Distant conversational speech recognition: Challenges and Opportunities

From Microsoft Research

Host: Sunit Sivasankaran, Microsoft Research Speaker: Dr. Samuele Cornell, Carnegie Mellon University State-of-the-art ASR systems excel on close-talk benchmarks but struggle with far-field conversational speech, where error rates remain above 20%. Current benchmark datasets inadequately assess generalization across domains and real-world conditions, often relying on oracle segmentation that yields overly optimistic results. Distant ASR (DASR) faces unique challenges including overlapping spe...
