Hugging Face Benchmarks Frontier ASR on Code-Switched Bilingual Speech

Hugging Face Blog·medium signal

ServiceNow AI researchers published a Hugging Face benchmark testing whether frontier automatic speech recognition systems can handle code-switching — customers mixing two languages mid-sentence — a common real-world failure mode for voice agents. The study evaluates how well current ASR models transcribe bilingual speech and where they break down. Directly relevant for anyone building production voice agents for multilingual user bases.
