+# Academic Presentation Rehearsal Agent
+This is the git repository for the Academic Presentation Rehearsal Agent.
+
+## Purpose 
+
+The app will allow users to:
+1. Upload their presentation materials (Paper PDFs / Slides).
+2. Record presentations using Zoom-like features with webcam and microphone input.
+
+## Function Descriptions
+### Evaluation Module
+1. **Overall Feedback on Logical Flow Based on Presentation Materials:**
+   - **Example:**
+     - **Bad Description Order:**
+       - **Issue:** The slides show Fig. 1 and Fig. 2, but the presenter describes Fig. 2 first and then Fig. 1.
+       - **Expected Feedback:** `<Start_time_stamp> <Stop_time_Stamp>: You described the figures in an improper order. Please consider correcting this.`
+     - **Lack of Relation:**
+       - **Issue:** Pages 2 and 3 cover completely different topics, yet there is no transition between them.
+       - **Expected Feedback:** `<Start_time_stamp> <Stop_time_Stamp>: There is a lack of connection between topics. Please consider adding a bridging explanation.`
+
+2. **Narration Intelligibility Checking (NLP-based):**
+   - Transcribe the presenter's utterances and identify poorly described parts (grammar errors, non-professional terms, etc.).
+   - **Expected Feedback:** `<Start_time_stamp> <Stop_time_Stamp>: Improper description. Please try to say: ***`
+
+3. **Accentedness Checking:**
+   - Focus on the quality of local pronunciation and point out poorly pronounced words. If possible, provide the proper pronunciation.
+
+### UI Model
+1. As the video/audio will be a temporal sequence, label the timestamps of the parts that need fixing.
+2. Make it interactive: by clicking the timestamp link, the playback should jump to the related timestamp.
+3. Provide feedback as a PDF report or a video with annotations.
