22. Limitations
• Data collected in 2018; may not reflect recent algorithm
updates
• Scoring rubric has not been assessed for reliability and
may need future refinements
• May not reflect real use cases that incorporate tailored
search results
• Overall scores for all assistants may have been lower if
prioritizing audio only output
26. Conclusions
• Siri and Google provided evidence-based links; little
audio output
• Alexa was worst at natural language comprehension;
high audio output
• Many information providers are entering voice
information provision via traditional websites and
third-party apps
• Information professionals should push for better
usability and increased transparency about health
information partnerships
