Voice Mode Test: ChatGPT and Gemini Detect Whispering, Grok Fails
deferare · reddit · 2026-08-28
The author tested whether ChatGPT, Gemini, and Grok voice modes could tell if they were being whispered to versus spoken to at normal volume.
ChatGPT and Gemini correctly identified whispering; Grok failed. The author suspects Grok converts speech to text first (STT), losing volume and prosody cues, while ChatGPT and Gemini process audio natively.
