DonorRank: Donor Language Selection for Low-Resource Cross-Lingual Speech Recognition
Akriti Dhasmana, Aarohi Srivastava, David Chiang
Low-resource automatic speech recognition (ASR) commonly relies on cross-lingual transfer, where models are adapted from higher-resource donor languages. However, selecting donors…
Different Perturbations, Different Mechanisms: Understanding Continued Pre-training for Zero-Shot Dialect Robustness
Aarohi Srivastava, David Chiang
Dialectal variation remains a major challenge for multilingual language models. Perturbation-based continued pre-training (CPT) has emerged as a promising approach to improving rob…
IDIOLEX: Unified and Continuous Representations for Idiolectal and Stylistic Variation
Anjali Kantharuban, Aarohi Srivastava, Fahim Faisal +5
Existing sentence representations primarily encode what a sentence says, rather than how it is expressed, even though the latter is important for many applications. In contrast, we…
Dialect Matters: Cross-Lingual ASR Transfer for Low-Resource Indic Language Varieties
Akriti Dhasmana, Aarohi Srivastava, David Chiang
We conduct an empirical study of cross-lingual transfer using spontaneous, noisy, and code-mixed speech across a wide range of Indic dialects and language varieties. Our results in…
