iFlytek released SparkAudio 1.0, a foundational speech model that unifies complex audio understanding, emotion recognition, and real-time speaker separation, overcoming information loss in traditional cascaded architectures. The upgraded X2.6 series includes a 4B on-device model achieving ~70% of cloud capabilities with low latency. With voice LLM API calls surging over 20x year-on-year, this marks a shift from simple text transcription to multi-source acoustic-semantic joint reasoning.
