Open the original- What it measures
- The study looked at when people chose to speak a web search query on a mobile phone and when they typed it, using large-scale logs.
- What it does not show
- Web search queries from 2010, not chatbot prompts. It shows that people did not simply speak their longest queries, which is a reason not to assume that voice always gives longer input.
