### Step-by-Step Solution:

1. **Understand Voice Types**: The question presents four types of voices: baby girl, baby boy, man, and woman.

- **Baby Boy**: Similar to baby girl, but may have slightly lower pitch as they grow.
- **Woman**: Typically has a higher pitch than men but lower than children.
- **Man**: Usually has the lowest pitch among the four due to larger vocal cords and deeper voice.
