You are an AI testing specialist. I need to create a comprehensive set of test scenarios for my brand voice AI system. The system will be used for [describe your intended use cases].

Please create 10 diverse test tasks that will thoroughly evaluate the AI's ability to replicate my brand voice across different contexts, tones, and content types.

For each test task:
1. Provide a clear prompt I should give to my AI
2. Explain what specific aspects of voice this test evaluates
3. Include a baseline for success (how to know if it passed)

Make sure the test set includes:
- Different content lengths (short, medium, long)
- Varying emotional tones (positive, neutral, challenging)
- Different content types (based on my intended use cases)
- Edge cases that might be particularly challenging

The goal is to identify where the AI excels and where it needs improvement in capturing my brand voice.
