Paralanguage

sigh

Paralanguage refers to non-verbal elements of spoken communication used to modify meaning and convey emotion, such as change in pitch, volume, or intonation. Paralanguage may be expressed consciously or unconsciously. The term ‘paralanguage’ should not be confused with ‘kinesics,’ or the study of body language. While kinesics is non-linguistic (it is not necessarily related to vocal or written language), paralanguage is. Paralinguistic information, because it is phenomenal, belongs to the external speech signal but not to the arbitrary conventional code of language.

The paralinguistic properties of speech play an important role in human speech communication. There are no utterances or speech signals that lack paralinguistic properties, since speech requires the presence of a voice that can be modulated. This voice must have some properties, and all the properties of a voice as such are paralinguistic. However, the distinction linguistic vs. paralinguistic applies not only to speech but to writing and sign language as well, and it is not bound to any sensory modality. Even vocal language has some paralinguistic as well as linguistic properties that can be seen (lip reading, McGurk effect), and even felt, e.g. by the Tadoma method (a touch based language for the deafblind).

Speech signals that arrive at a listener’s ears have acoustic properties that may allow listeners to localize the speaker (distance, direction). Sound localization functions in a similar way also for non-speech sounds. The perspectival aspects of lip reading are more obvious and have more drastic effects when head turning is involved. The speech organs of different speakers differ in size. As children grow up, their organs of speech become larger and there are differences between male and female adults. The differences concern not only size, but also proportions. They affect the pitch of the voice and to a substantial extent also the formant frequencies, which characterize the different speech sounds. The organic quality of speech has a communicative function in a restricted sense, since it is merely informative about the speaker. It will be expressed independently of the speaker’s intention. Paralinguistic cues such as loudness, rate, pitch, pitch contour, and to some extent formant frequencies of an utterance, contribute to the emotive or attitudinal quality of an utterance. Typically, attitudes are expressed intentionally and emotions without intention, but attempts to fake or to hide emotions are not unusual.

Consequently, paralinguistic cues relating to expression have a moderate effect of semantic marking. That is, a message may be made more or less coherent by adjusting its expressive presentation. For instance, an utterance such as ‘I drink a glass of wine every night before I go to sleep’ is coherent when made by a speaker identified as an adult, but registers a small semantic anomaly when made by a speaker identified as a child. This anomaly is significant enough to be measured through electroencephalography. Individuals with disorders along autism spectrum have a reduced sensitivity to this and similar effects. Emotional tone of voice, itself paralinguistic information, has been shown to affect the resolution of lexical ambiguity. Some words have homophonous partners; some of these homophones appear to have an implicit emotive quality, for instance the sad ‘die’ contrasted with the neutral ‘dye’; uttering the word in a sad tone of voice can result in a listener taking that word as significant. Ordinary phonetic transcriptions of utterances reflect only the linguistically informative quality. The problem of how listeners factor out the linguistically informative quality from speech signals is a topic of current research.

Some of the linguistic features of speech, in particular of its prosody (rhythm, stress, and intonation), are paralinguistic or pre-linguistic in origin. A most fundamental and widespread phenomenon of this kind is described by linguist John Ohala as the ‘frequency code’ (according to which high pitch symbolizes small and weak while low pitch symbolizes big and strong). This code works even in communication across species. It has its origin in the fact that the acoustic frequencies in the voice of small vocalizers are high while they are low in the voice of large vocalizers. This gives rise to secondary meanings such as ‘harmless,’ ‘submissive,’ ‘unassertive,’ which are naturally associated with smallness, while meanings such as ‘dangerous,’ ‘dominant,’ and ‘assertive,’ are associated with largeness. In most languages, the frequency code also serves the purpose of distinguishing questions from statements. It is universally reflected in expressive variation, and it is reasonable to assume that it has phylogenetically given rise to the sexual dimorphism that lies behind the large difference in pitch between average female and male adults.

In text-only communication such as email, chatrooms and instant messaging, paralinguistic elements can be displayed by emoticons, font and color choices, capitalization and the use of non-alphabetic or abstract characters. Nonetheless, paralanguage in written communication is limited in comparison with face-to-face conversation, sometimes leading to misunderstandings.

A gasp is a kind of paralinguistic respiration in the form of a sudden and sharp inhalation of air through the mouth. A gasp may indicate difficulty breathing, and a panicked effort to draw air into the lungs. Gasps also occur from an emotion of surprise, shock or disgust. Like a sigh, a yawn, or a moan, a gasp is often an automatic and unintentional act. Gasping is closely related to sighing, and the inhalation characterizing a gasp induced by shock or surprise may be released as a sigh if the event causing the initial emotional reaction is determined to be less shocking or surprising than the observer first believed. As a symptom of physiological problems, apneustic respirations are gasps related to the brain damage associated with a stroke or other trauma.

A sigh is a kind of paralinguistic respiration in the form of a deep and especially audible, single exhalation of air out of the mouth or nose, that humans use to communicate emotion. It is voiced pharyngeal fricative (a consonant produced by forcing air through a narrow channel), sometimes associated with a guttural glottal breath exuded in a low tone. It often arises from a negative emotion, such as dismay, dissatisfaction, boredom, or futility. A sigh can also arise from positive emotions such as relief, particularly in response to some negative situation ending or being avoided. Like a gasp, a yawn, or a moan, a sigh is often an automatic and unintentional act. In literature, a sigh is often used to signify that the person producing it is lovelorn. Scientific studies show that babies sigh after 50 to 100 breaths. This serves to improve the mechanical properties of lung tissue, and it also helps babies to develop a regular breathing rhythm. Behaviors equivalent to sighing have also been observed in animals such as dogs, monkeys, and horses. In text messages and internet chat rooms, or in comic books, a sigh is usually represented with the word itself, ‘sigh,’ (possibly within asterisks, *sigh*).
