Computer-based auditory training improves second-language vowel production in spontaneous speech.

Area of Science:

• Second Language Acquisition
• Phonetics and Phonology
• Speech Technology

Background:

• Greek speakers often struggle with English vowel pronunciation due to phonetic differences.
• Auditory training is a potential method to improve non-native speech sound production.
• Computer-based training offers a scalable approach to language learning.

Purpose of the Study:

• To assess the impact of computer-based auditory training on Greek speakers' English vowel production.
• To evaluate the effectiveness of training in both read and spontaneous speech contexts.
• To determine if training benefits extend beyond controlled speech tasks.

Main Methods:

• A trained group of Greek speakers underwent computer-based auditory training.
• A control group of Greek speakers did not receive training.
• Vowel production was assessed pre- and post-training using English listener identification and acoustic analysis (F1/F2).

Main Results:

• The trained group showed significant improvement in English vowel production compared to controls.
• Improvements were observed in both read sentences and spontaneous speech.
• Enhancements were more pronounced in read sentences than in spontaneous speech.

Conclusions:

• Computer-based auditory training is effective for improving English vowel production in Greek learners.
• The training demonstrates ecological validity, benefiting spontaneous speech.
• Auditory training can enhance pronunciation skills beyond the level of read text.
