Lectures & Audio Narration

Reading Lectures

Each lecture contains expert-designed content organised into clear paragraphs. Lectures include:

• Learning Objectives -- What you'll learn (shown at the top)
• Main Content -- The lecture text with key concepts explained
• Glossary -- Key terms and definitions
• Summary -- AI-generated summary of key points

Audio Narration

Most lectures include professional audio narration. Use the audio player at the top of the lecture to:

• Play/Pause -- Start or stop the narration
• Seek -- Jump to any point in the audio
• Speed Control -- Adjust playback speed (0.75x to 2x)
• Volume -- Adjust or mute the audio

The lecture text highlights the current paragraph as the audio plays, so you can read along.
