Summary
Immediate auditory feedback helps regulate precise articulatory timing. This research shows that hearing oneself speak is crucial for coordinating speech movements and maintaining phonetic structure.
Area of Science:
- Speech production and acoustics
- Auditory feedback mechanisms
- Phonetic structure instantiation
Background:
- Talkers precisely coordinate articulator timing across speech rates and stress.
- This coordination instantiates phonetic structure in the acoustic signal.
Purpose of the Study:
- To test if immediate auditory feedback regulates articulatory timing control.
- Investigate the role of auditory signals in maintaining precise inter-articulator timing.
Main Methods:
- Electromagnetic articulography (EMA) recorded 480 /tV#Cat/ utterances.
- Varied V (/ɑ/-/ɛ/), C (/t/-/d/), speech rate (fast-normal), and stress.
- Compared unmasked (auditory feedback) and masked (no feedback) listening conditions.
Main Results:
- Shorter jaw cycles reduced tongue-tip latency onset across conditions.
- Tongue-tip latencies were strongly linked to utterance type without masking.
- Auditory masking weakened the affiliation between tongue-tip latencies and utterance type.
Conclusions:
- Talkers utilize real-time auditory signals to regulate inter-articulator timing precision.
- Auditory feedback is essential for maintaining phonetic structure during speech production.

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.

01:13The Cochlea
44.6K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

01:15Auditory Pathway
5.3K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

01:24Effects of feedback
527
Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
