Unverified50% confidenceSolutionExact time
In always-listening offline voice systems, the keyword model typically outputs scores frame by frame or over a fixed sliding window; a single frame exceeding the threshold does not mean the complete phrase was spoken, and confirmation across consecutive frames (e.g., 3-5 consecutive frames above threshold) and a cooldown period (ignoring retriggering of the same keyword within a few hundred milliseconds) are needed.

UnverifiedStreaming processing divides audio into smaller time windows (typically 200–500 milliseconds), performing recognition and translation as audio is received, which significantly reduces Time to First Token.75% similarUnverified传统语音AI采用串行管线设计，即VAD→ASR→LLM→TTS四个独立模块依次传递数据，每个环节引入约100-300毫秒延迟，四段叠加总延迟往往超过1秒72% similarUnverifiedEnd-to-end voice processing architectures process audio tokens directly within a unified model, with theoretical latency compressible to within 200ms.72% similarUnverifiedNon-streaming encoders can use bidirectional attention or global convolution, generating representations after seeing the complete speech sequence, and typically achieve higher accuracy.72% similarUnverified端到端大模型由统一的多模态模型直接完成从语音输入到语音输出的全过程，规避流水线架构的信息损耗与累积延迟71% similar
