- This means that speech is inherently variable, and its properties cannot be simply defined in a linear
manner.
Speech Signal Processing
- Perceptual Normalization:
✔️ The process by which a listener simplifies speech processing to smooth out superfluous variability.
- Listeners tend to adjust their perception to account for variability in speech, helping them understand
it better despite fluctuations.
Types of Perception
- Quantal Perception in Speech:
✔️ Categorical perception.
- Listeners categorize sounds into discrete groups, which helps in distinguishing phonemes effectively.
Duplex Perception
- Duplex Perception:
✔️ Syllable components are presented separately but simultaneously to each ear.
- This phenomenon allows listeners to perceive both the acoustic properties of syllables and the
interaction of the two components.
The McGurk Effect
- McGurk Effect:
✔️ The place and/or manner of articulation is perceived to change.
- This effect illustrates how visual information (like lip movements) can influence auditory perception,
leading to a mismatch between what one hears and sees.
