetic segment, prosody reflects the nuanced emotional features of the speaker or their utterances, including emotional state, utterance form (statement, question, or command), irony, sarcasm, emphasis, contrast, and focus, displaying elements of language not encoded by grammar, punctuation, or vocabulary.

Lore & Background
Prosody is studied through both auditory measures (subjective impressions of the listener) and objective measures (physical properties of sound waves and articulation). These measures do not correspond linearly, and most studies have relied on auditory analysis using auditory scales. Major auditory variables include pitch, length, loudness, and timbre, which correspond acoustically to fundamental frequency, duration, intensity, and spectral characteristics. Different combinations of these variables are exploited in intonation, stress, rhythm, and tempo.
Reader's Guide
Prosody is a natural component found across all languages, though the defining features that display nuanced emotions differ across languages and cultures. It serves perceptually significant functions in English and other languages, contributing to speech recognition and comprehension. Prosody assists listeners in parsing continuous speech and recognizing words by providing cues to syntactic structure, grammatical boundaries, and sentence type. Boundaries between intonation units are often associated with grammatical or syntactic boundaries, marked by pauses, slowing of tempo, and pitch reset. The study of prosody distinguishes between personal voice characteristics (not linguistically significant) and independently variable prosodic features used contrastively to communicate meaning.
Did You Know?
- Prosody reflects elements of language not encoded by grammar, punctuation, or choice of vocabulary.
- Auditory and objective measures of prosody do not correspond in a linear way.
- English intonation is often said to be based on division of speech into units, highlighting particular words and syllables, and choice of pitch movement.
- Stress functions as the means of making a syllable prominent, with pitch being the most efficacious cue and loudness the least so.
