Generative Artificial Intelligence

Use Case: Oral Presentation Coaching with Yoodli

Pain Points: 

Unclear task division, disjointed speaking rhythm, and limited collaborative practice opportunities.
 
Yoodli Solution:
  1. Role Division Simulation & Real-Time Feedback
    1. Upload your group’s PPT outline to Yoodli, select the “Academic Presentation” scenario, and customise the goal as “3-person collaborative presentation (1 key section per person)”.
    2. Enable Multi-Player Mode to assign roles (e.g., lead presenter, data analyst, case study explainer) and simulate the actual presentation flow. Yoodli tracks each member’s fluency, time allocation (e.g., “Alice exceeded 1 minute on the methodology section”), and generates a team collaboration report (e.g., “Limited interaction between members—suggest adding transitional eye contact”).
    3. Pro Tip: Use Yoodli’s “Screen Sharing” feature to display the PPT synchronously. The AI will provide content-specific feedback (e.g., “Add data source citations for Slide 5”) alongside delivery feedback.
  2. Stress Testing & On-the-Spot Adaptability
    1. Simulate the Q&A session: Yoodli generates 5–8 high-frequency questions (e.g., “Is your experimental sample size sufficient?”). Team members take turns answering, and the AI evaluates response logic and completeness (e.g., “Bob’s answer strayed from the core—suggest restating the question before expanding”).
    2. Outcome: After 3 practice sessions, the team’s overall fluency improved by 40%, and question-answering accuracy rose from 60% to 90%.
Step-by-Step Template:

Step 1: Sign up for Yoodli (free) and create a group channel. 

Step 2: Upload the PPT outline, set the scenario to “Group Presentation – [Your Subject, e.g., Sociology]”. 

Step 3: Assign roles and record a practice video (3 minutes per member). 

Step 4: Review the team report and prioritize improvements: - Transitional phrases between members (e.g., “Next, Lily will walk through our experiment results”). - Conversational expression of data visuals (e.g., “Figure 3 shows a 20% increase—avoid reading slide text directly”). 

Step 5: Simulate Q&A using the AI-generated question bank. Track each member’s response time and keyword coverage.

Use Case: Excel at Thesis Defences with Yoodli

Pain Points: 
Obtuse academic terminology, unclear logical flow, and insufficient preparation for committee questions.
 
Yoodli Solution:
  1. Content Depth Optimisation
    1. Upload your full thesis PDF to Yoodli (supports text analysis), select the “Thesis Defence” scenario, and set the goal as “Clearly communicate research innovations”.
    2. The AI analyses alignment between your PPT and thesis (e.g., “Slide 8’s conclusion does not echo the research hypothesis in the introduction”) and offers conciseness suggestions (e.g., “Condense the methodology section from 4 to 2 slides—focus on experimental design”).
    3. Pro Tip: Enable “Keyword Reminder” to get real-time pop-up alerts if you omit core terms (e.g., “machine learning model”) during your speech.
  2. Full Defence Simulation
    1. Generate 3 AI judges (professor, industry expert, interdisciplinary scholar) with customised questioning preferences (e.g., “Professor focuses on theoretical contributions; expert emphasises practical value”).
    2. During practice, Yoodli simulates judge interruptions (e.g., “How does your research differ from Smith’s 2020 findings?”) and evaluates academic rigour (e.g., “Use of ‘significantly improved’ requires p-value”).
    3. Outcome: After 5 simulations, defence duration was reduced from 15 minutes over the limit to on-time completion, and academic depth scores increased by 35%.
Step-by-Step Template:

Step 1: Sign up for Yoodli, select the “Thesis Defense” template, and upload your PPT and abstract. 

Step 2: Configure AI judge parameters (e.g., “3 judges, moderate question difficulty”). 

Step 3: Record a practice video (15-minute presentation + 10-minute Q&A). 

Step 4: Review the content analysis report and prioritize improvements: - Accessible expression of research significance (e.g., “Replace ‘fills theoretical gaps’ with ‘provides new solutions for XX field’”). - Logical transition words (e.g., “However… Therefore… In conclusion”). 

Step 5: Draft 3 versions of responses to high-frequency AI-generated questions (e.g., “What are the limitations of your research?”) and compare feedback.

Tips for Students

  1. Progress Tracking: Use the dashboard to monitor improvements (e.g., “62% reduction in filler words over 1 month”) and share PDF reports with your advisor as proof of practice.
  2. Focused Improvement: Target 1–2 issues per session (e.g., first reduce “um/like”, then optimise pacing) to avoid overwhelm.
  3. Anxiety Reduction: Leverage Yoodli’s judgment-free environment for repeated practice—confidentiality helps ease public speaking nerves.
