Phonetics Lecture Notes
Overview of the Session
Focus on six main concepts discussed during the lecture regarding phonetics and diacritics.
Importance of taking notes highlighted for effective learning.
Key Concepts Introduced
Coarticulation
Definition: Coarticulation refers to the phenomenon where a speech sound is altered due to the influence of neighboring sounds.
Example: In the word "mean," the vowel 'e' becomes nasalized due to the surrounding nasal sounds.
Occurs in both disordered and typical speech.
The rapid rate of speaking can enhance the degree of coarticulation, often making it challenging for non-native speakers to discern word boundaries when listening to fast speech in foreign languages.
Narrow vs. Broad Transcription
Narrow transcription uses brackets [ ] and captures exact pronunciations, including variations due to coarticulation.
Example: "How are you doing?" versus "How you doing?").
Broad transcription uses slashes / / and reflects expected pronunciations without detailed variation.
Important for accuracy, especially in clinical phonetics where detail can influence diagnosis and intervention.
Syllabic Consonants
Definition: A syllabic consonant can function as the nucleus of a syllable, similar to a vowel.
Examples of syllabic consonants in English:
/l/ as in "fiddle"
/m/ as in "chasm"
/n/ as in "kitten"
The presence of a diacritic mark (a small vertical line beneath the consonant) indicates that the consonant is syllabic.
Components of Syllables
Vowels serve as nuclei for syllables, while syllabic consonants can take on this role in specific instances.
Total syllables in words: Focus on the number of vowel sounds to count syllables.
Flap Tap vs. Glottal Stop
Flap (or Tap)
Definition: A flap is a quick phonetic articulation of a /t/ or /d/ sound characterized by a brief contact of the tongue with the alveolar ridge.
Example: "Water" is often pronounced as "wader" where the /t/ becomes a flap.
Characteristics: Flaps often occur intervocalically (between two vowels) and are voiced.
Recording of Example: Say "water" and notice the difference between "water" and "wader."
Glottal Stop
Definition: A glottal stop is produced in the glottis and is voiceless. It can also affect the pronunciation of /t/ in specific phonetic environments.
Example: In the word "kitten," the /t/ often turns into a glottal stop (not fully articulated).
Placed Environment: Usually occurs before a syllabic /n/ sound.
Importance in Differentiation: Knowing the difference between these articulations is crucial in phonetic transcription and in understanding how phonemes can vary in realization.
Aspirated vs. Unreleased Stops
Aspirated Stops
Definition: An aspirated stop is a voiceless plosive with a burst of air following it, noticeable when pronounced in a stressed syllable.
Voiceless Stops in English: /p/, /t/, /k/
Example: Say "pop" versus "spop," where the latter lacks aspiration due to the preceding [s].
Transcription: Aspirated stops are indicated with a superscript /h/ (e.g., [tʰ] in "top").
Unreleased Stops
Definition: These are stops that do not have the full articulatory release associated with aspiration.
Occur at the end of words and can be produced with or without released aspiration, resulting in allophonic variations.
Example: In words like "hop," it may be said with a subtle release or no release depending on the speaker's expressiveness.
Velarization
Definition: Velarization involves the raising of the back of the tongue while producing an /l/ sound, typically occurring when the /l/ follows a vowel in a coda position or at the end of a word.
Example: "Deal" vs. "Lead"
"Deal" has the dark /l/ (velarized), while "Lead" has a clear /l/ sound.
Transcription: The velarized /l/ is indicated by a diacritic mark (often appearing as an /l/ with a little tilde/belt).
Summary of Important Concepts
Coarticulation: Understanding this is fundamental to grasping variations in speech sounds.
Narrow vs. Broad Transcription: Essential for achieving accurate phonetic understanding and transcription practices.
Syllabic Consonants: Recognition of which consonants can function as syllables within English is crucial for transcription.
Flap and Glottal: Knowing the variance in these sounds helps improve both pronunciation and transcription accuracy.
Aspiration: Awareness of stress and phonetic positioning can impact how sounds are produced and perceived.
Velarization: Understanding this is key in appreciating how sounds might alter contextually.
Questions and Clarifications
Students are encouraged to ask questions throughout to clarify concepts as they arise.
Example vocab:
"Cranky" might be pronounced differently based on nasality influenced by neighboring sounds.
Conclusion
Aim was to explain these concepts clearly and effectively to enable students to feel confident in their knowledge of diacritics and phonetic transcription nuances.
Continued practice and interaction are encouraged for mastering these areas of phonetics and phonology.
