YouTube-specific tips:
- Hook your viewers: Start scripts with a comma after the opening phrase (e.g., "In this video, we'll explore...") — the pause adds emphasis and keeps viewers watching
- Consistent branding: Pick one voice as your "channel voice" and use it consistently. Viewers associate voice identity with brand recognition
- Script formatting for TTS: Write like you speak, not like you write. Use contractions ("we'll" not "we will"), short sentences, and conversational tone for natural-sounding AI narration
- Audio levels: WAV files from OfflineTTS are at consistent levels. In your video editor, normalize to -14 LUFS for YouTube to match platform standards
- Multi-language content: Generate voice-overs in multiple languages for the same video. Export separate audio tracks and let viewers choose
Our top voices for YouTube: Heart (warm, educational), Bella (energetic, vlogs), Michael (professional, reviews).

Turn a YouTube Script into Timed Narration in Small Sections
This page creates voice-over audio, not a finished YouTube video. It does not edit footage, add captions, mix music, publish a channel, or determine monetization eligibility. Mark the script by scene, visual cue, and target duration, then synthesize short sections that can be aligned on a video editor timeline instead of generating one difficult-to-revise track.
Test the opening hook, channel name, sponsor terms, product names, numbers, and calls to action in the selected voice. Estimate timing from an actual sample because punctuation and speed settings do not produce an exact runtime. Keep the approved script with the engine, language, voice ID, and speed used for each exported segment.
Review YouTube Rights, Pronunciation, and Platform Claims
Listen to the voice-over against the final visual edit, not only as an isolated audio file. Check pronunciation, pacing around cuts, music masking, and every segment join. Add captions from the approved script and verify their timing separately. OfflineTTS is not affiliated with YouTube and cannot promise reach, revenue, copyright clearance, or policy compliance.
Use only scripts and assets you have permission to publish, and do not imply that a synthetic voice is a real person or sponsor. Text handling depends on engine and language; several non-English Kokoro routes require phonemization requests. Choose a local-processing route when confidentiality rules require it and review the Privacy page before entering embargoed material.
