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.
