The Three Core Controls Explained
Speed (Rate) — Controls Words Per Minute
Speed controls how fast the voice speaks. Default is 1.0x. Below 1.0x slows it down, above speeds it up.
| Speed | Effect | Best For |
|---|---|---|
| 0.75x – 0.85x | Very slow, deliberate | Meditation, audiobooks, kids content |
| 0.85x – 0.95x | Measured, serious | Documentary, serious topics, Hindi educational |
| 0.95x – 1.05x | Natural conversational | Tutorials, explainer videos, general use |
| 1.1x – 1.2x | Energetic, engaging | Social media, gaming, news summaries |
| 1.25x+ | Fast, punchy | Short-form content, quick tips |
Pitch — Controls Voice Frequency (High or Low)
Pitch controls how high or low the voice sounds. Negative = deeper, Positive = higher. Stay within -5 to +5 for professional results.
- -5 to -3: Deep, bass resonance — documentary, authority content
- -2 to -1: Slightly lower — news, finance, serious topics
- 0 (Neutral): Voice's natural character — best for most content
- +1 to +3: Brighter, approachable — educational, friendly content
- +4 to +6: High energy — youth content, social media
- Beyond ±7: Cartoon effect — comedy only
Volume — Keep at 100% Always
Always keep volume at 100% and adjust loudness in your video editor. Going below 70% introduces noise floor issues. Use Audacity's Loudness Normalisation to -14 LUFS for YouTube.

💡 Pro Tip: Always generate a 30-second test clip before committing to a full script. Change one setting at a time and listen to the difference. Making multiple changes at once makes it impossible to know what improved the audio.
✅ Golden Rule: When in doubt — Speed 1.0x, Pitch 0, Style "General". Then adjust one setting at a time from that clean baseline.
