A Cross-lingual Comparison of Human and Classification Model Entrainment Behavior in Code-switched Speech Settings
Quick Answer
This study analyzes conversational entrainment in code-switched speech across Mandarin-English, Hindi-English, and Spanish-English dialogues, revealing that while lexical entrainment is consistent, acoustic-prosodic features vary contextually.
Quick Take
Classification models, including classical and Transformer-based classifiers, detect entrainment but prioritize different features than humans, highlighting challenges for developing naturalistic conversational agents.
Key Points
- Lexical entrainment is consistent across language pairs in code-switched speech.
- Acoustic-prosodic entrainment shows significant context-specific variation.
- Classical and Transformer classifiers detect entrainment but misprioritize features.
- Study introduces a human-grounded framework for evaluating multilingual models.
- Findings suggest challenges for creating naturalistic code-switched conversational agents.

Source Excerpt
Conversational entrainment is well-studied in monolingual and written contexts, but remains underexplored in spoken code-switching (CSW). We present a novel cross-lingual analysis of entrainment in Mandarin-English, Hindi-English, and Spanish-English dialogue and show that, while lexical entrainment generalizes across language pairs, entrainment over acoustic-prosodic and CSW style aspects exhibits context-specific variation. We build on these findings by asking whether classification models cap
