Spark-Audio 1.0 - Acoustic Low-volume speech: leaderboard
Spark-Audio 1.0 release checkpoint after its second distillation epoch. Native audio-to-text and text evaluations use each task’s published metric. In-house recognition and spoken interaction use separate in-house populations. IFEval and IFBench measure instruction-level accuracy; HumanEval measures pass@1. Encoder adaptation ablations are separate from the released model. CER (%).
Metric: CER (%). Source: arxiv.org. Saturation forecast: Around August 2027. 4 models tracked.
