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).
