    Study Notes

    SPEECH PRODUCTION

    • Sounds of Speech: Phonemes

      • Phoneme: smallest unit of sound, changing it alters meaning.
      • International Phonetic Alphabet (IPA): symbols represent different speech sounds.

    • Producing Sounds of Speech

      • Speech begins with exhaled air from lungs.
      • Trachea (windpipe) and Larynx (voice box) are involved.
      • Vocal folds (vocal cords):
        • Relaxed and open: air passes silently.
        • Tensed and vibrating: air creates sound.
        • Frequency varies by size/thickness of folds and larynx size/shape.
          • Male: 85-180 Hz
          • Female: 165-255 Hz
      • Pharynx: upper part of throat.
      • Uvula: flap of tissue at the back of the soft palate.

    • Speech Sounds:

      • Vowels: unrestricted air flow through the pharynx and oral cavity.
        • Harmonics (multiples of fundamental frequencies) are present.
        • Jaw position shapes oral cavity, affecting resonance and frequency.
        • Formants: specific frequency bands with high amplitude in vowel sound spectra.
      • Consonants: restricted air flow along the path from vocal cords.
        • Place of articulation: location of restriction.
        • Manner of articulation: nature of restriction.
        • Voicing: whether vocal folds vibrate or not.

    Perceiving Speech

    • Difficulties in Translating Speech to Phonemes in the Brain
      • No 1-to-1 correspondence.
      • Speaker variations in fundamental frequency and dialect.
      • Differences in phonemes over time (whisper, shout, etc.).

    Categorical Perception of Phonemes

    • Categorical Perception: Perceptual response to stimuli in categories.
      • Changes in perception occur abruptly.
    • Voice Onset Time (VOT): Time between burst of sound and onset of voicing.
      • Influences perception of voiced vs. voiceless consonants.
    • Phonemic Boundary: VOT point where perception of consonants changes abruptly.

    Vision and Speech Perception

    • McGurk Effect: Vision influences speech perception.
    • Conflicting visual/auditory stimuli cause the perception to compromise.

    Knowledge and Speech Perception

    • Knowledge of grammar and context shapes speech understanding.

    MUSIC PRODUCTION

    • Dimensions of Music

      • Pitch: The fundamental dimension distinguishing compositions.
      • Octave: A sequence of notes where the last note is twice the fundamental frequency of the first.
        • Tone chroma (pitch within an octave)
        • Tone height (position within an octave)
        • Semitones: 12 intervals/octave that are perceptually equal.
      • Loudness (dynamics): Variation in loudness throughout the piece.
      • Rhythm: Temporal patterns.
      • Tempo: Overall pace.
      • Beat: Equally spaced pulses.
      • Meter: Patterns of beats.
      • Timbre: Differences in sound despite same pitch and loudness.
      • Melody: Sequence of notes perceived as a single unit by the listener.

    • Scales and Keys

      • Scale: Particular group of notes in an octave.
      • Consonance: Pleasant combinations of notes.
      • Dissonance: Unpleasant combinations of notes.

    • Knowledge and Music Perception

      • Accumulated knowledge.
      • Implicit knowledge of how language or musical patterns work.

    • Neural Basis of Music Perception

      • Auditory cortex plays a role.
        • Left hemisphere for time-related aspects.
        • Right hemisphere for pitch-related aspects.

    • Amusia: An impairment in musical perception and/or production.

    • Application

      • Automatic speech recognition uses accurate perception of human speech by machines.
