Summary
Listeners perceive speech with hypernasality as more monotonous. This study investigated the link between hypernasality and intonation perception, finding increased hypernasality significantly lowered perceived intonation.
Area of Science:
- Speech Science
- Audiology
- Linguistics
Background:
- Anecdotal reports suggest hypernasal speech sounds monotonous.
- The relationship between hypernasality and intonation perception lacks empirical investigation.
Purpose of the Study:
- To investigate the effect of hypernasality on the auditory-perceptual ratings of speech intonation.
- To test the hypothesis that increased hypernasality leads to lower perceived intonation.
Main Methods:
- Simulated speech stimuli with varying levels of hypernasality and intonation.
- Auditory-perceptual ratings of intonation by 30 participants using a visual analogue scale.
Main Results:
- Significant main effects of both intonation and hypernasality were found.
- An interaction effect indicated that higher hypernasality levels were associated with lower intonation ratings.
- Speech was perceived as more monotonous with increasing hypernasality.
Conclusions:
- Hypernasality can significantly impact the perception of speech intonation, making it sound more monotonous.
- Instrumental measures are recommended to complement auditory-perceptual assessments of speech features.

01:21Perceiving Loudness, Pitch, and Location
1.0K
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

01:30Typical Model Studies
637
Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

01:21Antipsychotic Drugs: Typical and Atypical Agents
885
Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...

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.

The term self-esteem is often used generically, to refer to how people feel about themselves. However, according to research, there are three distinct constructs that should not be used interchangeably (Brown & Marshall, 2006).

01:43Gustation
52.4K
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.
