code-switching

ServiceNow released AU-Harness, the first comprehensive benchmark for code-switched speech recognition in enterprise voice agents, testing seven ASR systems including ElevenLabs, Gemini, and AssemblyAI. The benchmark covers 918 utterances across Spanish-English, French-English, Canadian French-English, and German-English, measuring Word Error Rate (WER), Semantic WER (SWER), and Answer Error Rate (AER). ElevenLabs Scribe V2 achieved the lowest WER across all language pairs, followed closely by AssemblyAI Universal-3 Pro.
