OpenAI's TTS models offer a range of personalities. Choosing the wrong one can ruin your retention.
### The "Authority" Voice
For niches like Finance or History, use a deep, steady male voice. It builds trust and sounds like a documentary narrator.
### The "Relatable" Voice
For lifestyle or story-time niches, use a higher-pitched, more energetic female voice. It sounds like a friend telling a story.
### The "Horror" Voice
Slower pacing and a lower rasp are perfect for scary stories. VidiPrompt lets you customize the "Emotional Tone" of the audio generation.
