CHAPTER 1: Overview of Clinical Phonetics Flashcards
CLINICAL PHONETICS
Applications of phonetics to describe speech differences and disorders, including information about speech sounds and the perceptual skills used in clinical settings.
PHONETICS
The study of the perception and production of speech sounds.
TWO-WAY SCORING
A perceptual system in which speech sound productions are dichotomized into two classes representing typical versus atypical behavior (e.g., correct vs. incorrect, right vs. wrong, etc.).
FIVE-WAY SCORING
A perceptual system in which speech sounds are classified as typical versus one of four error types: an addition, a deletion (or omission), a subsitution, or a distortion.
DELETION (or OMISSION)
A speech production error in which a sound is omitted.
SUBSTITUTION
A speech production error in which a speech sound is replaced by another speech sound.
DISTORTION
A speech production error in which a speech sound is recognizable as the correct sound but is not produced exactly correctly.
ADDITION
A speech production error in which a sound is incorrectly added (before or after) to another sound.
PHONETIC TRANSCRIPTION
A visual representation of speech sounds, typically accomplished with the symbols of the International Phonetic Association (IPA). The main symbols represent individual phonemes or allophones, and transcriptions also may include marks for sound modifications, stress level, and other aspects of speech. Broad transcription pertains mainy to phonemes of a language, whereas narrow transcription includes finer variations including allophonic modifications.
BROAD TRANSCRIPTION
Phonetic transcription that uses phonemes exclusively and does not indicate finer variations such as those marked by diacritics in a narrow transcription.
NARROW (CLOSE) TRANSCRIPTION
Includes symbols to represent both the speech sounds produced and symbols that describe slight variations in the production of those sounds.
LINGUISTIC COMPLEXITY
The context in which a sound to be transcribed is embedded, which may range from a sound in isolation to a sound occurring in conversational speech.
RESPONSE COMPLEXITY
The number of target sounds to be transcribed, which may vary from only one sound to all sounds occurring in a section of speech.
TARGET SOUND
The sound to be transcribed, as it occurs in isolation or together with other speech sounds.
A clinician asks a child to say some words, each of which contains one r sound (e.g., rug, rabbit, car). After each word, the clinician records whether the child said the r sound correctly.
What is the linguistic complexity? System complexity? Response complexity?
Linguistic Complexity: word
System Complexity: two-way scoring
Response Complexity: single sound
