1Phonetics as a scientific study of speech Today we will speak about phonetics as a scientific /'saın'tıfık/ study of speech.We will have a general overview of issues which occur in phonetic studies.
2Outline (1) The objectives of phonetics Speech communication – encoding and decoding the messageAreas of phonetic studiesInformation conveyed in speechTypes of communication (vocal, non-vocal, verbal, non-verbal)
3Outline (2)The semiotic framework (Laver, Principles of Phonetics, 1994): linguistic code and signsPattern (form) and variability (substance)Phonetics vs. PhonologyCommunicative and informative behaviorLinguistic, paralinguistic and extralinguistic communication
4The objective of phonetics Investigation of speech communication by recording, describing and interpreting articulated utterances:speech communication (SC) – a codespoken utterances – signs of this coded systemSC – effective only between people skilled in the production and interpretation of the relevant signsSC has many layers which carry different types of informationUtterances - /’aterensys/Semiotic - /'semjo'tık/
5Speech communication (1) Manipulation of the speech signalPattern, linguistic formmessagelistener(receiver)speaker(sender)encodingThe speaker manipulates her speech signal in such a way as to produce an appropriate pattern or linguistic form which encodes the intended message.
6Speech communication (2) Decoding:Linguistic formPatternFeatures of the signalInformation:SemanticEvidentialRegulativelistener(receiver)messageThe message reaches the listener. The listener decodes the linguistic form of the message and receives information about the speaker (physical, psychological and social features).Semantic - the direct meaning of a spoken utteranceRegulative - /'regju'leıtIf/Regulative information identifies the speaker’s desire to retain or to yield the role of the speaker during the conversation
7Three areas of phonetic study Articulatory Phoneticsconstruction and function of the speech organs (larynx, vocal cords, tongue, lips, etc.)the use of the speech apparatus to produce the speech soundsAcoustic Phoneticsthe acoustic structure of speech - frequencies, intensities, spectra, etc.high-precision measuring and recording instrumentsAuditory Phoneticsconstruction and function of the hearing organsmechanisms by which the signs are perceived by the speaker using the auditory channelproceed - /pre'sid/Articulatory - /a:'tıkju'leıtrı/Auditory - /o:'dıtrı/
8Information conveyed in speech (1) Semantic informationdirect meaning of a spoken utterance (the propositional content of the communicative acts of conversation)the more complex the proposition the more likely it is going to be communicated by spoken words e.g. “come here” can be signaled solely by a hand movement (only visual channel)
9Information conveyed in speech (2) Evidential information - carried by signs which act as attributive markers on the basis of which the listeners attributes personal features to the speaker:Physical markers (e.g. sex, age, state of health) conveyed by voice qualitySocial markers (e.g. regional affiliation, educational and social status, occupation) signaled by accent, vocabulary, dialectPsychological markers (personality, affective state, mood) conveyed by the tone of voiceConvey - /kon'veı/
10Information conveyed in speech (3) Regulative informationspeaker’s desire to retain or to yield the role of the speaker during the conversationto control the time-sharing of the interactiontaking and giving turns in a conversationcontrolled by special mechanismsspecific to a given language communitysignaled by prosody (intonation, timing) and by non- vocal and non-verbal behavior (e.g. eye contact, head movement)The skill of taking and giving turns in a conversation is specific to a given language community and has to be learned when speaking a foreign language. (turn-taking and turn giving signaled by prosody and signals from the visual channel: eye contact, head movement)
11How do we communicate information? (1) Vocal behavioraudibleimparts semantic, evidential and regulative informationNon-vocal behaviorvisualimparts evidential and regulative informationuses gesture, posture, head and body movements, facial expression, gaze, eye contact (coded system of communication)except for the facial expression (a universal aspect), the other aspects of the non-vocal behavior are particular to the culture of the speaker.the non-vocal aspects lie outside the scope of the phonetic studiesImpart – przekazywać, nadawać
12How do we communicate information? (2) Verbally – using verbal elementsinclude vowels, consonants and word stressidentification of individual words as units of spoken languageverbal elements are linguisticNon-verbally – by means of non-verbal elementsserve function other than that of the verbal identificationinclude intonation and stress (for emphasis)non-verbal elements are linguistic or non-linguisticFacial expression, gesture, posture – non-vocal and non- verbalVerbally – by means of verbal elements which can be defined as aspects of communicative behavior that serve to identify individual words as units of spoken language. Verbal elements include vowels and consonants and word stress. VE are linguistic.Non-verbally – by means of non-verbal elements that serve function other than that of the verbal identification. Non-verbal elements include intonation and stress used for the purpose of emphasis.N-VE are linguistic and non-linguistic.Facial expression, gesture, posture – non-vocal and non-verbal
13Linguistic code and signs (1) we communicate using a linguistic code that consists of signs such as wordswords are arbitrary signsreferentculturally determined linktreesign
14Linguistic code and signs (2) Vowels and consonants are also arbitrary signsa many-to-one relationship:speech sounds/a/vowel
15Linguistic code and signs (3) Non-arbitrary signssignreferentdirect linkHigher pitch -> small vocal folds (female speaker or a child)Higher overall pitch -> small vocal folds (female speaker, child)Lower overall pitch -> large vocal folds (male speaker)
16The dual structure of the linguistic code Linguistic messages (utterances) are created at two levelsGrammatical – abstract grammatical elements such as words, phrases, clauses and sentencesmade up of combination of phonological units,represent the entities in the external semantic worldPhonological – abstract phonological elementsthey act as building blocks for the construction of the higher-level grammatical unitssegmental elements such as vowels and consonants (speech-sounds) and suprasegmental units such as syllables, rhythmic units and units of intonation and toneThe objective of phonetics is to describe the speech-sounds and to explore and explain their relationship with the phonological level of the linguistic structure.
