Study Notes

Phonetics

The study of speech sounds
Focuses on how sounds are produced, transmitted, and perceived

Spelling and Sound Reflection

Spelling does not always reflect pronunciation accurately
Phonetics provides a system for representing sounds consistently

International Phonetic Alphabet (IPA)

A standardized system for representing speech sounds
Uses symbols to represent each unique sound

Organs of Speech

The parts of the body involved in producing speech
Include the lungs, vocal cords, tongue, teeth, and lips

Speech Production

Consists of three stages: initiation, phonation, and articulation

Initiation

The process that sets the air in motion for speech
Involves expelling air from the lungs

Phonation

The process of creating sound using the vocal cords
Air flowing through the vocal cords causes them to vibrate

Articulation

The process of shaping the air stream into various sounds
Involves movement of the tongue, lips, and teeth

Place of Articulation for Consonants

Refers to the point of contact between the articulators (tongue, lips, teeth)
Examples include: bilabial (lips), alveolar (behind the teeth), velar (soft palate)

Manner of Articulation for Consonants

Refers to the way in which the airflow is obstructed
Examples include: stops (complete closure), fricatives (narrow passage), affricates (stop followed by fricative)

Describing a Consonant

Describe the place of articulation
Describe the manner of articulation

Manner of Articulation for Vowels

Refers to the position of the tongue and its height and backness in the mouth
Vowels are described as: high, low, front, back

Describing a Vowel

Describe the height of the tongue (high, mid, low)
Describe the backness of the tongue (front, central, back)
Describe the tension of the tongue (tense, lax)

Articulatory Phonetics

Studies how sounds are produced
Key areas of study:
- Place of Articulation: Where in the vocal tract the airflow is restricted (e.g., lips, teeth, alveolar ridge)
- Manner of Articulation: How the airflow is constricted (e.g., stops, fricatives)
- Voicing: Whether vocal cords vibrate during pronunciation (e.g., voiced vs. voiceless)

Acoustic Phonetics

Studies the physical properties of speech sounds
Key areas of study:
- Frequency: The pitch of a sound
- Amplitude: The loudness of a sound
- Spectrograms: Visual representations of sound frequencies over time

Phonetic Transcription

A system for representing sounds visually.
Common systems:
- IPA (International Phonetic Alphabet): Widely used, includes symbols for all phonemes
- Phonemic Transcription: Broad transcription, focusing on distinctive sounds (phonemes)
- Phonetic Transcription: Narrow transcription, includes allophonic details and actual pronunciations

Auditory Phonetics

Examines how sounds are perceived by the ear
Key areas of study:
- Sound Perception: How listeners distinguish between sounds
- Psychophysics: Studies the relationship between physical stimuli and sensory perception

Phonetic Variation

Refers to differences in pronunciation among speakers or dialects.
Influential factors:
- Geographical Variation: Accents and dialects vary by region
- Social Variation: Variations based on sociolects, age, gender, and identity
Types:
- Allophonic Variation: Production of phonemes that may vary in context but do not change meaning
- Dialectal Variation: Differences in phonemes and their usages in different communities

Description

This quiz covers the fundamentals of phonetics, exploring how speech sounds are produced, transmitted, and perceived. It delves into the International Phonetic Alphabet (IPA), the organs of speech, and the processes involved in speech production. Test your knowledge about the initiation, phonation, and articulation stages of producing sounds.
