Summary
Visual feedback using an electromagnetic articulometer helps Japanese learners improve American English vowel pronunciation. This method trains articulatory adjustments to match target sounds, proving effective for second language (L2) pronunciation learning.
Area of Science:
- Second Language Acquisition
- Speech Science
- Educational Technology
Background:
- Articulatory information aids second language (L2) pronunciation.
- Effective methods for L2 pronunciation remediation are crucial.
- Visual feedback can enhance learning by providing real-time articulatory guidance.
Purpose of the Study:
- To investigate an electromagnetic articulometer-based visual-feedback approach for L2 pronunciation learning.
- To train learners to adjust articulatory positions to match real-time targets for L2 vowels.
- To assess the effectiveness of visual training for improving pronunciation of specific L2 vowels.
Main Methods:
- Utilized an electromagnetic articulometer to provide real-time articulatory targets.
- Trained Japanese learners on the American English vowel /æ/.
- Included visual training, with some participants also receiving audio training.
- Estimated L2 vowel targets from productions overlapping in both L1 and L2.
Main Results:
- Visual training significantly improved pronunciation of the American English vowel /æ/ for Japanese learners.
- The inclusion of audio training alongside visual training did not yield further significant improvements.
- Articulatory visual feedback demonstrated effectiveness in facilitating L2 pronunciation learning.
Conclusions:
- Articulatory visual feedback is an effective method for L2 pronunciation learning.
- Real-time visual targets aid learners in adjusting articulatory positions.
- This approach shows promise for remediating pronunciation difficulties in second language learners.

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...

01:24Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Non-verbal communication extends beyond gestures and facial expressions to include vocal elements known as paralanguage. Paralanguage consists of non-verbal vocal cues such as pitch, loudness, speech rate, pauses, and non-verbal vocalizations like laughter, sighs, and moans. These elements not only accompany speech but also provide critical emotional and contextual information.The Role of Paralanguage in CommunicationParalanguage adds depth to spoken language by conveying emotions and...

01:17Auditory Perception
1.5K
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...

1.3K
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...

Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...
