intro test 2 part 2 Flashcards
- International Phonetic Alphabet
- A set of phonetic symbols that could represent most of the sounds adequately.
- Each symbol represents only one sound
- Allophone
• Variants of phonemes
- Phonemic.
• Refers to abstract system of sounds
- What is phonetic
• Concrete productions of specific sounds.
- How many phonemes are there in English
• 46
- What phonemes should be developed by 3 ½
• P,M,H,W,B
- By 4 ½?
• N, NG, J, B, K, G, D, T
- By 5 ½?
• F
- By 6 ½?
• L, v, ʒ, ʃ, ð
- By 7 ½?
• S, r, z, θ
- Which phonemes where not reported?
• tʃ, dʒ
- What is language?
• An abstract system of symbols used to communicate
- What is speech?
• The production of speech sounds or actual production of oral language.
- What are the three consonant classification?
- Place of Articulation - describes the location of constriction
- Manner of Articulation – describes the degree type of constriction
- Voicing of Articulation – describes the presence or absence of vocal fold vibrations in the production of consonants.
- What is voicing?
- Speech sounds based on the behavior of the vocal folds
- Voiced: vocal folds are adducted (Closed)
- Voiceless: vocal folds are abducted (open)
- What is place?
- Bilabials- both lips (p, w)
- Labiodentals- Upper teeth/ lower lip (fricative)
- Lingua-dental- tongue/teeth
- Lingui-alveolar- tongue/alveolar ridge
- Langue- palatals – tongue/ hard palate
- Lingua-velars- tongue to soft palate (velum)
- Glottals- keep vocal folds open and let air pass through glottis
- Manner
- Plosive: produced by impounding air behind an occlusion in the vocal tract and releasing it suddenly (ex: /b/, /k/, /m/, /w/)
- Fricative: produced by forcing air through a narrow opening for a prolonged length of time (ex: /z/, /f/, /s/, /v/, th, sh, j, and /h/)
- Affricate: produced by narrowing an opening for the air to pass through, but in a short burst (ex: /tʃ/, /dʒ/)
- Nasal: produced by opening the velopharyngeal port to allow some air to resonate in the nasal cavity (ex: /m/, /n/, ng)
- Liquid: produced by air passing along one or both sides of the tongue (ex: /l/, /r/)
- Glide: produced by narrowing an opening for the air to pass through that are described as semi-vowels (ex: /w/, /j/)
- What is speech intelligibility?
- The degree in which people understand the sounds in words that a speaker produces.
- Judges as good, fair, poor or mild, moderate severe
- Measured By number of understandable words/ total number of word * 100
- What is prosody?
• The melody, flow and rhythm of spoken communication including melodic changes in syllable stress, pitch, loudness, and duration.
- What is the difference between articulation and phonology?
• Articulation=motor component
• Phonology = language component (patterns)
- Child has difficulty organizing their speech sounds into system of sounds contrast
- What is articulation disorder?
- Difficulty producing sounds as sounds sequences of language (problems with producing speech sounds)
- Reason may be unknown(children with functional speech disorders who do not have serious problems
- Reason may be known ( children with dysarthria who do have serious problems with muscle functions)
- What is articulation disorder attributed to?
• Fault placement, timing directions, pressure, speech or integrations of movement for lips, tongue, velum or mandible
- What are the types of articulation error?
- Omission
- Distortion
- Addition
- Substitution
- What is omission?
• Absence of a required sound in a word position or sound is left out of word
- What is distortion?
• Imprecise sounds production that does not match its normal production or sound produced is recognizable but inaccurate.
- What is addition?
• Sound that does not belong in a word is added
- What is substitution?
• Production of a wrong sound in place of a right one. Or incorrect sound is produced for target sound
- What is the place-manner-voice approach?
• Used to identify patterns of error
- What is final consonant deletion?
• Final consonants are omitted. Ex.”Bo for Boat” or Bee for Beep
what initial consonant deletion?
• Initial consonant are omitted. Ex. Ot for pot, us for bus. Eep for peep
- Cluster reduction
• one or come consonant of a cluster are omitted. Ex. Kate for skate, bu for blue, tong for strong
- Fronting
• Sounds produced in the front of the mouth are substituted for those produced at the back of the mouth. Tak for chalk, seep for sheep, tum for come
- Denasalization
• An oral sound is substituted for a nasal sound. Ex. Mad for man, brother for mother
- Reduplication or doubling
• A syllable of a target word is repeated. Baba for bottle, dada for dog, tata for television
- Unstressed syllable deletion
• The child says medo for tomato, tepone for telephone, ephent for elephant
- Epenthesis
• An unstressed vowel, typically the schwa, is inserted inappropriately ex. sapoon for spoon
- Phonological process
• Man ways (or PATTERNS) of simplifying difficult sounds production
- Consonant deletion process
• A child who omit s several final or initial consonants.
- What is diadochokinetic rate?
• Speed at which a speaker can repeat selected syllables.
