LECTURE #9 - pediatric speech sound disorders Flashcards
how are consonant/vowel sounds classified ?
Consonant and vowel sounds are classified based on how and where they’re made in the mouth and throat:
Consonants: Classified by the amount of airflow restriction (like blocking with the lips or tongue) and whether the vocal cords vibrate (voiced or voiceless).
Vowels: Classified by the shape and position of the mouth and tongue, with an open vocal tract and always using vocal cord vibration.
what are the different types of speech sound disorders ?
- Articulation Disorders
- Phonological Disorders
- Motor Speech Disorders
- Resonance Disorders
speech sounds; what is a phoneme ?
the smallest unit of sound in a language that conveys meaning
what is an example of different phonemes ?
e.g., /p/ and /b/ (e.g., pat versus bat)
how many letters in the english alphabet ?
26
what is a problem with the alphabet ?
there is no simple symbol to sound relationship
what are examples of simple symbol-to-sound relationships
- the ‘s’ sound = soup, bass, base, face vs hose
- the ‘er’ sound = jerk, fir, fur, word, butter, earth
- the ‘sh’ sound = ship, station, chef, moustache
what does IPA stand for ?
international phonetic alphabet
what is the IPA?
unambiguous system for representing sounds of speech
how IPA symbols are there ?
42
how many of the 42 IPA symbols are vowels and consonants ?
18 vowels and 24 consonants
what is an example of a IPA speech sound ?
‘“sh”
- SH ip
- sta TI on
- CH ef
- mousta CHE
how fo we classify consonants ?
by using the 3 dimensions aling which sounds are classified
what are the 3 dimensions along which sounds are classified ?
- place
- manner
- voicing
define “place” as one of the 3 dimensions :
where in vocal tract the constriction occurs as the sounds is produced (e.g., /p/ = bilabial)
define “manner” as one of the 3 dimensions :
how air is modified as it travels through vocal tract (e.g., /p, b, t, d, k, g/ = stops)
define “voicing” as one of the 3 dimensions :
whether vocal folds are vibrating while sound is produces (e.g., /z/ = voiced, /s/ = voiceless)
explain what voice vs voiceless means in the sense of consonant classification :
In consonant classification, “voice” and “voiceless” refer to whether or not your vocal cords vibrate when making a sound
define “voiced consonants” :
are sounds you make with vocal cord vibration. If you put your fingers on your throat, you’ll feel a slight vibration when you say sounds like b, d, or g
define “voiceless consonants” :
are sounds you make without vocal cord vibration. When you make these sounds, like p, t, or k, you won’t feel that same vibration in your throat
between voiced and voiceless which is no vibration vs vibration ?
- Voiced = vocal cords vibrating
- Voiceless = no vocal cord vibration
what are the places of articulation ?
- bilabial (m,b,p)
- labio-dental (f,v)
- lingua-dental (th)
- lingua-alveolar (t,s)
- lingua-palatal (sh)
- glottal (h)
what part of the body are the following from ?
- bilabial (m,b,p)
- labio-dental (f,v)
- lingua-dental (th)
- lingua-alveolar (t,s)
- lingua-palatal (sh)
- glottal (h)
bilabial = formed by bringing both lips together
labio-dental = formed by touching the bottom lip to the upper front teeth
lingua-dental = formed by placing the tongue against the upper front teeth
lingua-alveolar = formed by placing the tongue close to the alveolar ridge (the ridge just behind the upper front teeth)
lingua-palatal = formed by raising the tongue toward the hard palate (the roof of the mouth just behind the alveolar ridge)
glottal = formed in the glottis (the space between the vocal cords in the throat
how many palces of articulation are there ?
6
what does “vocing” mean ?
Voicing is the process of making a sound by vibrating your vocal cords.
When you produce a voiced sound, like z in “zebra,” your vocal cords are close together and vibrate as air passes through. In contrast, for a voiceless sound like s in “snake,” your vocal cords stay apart, so they don’t vibrate as air flows through.
what are voiced sounds ?
vocal cords vibrate (like b, d, g, z)
what are voiceless sounds ?
no vocal cord vibration (like p, t, k, s)
what are “cognates” ?
speech sounds that share same manner and palce of articulation, but differ along voicing dimension
what are some examples of cognates ?
/d/ & /t/ , /f/ & /v/
TRUE OR FALSE
no two consonants fit in the same spot
TRUE
what are consonants ?
Consonants are sounds in speech made by blocking or restricting airflow in some way with parts of the mouth
TRUE OR FALSE
consonants are different from vowels
TRUE
how are consonants and vowels different ?
They’re different from vowels, which are produced with a more open vocal tract and let air flow freely.
what are vowels
are speech sounds produced by letting air flow freely through the mouth without any significant blockage from the tongue, lips, or teeth.
what are the vowels ?
A, E, I, O, and U (sometimes Y)
how many vowels are there ?
5 main vowels
