- What it is
- An analysis of large-scale logs from a mobile search service that showed when people chose to speak a web query and when they typed it. It found that longer queries were more likely to be typed, which the authors had not expected.
- How much weight it carries
- Peer-reviewed at Interspeech and based on a large log sample from 2010. It describes web search queries on early mobile voice input, not chatbot prompts, so it shows how people chose between speaking and typing, not what the best prompt length is.
Facts taken from this source
- In logs of a 2010 mobile search service, longer queries had a higher probability of being typed than shorter ones, which the authors said was contrary to their expectation.
“We also find, contrary to our intuition, that longer queries have a higher probability of being typed than shorter queries.” (Abstract)