17Pattern and variability variability is the feature of pronunciationthe perceiver is able to discern the distinctive patterns in speech sounds that identify the phonological unitsphonological and grammatical knowledge – reconstitution of the intended message from partial cluesWe already spoke about patterns – they are defined as representatives of linguistic units. Pattern is an abstract concept, like e.g. vowel /a/, it needs to be realized or manifested to exist in the real world.Variability /'verja'bıltı/ is an inherent characteristic of pronunciation both within and between speakers. However, despite the variability the perceiver is able to discern the distinctive patterns in speech sounds that identify the phonological units involved. Even in real, spontaneous speech which very often lacks full patterns the human perception is capable of reconstituting the intended message from partial clues -they rely on their phonological and grammatical knowledge.Reduced utterance: She sh---d --v- giv-n --im the package.Full utterance: She should have given him the package.
18Form and substance Form = pattern represents a linguistic unitneeds to be realized or manifested to exist in the real worldSubstance – realization of the patternGruszka – pear /pe(r)/substanceformJa lubię jabłka, a oni lubią gruszki.
19Phonetics and phonology both concern themselves with the form and the substance, but vary in their primary focusphonetics – substancerealization of formal symbolic patters and features conveying evidential and regulative informationphonology – form
20Communicative and informative behavior Information in speech can be conveyed by:Communicative signals – intended by the sender to make the receiver aware of something of which he was not previously aware.Informative signals – make the receiver aware of something of which he was not previously aware regardless of the intention of the sender.Informative signals – evidential information e.g. physical characteristics of the speaker
21Linguistic, paralinguistic and extralinguistic communication (1) the dual-level code of the spoken language (phonological and grammatical units)vocal, verbal, communicative and informativeParalinguistic communicationtone of voice, non-vocal behaviorinformation about the attitudinal, affective or emotional stateregulation of the time-sharing of the conversationvocal, non-vocal, verbal, non-verbal, communicative and informativeLinguistic behavior in the commonest form it consists in using the dual-level code of the spoken language made up of the phonological and grammatical units.Paralinguistic behavior includes communication by the tone of voice.Unlike in the linguistic communication in the PC non-vocal elements play a very large part.It has two objectives: to carry the information about the attitudinal, affective or emotional state and to regulate the time-sharing of the conversation.
22Linguistic, paralinguistic and extralinguistic communication (2) Paralinguistic communication:Similarity to the linguistic communication: the meaning of the coded paralinguistic communication is arbitrary e.g. falsetto in English (mocking, effeminacy) and Tzeltal (showing great respect)Difference from the linguistic communication: the sequential structure plays no role and sequential relationships are important only in the judgments about the relative degree of the manifestation of the feature e.g. estimating the change in the speaking rateSimilarity to the linguistic c. – paralinguistic signs form a coded type of communication whose meaning is arbitrary (and thus specific to a given community or culture) e.g. falsetto in English can be used to mock somebody or to express one’s accusation of effeminacy /ı'femınsı/ (when mimicking), but in a Mayan language Tzeltal it indicates a great respect when greeting somebody.Unlike the linguistic communication, the paralinguistic communication is not sequential (the paralinguistic signal can be used at any moment in the course of the utterance) and sequential relationships are important only in the judgments about the relative degree of the manifestation of the feature e.g. the listener can notice that the speaker started to speak at a slower pace only if he had a chance to assess the speaker’s earlier rate of articulation.
23Linguistic, paralinguistic and extralinguistic communication (3) features of the speech signal that are not involved in the realization of the linguistic or paralinguistic communicatione.g. voice quality - information about speaker’s state of health (smoker), age etc.non-coded, non-communicative and informativeevidential informationExtralinguistic communication is realized by the features of the speech signal that are not involved in the realization of the linguistic and paralinguistic communication.Tracheotomy - /'trækı‘otomı/This type of behavior is non-coded, non-communicative and informative and conveys evidential information.Most often social, psychological and physical characteristics are related to the linguistic, paralinguistic and extralinguistic information. However, there is no direct correspondence between types of information conveyed in speech and the three types of communication. For example a loud resonant voice (paralinguistic feature) can be associated with an authoritative personality (psychological marker), but it can be the outcome of a large and powerful physique (physical marker).
