Introduction to Phonetics/Phonology

These flashcards cover key concepts from the Introduction to Phonetics/Phonology lecture.

What is phonetics?

The study of speech sounds used by all human languages to represent meanings.

What is phonology?

The study of the sound patterns of a particular language.

What are the three main branches of phonetics?

Articulatory phonetics, acoustic phonetics, auditory phonetics.

What does the Speech Chain Model describe?

The process of conveying a message from speaker to hearer through thought encoding, speech sound production, sound transmission, and sound processing.

What does articulatory phonetics concern?

The production of speech sounds.

What does acoustic phonetics concern?

The physical properties of sound waves.

What does auditory phonetics concern?

The perception of speech sounds.

What are active articulators?

Anatomical structures that move to create constrictions in airflow during speech.

What are passive articulators?

Stationary structures that serve as the point of contact for active articulators during speech.

What is the Source-Filter Theory?

It treats the speech production system as two components: the Source (vocal fold vibration) and the Filter (the vocal tract shaping sound).

How are vowels classified?

Based on tongue height, tongue advancement, lip rounding, and tenseness.

What are monophthongs?

Pure vowels where the tongue remains stationary.

What are diphthongs?

Vowels that involve a movement from one position to another within a single syllable.

How are consonants classified?

Using voicing, place of articulation, and manner of articulation.

What is voicing in the context of consonants?

The state of the glottis; voiced sounds have vibrating vocal folds, while voiceless sounds do not.

What are stops in consonant articulation?

Consonants produced by complete closure of airflow followed by a release.

What is the importance of understanding the Source-Filter Theory for Speech and Language Therapists (SLTs)?

It helps identify communication profiles and areas of breakdown in speech production.

What is transcription in phonetics?

The representation of speech sounds through phonemic, broad phonetic, or narrow phonetic models.
