Phonetic compliance: a proof-of-concept study.

Area of Science:

• Linguistics
• Second Language Acquisition (SLA)
• Phonetics and Phonology

Background:

• Phonetic compliance, the intrinsic ability to produce non-native speech sounds, is vital for L2 phonetics and phonology acquisition.
• Understanding phonetic compliance is essential for controlling variables in SLA experimental studies.

Purpose of the Study:

• To introduce and define the concept of phonetic compliance.
• To test the feasibility of assessing phonetic compliance using a gradient measurement.
• To develop initial indicators for assessing phonetic compliance.

Main Methods:

• A two-fold proof-of-concept study was conducted.
• Study 1 involved native French speakers reproducing unusual vowels and aspirated stops.
• Study 2 collected L1-typical realizations to refine assessment indicators.

Main Results:

• Descriptive statistics were used to analyze pilot data in Study 1.
• A preliminary set of indicators for assessing phonetic compliance was developed in Study 2.
• The study demonstrated the feasibility of gradient assessment for phonetic compliance.

Conclusions:

• Phonetic compliance is a significant factor in SLA, influencing L2 phonetic and phonological acquisition.
• The proof-of-concept study provides a foundation for developing a reliable and valid test of phonetic compliance.
• Further research is needed to refine the assessment and validate the concept of phonetic compliance.
