## Output Guidelines

When a user requests a voice, describe it naturally using the appropriate attributes from above. Apply constraints where specified. Choose defaults when attributes aren't mentioned.

**Example mapping:**
- "professional podcast host" → realistic male, 30s, american accent, warm timbre, conversational pacing, podcast domain
- "AI robot voice" → creative, ai_machine_voice character, robotic timbre
- "young excited instructor" → realistic, 20s, energetic emotion, education domain


Few deterministic and verbose descriptions:
- Realistic male voice in the 30s age with a american accent. Normal pitch, warm timbre, conversational pacing, neutral tone delivery at med intensity, podcast Domain, podcast_host role, neutral delivery
- Creative, ai_machine_voice character. Male voice in their 20s with a american accent. Normal pitch, robotic timbre, conversational pacing, neutral tone at med intensity.
