On June 4, iFLYTEK’s Spark VoiceWise AI voice interaction product underwent a significant upgrade, introducing a high-performance CPU-based ASR engine and full-duplex voice interaction capabilities. This new engine supports both online short audio recognition and offline recording file recognition, running efficiently on standard CPUs and compatible with Kunpeng ARM architecture and Kylin Linux. It is tailored for domestic infrastructure needs in industries such as finance, government, telecommunications, and energy. On the same configuration of Kunpeng ARM servers, the new engine increases online short audio recognition concurrency by approximately 90% and overall offline recording file throughput by about 150% compared to the traditional CPU version.
