6. Signature Design Concept

Interactive "Speaking Coach" Landing Page

The homepage will feature a dynamic AI-powered speaking coach as its centerpiece. Users will see a 3D animated microphone icon that pulses gently, inviting them to "Start Speaking."

• Interaction: When users click the microphone, the page transitions into a real-time voice analysis interface.
• Animations: A wave-like animation visualizes the user's voice input, with colors shifting based on pronunciation accuracy (e.g., green for correct, red for improvement needed).
• Feedback: Instant suggestions appear as floating text bubbles, guiding users on fluency and pronunciation.
• Background: A subtle gradient animation (from #F4F8FB to #FF6F61) creates a calming yet engaging atmosphere.

This bold design will make the platform instantly memorable and emphasize its focus on dynamic, real-time learning.

7. Non-Functional Requirements

• Performance: The system must support up to 10,000 concurrent users with minimal latency.
• Scalability: Cloud-based architecture to handle user growth seamlessly.
