Kuaishou reduces the delay of live captioning to within 500 milliseconds: a self-developed end-to-end engineering paradigm that turns e-commerce live broadcast captions into real-time
The Kuaishou e-commerce live broadcast technology team has released the Live Captioning Engineering real-time captioning paradigm, upgrading from "caption output" to "real-time and accurate caption output": end-to-end delay is compressed from 1.5-2 seconds to 400-500 milliseconds, character error rate drops from 7.81% to 3.51%, and it supports tens of millions of concurrent connections, forming a systematic capability for high-concurrency e-commerce live broadcasting scenarios for the first time.
