Narration Room is a free Mac and iPhone app that turns text into editable multi-voice audio scripts. It runs entirely on-device, requires no account or subscription, and provides 40+ Apple voices you can assign to different speaking parts inside a visual timeline.
Import a PDF, Word document, Markdown file, or paste text directly. You can also dictate a script. The app wraps your source in a template (study guide, briefing, product walkthrough, etc), then lets you cast voices, adjust pitch and emphasis, add breaks, and preview the full narration before you export it as WAV, MP3, AAC, plain text, SSML, or SRT subtitles.
Features
- Imports PDF, Word, and Markdown files into Mac narration projects.
- Starts from pasted text, clipboard content, dictation, or a blank draft.
- Uses templates for product onboarding, study guides, briefings, and other structured scripts.
- Divides longer narration projects into named modules for easier editing.
- Converts source material into narration, summaries, or multi-speaker dialogue scripts.
- Assigns on-device narrator voices by speaker, tone, and language.
- Adjusts pitch, emphasis, and breaks before audio generation.
- Previews narration on a visual timeline and regenerates an individual cue after revisions.
- Exports WAV, MP3, and AAC audio files.
- Exports plain text, SSML, and SRT subtitle files.
- Stores iPhone narrations and transcripts in a local library with optional iCloud sync.
Use Cases
- Turn lecture notes or textbook chapters into audio study guides with separate voices for questions and answers.
- Generate multi-voice podcast segments or intros without recording live speakers.
- Produce private audiobook drafts from manuscript files before you enter a studio.
- Dictate a rough script on iPhone, assign Apple voices, and hear it back to refine pacing and phrasing.
- Create narrated product walkthroughs where each step uses a distinct voice cue.
- Build a library of spoken briefings that stays on your device and plays offline.
How to Use Narration Room
1. Install Narration Room from the Mac App Store or iPhone App Store. Make sure the initial voice or model download finishes before starting your first project.
2. Start with a blank project or choose a template. Product onboarding, study guides, and briefings benefit from templates because each section becomes a separate editable module.
3. Paste text, import a document, or dictate source material. Remove navigation text, repeated headings, citations, URLs, and table fragments before turning the draft into speech.
4. Review the source in the editor. Split long paragraphs where the speaker, topic, pace, or tone changes.
5. Select the narration direction. Keep the original wording for direct narration, create a shorter spoken summary, or build a dialogue between several speakers.
6. Assign voices to each narrator or speaker. Adjust pitch, emphasis, and breaks where the script needs stronger pacing or clearer transitions.
7. Preview the project on the visual timeline. Edit one cue and regenerate that cue when a line needs revision. Cue boundaries reduce the scope of later rewrites.
8. Export the final audio as WAV, MP3, or AAC. Export SRT in the same pass when the narration moves into a video editor. Export SSML when your next audio tool needs speech markup.
