Best Open Speech Recognition (ASR) Models in 2026: WER, Languages, Latency, and License Compared

The open speech recognition landscape has diversified beyond the previous industry standard, with models like Cohere Transcribe, IBM Granite Speech 4.1, ARK-ASR, and MOSS-Transcribe now performing at nearly identical accuracy levels. As performance differences on the Hugging Face Open ASR Leaderboard have narrowed to less than one word error rate point, technical selection now depends on factors like language support, latency, and licensing rather than singular model superiority.
