Human or AI-generated voiceover for chemotherapy education video? Evidence from knowledge and practice tests improvement among cancer patients by pharmacists

BackgroundEducational videos play a crucial role in enhancing healthcare delivery. Developing an educational video designed to improve patient understanding of catastrophic treatment. During the video's creation, two voiceover methods were employed: human voices and artificial intelligence (AI)-generated voices. To date, the impact of voice-over origin-whether human or AI-on patient knowledge acquisition remains unexplored and warrants further investigation. This study aimed to assess the differences in knowledg…

In brief

Researchers compared three groups of cancer patients: a control group, one shown a chemotherapy education video with a human narrator, and one shown the same kind of video with an AI-generated narrator. All 129 participants completed a questionnaire on their understanding of chemotherapy.

The finding suggests that synthetic narration could be a workable way to produce patient education material in oncology pharmacy. The authors still report a consistent trend favoring human voices, and the text does not establish how durable the gains are or whether they hold in other settings.

Main points

  1. The study enrolled 129 cancer patients split into a control group, a human-voice video group, and an AI-voice video group.
  2. Topics assessed were chemotherapy administration procedures, treatment goals, and management of adverse drug reactions.
  3. Both video versions improved knowledge and attitude scores across all assessed topics.
  4. Human-voice videos showed a sustained trend toward higher knowledge and attitude scores.

The gain

Chemotherapy education videos narrated with AI-generated voices improved cancer patients' knowledge and attitudes across key topics, with no difference found between AI and human voice education.

The rundown

The study was framed as a case-control design with three arms, and a three-group quantitative comparison was used to examine knowledge and practice scores. Its stated aim was to fill a gap, since the effect of voiceover origin on patient learning had not been examined.

The authors recommend that both human- and AI-voiced videos be incorporated into the oncology healthcare system because of their effectiveness. They also suggest that combining a human voice with realistic scenario videos should be considered to help patients understand treatment more deeply.
