Voice Ask is live: why is Xiaohongshu pushing search-by-question?

语音问一问上线，小红书为何发力问搜？

Xiaohongshu fully launched Voice Ask on Jan. 27, letting users long-press to speak on the search page and get structured answers distilled from in-app user experience posts. The post says it can handle 3-minute spoken queries, foreign languages, and dialects, but does not disclose the model, ASR stack, latency, or accuracy. The real shift is from 3-4 character keyword search to longer spoken questions, widening search intent capture and scenario coverage.
