L1 Framing Typology and Acoustic Differences in L2 Speech: Insights From Motion Constructions

Area of Science:

• Linguistics
• Second Language Acquisition
• Phonetics and Phonology

Background:

• Languages exhibit diverse 'framing typologies' in constructing motion events, influencing conceptualization.
• Conceptual transfer from L1 framing typology to L2 has been observed in grammar and gestures.
• The impact of L1 framing typology on L2 acoustic speech production remains largely unexplored.

Purpose of the Study:

• To investigate whether L1 framing typology affects the acoustic properties of L2 English speech.
• To compare acoustic features in L2 English produced by speakers with V-framed (Korean, Turkish) and S-framed (German, English) L1 backgrounds.
• To determine if acoustic differences in L2 speech are attributable to conceptual transfer or articulatory variations.

Main Methods:

• Analysis of read speech corpora from L2 English speakers with V-framed and S-framed L1s.
• Extraction and analysis of acoustic measurements including duration, pitch, and intensity.
• Comparison of acoustic data between L1 background groups and native English speakers.

Main Results:

• No significant acoustic differences were found between L2 English speakers based on V-framed versus S-framed L1 backgrounds.
• Distinct acoustic differences were observed between native and non-native English speakers.
• Post hoc analyses detailed specific acoustic variations between native and non-native L2 English speakers.

Conclusions:

• L1 framing typology does not appear to significantly influence the acoustic realization of L2 English speech.
• Conceptual transfer of framing typology is not readily observable in the acoustic domain of L2 speech production.
• Observed differences in L2 English speech production are better explained by articulatory variations between native and non-native speakers.
