Echo01:06

Echo

635
The human ear cannot distinguish between two sources of sound if they happen to reach within a specific time interval, typically 0.1 seconds apart. More than this, and they are perceived as separate sources.
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case,...

Hearing01:31

Hearing

53.5K
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Larynx01:21

Larynx

2.3K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Language Development01:22

Language Development

501
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Auditory Perception01:17

Auditory Perception

647
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Fixed Action Patterns01:06

Fixed Action Patterns

16.6K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Area of Science:

  • Linguistics
  • Speech Science
  • Acoustic Phonetics

Background:

  • Vocal fry is prevalent in speech and may impact psychosocial well-being and vocal health.
  • Identifying vocal fry patterns aids in understanding phonatory function, linguistic variations, and clinical applications.

Purpose of the Study:

  • To investigate and categorize the different patterns of vocal fry observed in running speech.

Main Methods:

  • Analysis of the Rainbow Passage read by five healthy young females.
  • Utilized Praat software for audio and text grid creation.
  • Visual and perceptual examination of audio signals and spectrograms to identify vocal fry patterns based on acoustic transients and fundamental frequency.

Main Results:

  • Identified six vocal fry patterns: single pulse (FRY1), double pulse (FRY2), multiple pulse (FRY3), period doubling (FRY4), inaudible (FRY5), and indeterminate (FRY6).
  • Single pulse vocal fry constituted 76% of occurrences, followed by period doubling (13%).
  • Vocal fry patterns appeared at syllable onset (36%), early syllable (26%), late syllable (25%), and syllable end (13%).

Conclusions:

  • Vocal fry is a complex phenomenon with identifiable patterns.
  • Distinguishing these patterns is essential for understanding their glottal adductory nature and phonatory function.
  • Further research is needed to explore additional categories, individual variations, and the physiological and perceptual aspects of vocal fry.
