Learning foreign sounds in an alien world: videogame training improves non-native speech categorization.

Area of Science:

• Psycholinguistics
• Auditory Perception
• Second Language Acquisition

Background:

• Speech perception relies on multiple acoustic dimensions, with native language phonology influencing non-native speech processing.
• Sound category learning is affected by experienced sound distributions, influencing perceptual cue weighting.

Purpose of the Study:

• To investigate how sound distribution characteristics influence perceptual cue weighting in native Japanese speakers learning English /r/-/l/ categories.
• To evaluate the effectiveness of a videogame-based training paradigm for improving non-native speech perception.

Main Methods:

• A videogame paradigm was used for training, integrating sound categories with visual information and player responses.
• Participants trained for 2.5 hours over 5 days, with no explicit categorization feedback.

Main Results:

• Participants showed significant improvements in English /r/-/l/ perception, comparable to 2-4 weeks of explicit training.
• A shift towards more native-like perceptual cue weights was observed in the trained participants.

Conclusions:

• Implicit, videogame-based training can effectively enhance non-native speech perception and modify perceptual cue weights.
• This approach offers a promising alternative to explicit methods for second language phonological learning.
