    Together AI 如何构建全球最快的语音转文字技术栈

    Together AI 优化 ASR 全链路,使 NVIDIA Parakeet-TDT 0.6B v3 可在不到 10 秒内转录约 20 小时语音,并与 OpenAI Whisper Large v3 一同成为 Artificial Analysis 排名中延迟最低的两款模型。其方案采用多配置 TensorRT、条件 CUDA 图、Unix 域套接字、共享内存和 epoll,解码器提速 2–3 倍。通过 gc.freeze() 排除预分配对象的 GC 扫描后,约 200 ms 的 p95 延迟尖峰也随之消失。

For streaming ASR, that predictability matters because delayed partial transcripts can make a voice system feel slow even when average latency looks fine. Under load for streaming workflows, p50 and p90 latency looked healthy, but p95 would periodically spike by about 200 ms. The logs showed small queue depth and normal GPU times, but CPU functions that normally ran in under 5 ms suddenly took over 100 ms. Something in the background was stealing
