AI Course Narration that stays consistent
Generate clear, warm course narration for lessons, tutorials, explainers, and long-form learning content without booking studio time.
How it works
One narrator, every lesson — from raw script to LMS-ready audio in a single studio.
Paste or import your lesson script
Bring in scripts, documents, or chapter text. Unmixr keeps long lessons organized in blocks you can edit and regenerate independently.
Choose your course narrator
Audition voices by language, tone, and teaching style, then lock one narrator in for the entire course.
Direct the delivery
Adjust pacing, pauses, emphasis, and pronunciation so complex terms land clearly and key ideas get the weight they deserve.
Export lesson audio
Download narration for your LMS, video editor, or course platform — one lesson at a time or a whole module at once.
Everything this workflow needs
Built for course creators, educators, coaches, and instructional designers — voice, video, subtitles, transcription, and dubbing in one place.
Long-form narration
Create stable narration for full lessons, chapters, and modules with controlled pacing. Long scripts stay consistent from the first minute to the last.
Natural voice direction
Guide tone, emphasis, and emotion for instructor-style delivery. Make key concepts sound important and transitions sound natural instead of monotone.
Multiple speakers
Build dialogue, role plays, and scenario-based course content with distinct voices per character. Ideal for compliance scenarios, language lessons, and case-study discussions.
Multilingual courses
Generate course narration in 100+ languages for international learners. Keep the same lesson structure and simply switch the narration language.
Pronunciation that sticks
Define how technical terms, names, and acronyms are pronounced once and it applies across the course. No more re-recording a whole lesson over one word.
LMS-ready exports
Download clean audio files ready for your LMS, video editor, or course platform. Update one lesson later without touching the rest of the course.
