Best Practices
Tips for getting the best results from DemoVoice.
Recording Tips
Speak Naturally
Record your demo as if you were explaining it to a colleague. Natural pacing and pauses help DemoVoice produce better results. Don't worry about your voice — it will be replaced.
Use Clear Enunciation
Even though the audio will be replaced, clear speech helps Whisper transcribe accurately. Avoid mumbling or speaking too quickly.
Allow Natural Pauses
Leave brief pauses between sentences and when transitioning between topics. This gives DemoVoice clear segment boundaries to work with.
Minimize Background Noise
While DemoVoice replaces your audio, Whisper needs to hear your original voice. Record in a quiet environment for best transcription accuracy.
Configuration Tips
Start with Defaults
The default timing controls work well for most videos. Only adjust stretch/compress values if you notice timing issues in your output.
Test Voices First
Render a short clip with each voice before committing to a full video library. Different voices suit different content types.
Build a Comprehensive Glossary
Before your first render, add all product names, technical terms, and acronyms to your glossary. This prevents mispronunciations from propagating.
Use Profiles for Different Content
Create separate profiles for tutorials (slower, clearer), marketing (energetic), and technical deep-dives (neutral, precise).
Workflow Tips
Always Inspect First
Run demovoice inspect before rendering to verify transcription accuracy. Fix any issues in the source video rather than working around bad transcription.
Version Your Config
Commit your .demovoice/ directory to version control. This ensures all team members use consistent settings and lets you track changes over time.
Batch Similar Videos
When processing multiple videos, group them by type and use the same profile. This ensures consistency across your video library.
Review Before Publishing
Always watch the rendered video before publishing. AI-generated speech occasionally has artifacts that need a re-render with adjusted settings.
Team Workflow
Standardize Early
Before your team starts creating demos, agree on a single voice, build a shared glossary, and document your recording guidelines. Consistency is easier to maintain than to retrofit.
