| ## 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. |
