Step-by-Step Guide
How FluxNote Generates Voiceovers
FluxNote uses AI text-to-speech technology to convert your script into a spoken narration. The system produces natural-sounding speech with appropriate pacing and intonation, generating audio that sounds like a professional voice actor reading your script.
Available Voices and Selection
FluxNote offers multiple AI voices with different tones, genders, and accents. Creators select a voice before generation to ensure the narration matches their channel's identity. Premium voices with more expressive delivery are available on paid plans.
Word-Level Caption Sync
FluxNote's voiceover system produces word-level timestamps alongside the audio — these timestamps drive the animated caption display. Each word appears on screen at the exact moment it is spoken, creating precise karaoke-style caption synchronization.
Voiceover and Music Balance
FluxNote automatically mixes background music at a volume level that supports the voiceover without competing with it. No manual audio balancing is needed — the voiceover is always the dominant audio element in the exported video.
Pro Tips
- Avoid overly long sentences in your script — AI voices perform better with short, punchy sentence structures.
- Use punctuation to control pacing: commas and periods create natural pauses that make the voiceover sound more human.
- Preview multiple voices on a short script excerpt before committing — tonal fit matters for audience retention.
- Numbers and abbreviations may be read differently by AI voices — spell out numbers and acronyms if pronunciation is critical.
- Keep scripts conversational — first and second person language sounds most natural in AI narration.
