My Voice as a Daily Reminder: Self-Voice Alarm for Daily Goal Achievement

Document Information

• Subject Area: Human-Computer Interaction (HCI), Mobile App Design, Habit Formation
• Keywords: Self-voice, Daily Reminder, Mobile Alarm Design, Habit Formation, Language Learning

Research Background and Problem

• Research Problem or Challenge: Many individuals struggle to adhere to and complete their daily plans due to distractions from other tasks or activities. Additionally, existing research rarely focuses on the impact of alarm sound types on task completion.
• Significance: Establishing daily plans not only helps individuals achieve long-term goals but also promotes habit formation and improves task completion efficiency. However, achieving behavioral change and habit execution remains a persistent challenge.
• Research Motivation and Related Work:
  • Mobile technologies have introduced new intervention methods, such as using smartphone reminders or alarms to help users focus on daily tasks.
  • Meanwhile, psychological and neuroscience studies suggest that humans tend to pay more attention to and have stronger emotional responses to self-relevant information (e.g., their own voice). However, this strategy has not been fully explored or applied in human-computer interaction.

Solution

• Proposed Solution: Develop a "self-voice alarm" system that uses personally recorded voice messages as reminders for daily goal tasks.
• Innovations:
  • Leverage the psychological effect of self-relevant information to explore whether self-voice can enhance task completion and daily behavior automation.
  • For the first time, compare the psychological and behavioral impacts of self-voice, other voices, and electronic beep alarms over long-term use.
• Implementation Steps and Key Technologies:
  1. Developed a mobile application that allows users to set daily reminders and supports the completion of English vocabulary learning tasks.
  2. Designed an experiment dividing participants into three groups using self-voice alarms, other voice alarms, and electronic beep alarms, measuring subsequent behavioral and psychological changes.
  3. Collected data including reaction time, task completion frequency, learning repetition count, and subjective user evaluations of the alarm system.

Research Outcomes

• Specific Findings:
  • Participants in the self-voice alarm group demonstrated a higher daily task completion rate (13.14 days, compared to 10.8 days and 9.14 days for the other voice and beep alarm groups, respectively).
  • Self-voice alarms significantly increased task repetition frequency, with an average of 14 repetitions per day, higher than the beep alarm group’s 9.71 repetitions.
  • Voice alarms (including self-voice and other voice alarms) had a positive impact on behavioral automation and perceived usefulness.
• Advantages Compared to Existing Solutions:
  • Compared to traditional beep alarms, voice alarms (especially self-voice alarms) better promote task completion and behavioral automation.
  • Users were more likely to perceive the system as helpful for their learning goals when using voice alarms.
• Experiment or Evaluation Results:
  • Self-voice alarms elicited higher alertness but also caused some discomfort and emotional reactions (e.g., embarrassment, nervousness).
  • Other voice alarms performed better than self-voice alarms in enhancing task enjoyment.
• Limitations and Future Directions:
  • The experiment lasted only 14 days, making it difficult to fully observe the impact of alarms on long-term habit formation; future studies should consider longer durations.
  • Further research is needed to examine how different voice characteristics (e.g., familiarity) affect user behavior and alarm effectiveness.
  • More personalized design options (e.g., volume adjustment, content variation) should be explored to reduce negative emotional experiences when using alarms in public settings.

Discussion and Practical Application Suggestions

• Practical Design Recommendations:
  1. Source Selection: Provide users with personalized options, including customizable alarm sound types (e.g., self-voice or other voices) and volume adjustment features, with the ability to switch to vibration mode based on environmental conditions.
  2. Contextual Adaptability: Design self-voice alarms for the initial stages of behavior change, while using other voice alarms during the habit formation phase to maintain task enjoyment.
  3. Voice Parameter Adjustment: Modify the pitch or tone of the voice to enhance user adaptability and preference for the sound.
• Future Research Directions: Extend the study duration to observe effects during the habit execution phase; investigate the potential of familiar voices (e.g., family or friends) as new alarm types; explore how voice content and non-verbal signals influence user behavior.
