Character Voices

In each of the NPCs there is a description of the "Voice" of the character. It may look something like this:

The notation contains the following attributes:

• Quality: Normal, Nasally, Breathy, Old, Young, Stuttering
• Tempo: Quicker, Normal, Slower, Hesitating
• Percussion: Tapping, Moderate, Sustained
• Directness: Direct, Indirect
• Strength: Strong, Light

If you don't use character voices when playing the NPC, just forget this whole section. Just like everything else in tabletop RPGs, make the character your own. Don't feel like you need to use any of these suggestions.
For more information on how to use these attributes to make each character have a unique voice, I highly recommend the video "How to Create 100 Distinctly Different Voices" by YouTuber "Improve Your Voice".
