From Lesson Script to Narrated Audio
Introduction to Trigonometry
Lesson 1
Today we're going to learn one of the most useful tools in all of mathematics: trigonometry. Don't let the name intimidate you. At its core, trigonometry is just the study of triangles, specifically right triangles. And once you understand three simple ratios, you can solve problems that range from measuring the height of a building to navigating a ship across the ocean. Let's start with a right triangle—that's any triangle with one 90-degree angle. The longest side opposite that right angle is called the hypotenuse. The other two sides are named relative to whichever of the remaining angles you're focused on. We'll call that angle theta.
Core Capabilities
Everything You Need to Narrate a Course
When your content changes, your narration changes with it. Export audio ready for your LMS, video editor, or slide deck in any language.
From Script to Narrated Lesson
Paste your lesson content or import from a document. Choose a narrator voice, adjust pacing, and export audio files for each lesson. One tool handles your entire course catalog.
Update Content Without Re-Recording
Curriculum changes are inevitable. When a lesson needs updating, edit the script and regenerate just the affected sections. No narrator to re-book, no studio to schedule. Your narration stays current with your content.
Consistent, Clear Voices for Every Lesson
Students hear the same reliable narrator across your entire curriculum. The AI voice never gets tired, never changes tone between recording sessions, and delivers the same clarity whether it is lesson one or lesson fifty.
