Researchers have developed Vividh-ASR, a new benchmark designed to evaluate automatic speech recognition (ASR) models on Indic languages, specifically Hindi and Malayalam. This benchmark categorizes audio into four tiers: studio, broadcast, spontaneous, and synthetic noise, to better diagnose performance issues with low-resource languages. Their study revealed that optimizing learning-rate timing and curriculum ordering significantly improves performance, particularly for spontaneous speech. They also introduced a parameter-efficient fine-tuning technique called reverse multi-stage fine-tuning (R-MFT), which allows smaller models to match or surpass larger conventionally fine-tuned models.
