Prepare the script for speech
Use short paragraphs and natural punctuation. Replace long written sentences with spoken phrasing, especially when the story contains names, dates or emotional turns. Read the script aloud before generation to find places where breath or emphasis is needed.
Avoid excessive ellipses and repeated punctuation. They may create unpredictable pauses rather than natural emotion.
Start near normal speed
Begin around a natural speaking pace and adjust in small steps. Emotional scenes often need slightly more space, while an introduction or recap can be a little faster. Very slow speed can expose synthetic transitions between words.
Test the same paragraph at two nearby speeds instead of changing several settings at once. This makes the difference easier to judge.
Use pitch changes conservatively
A small pitch adjustment can make a voice feel warmer or brighter, but a large shift may reduce clarity and make the voice sound processed. Choose the voice character first, then use pitch only for fine tuning.
Male and female voices may respond differently to the same pitch setting, so keep separate presets for each selected voice.
Apply Humanizer and dramatic pauses with purpose
Balanced Humanizer is a practical starting point for normal narration. Use stronger dramatic pauses only before a reveal, decision or emotional line. If every sentence receives the same pause, the delivery becomes predictable and robotic.
Check whether punctuation already creates enough space. A good script may need only light Humanizer processing.
Master for the final mix
Set voice level while background music is playing. Loudness normalisation can create a consistent target, but it cannot repair clipped generation or poor pronunciation. Regenerate incorrect lines before mastering.
Listen on headphones and a phone speaker. The final narration should remain clear without sounding harsh, especially on consonants and high-frequency sounds.
Frequently asked questions
Which Humanizer level should I start with?
Balanced is a useful starting point. Use Light for already well-punctuated scripts and stronger settings only when the story needs them.
Should emotional narration always be slower?
Not always. Slow only the lines that need space and keep the overall rhythm moving.
Can mastering fix wrong pronunciation?
No. Correct the script spelling or voice choice and regenerate the line before mastering.
