This predefined persona is designed to act as a friendly virtual doctor, offering quick answers to user health inquiries. It includes:

Persona Identity: A helpful and knowledgeable “Health Care” assistant who can provide medicines to cure various diseases.
Full Pipeline Mode: Enables the full Tavus conversational pipeline, including Perception, STT, LLM, and TTS.
System Prompt: Instructs the replica to behave as a trusted medical advisor. It ensures the persona understands its role in responding to disease-related questions and calling the appropriate tool to provide answers.
Context: Clarifies expected user inputs (e.g., “What is the cure to X?”) and defines how the replica should interpret and respond—by acknowledging the illness and triggering the get_cures function with the specified disease name.
Model Layers:
- LLM Configuration: Uses the tavus-llama model with speculative inference. Includes the get_cures tool, which accepts a single string parameter (disease) and limits AI behavior to relevant function calls only when disease-related queries are detected.
- TTS Layer: Employs the cartesia voice engine with emotion control.
- STT Layer: Uses tavus-advanced engine with smart turn detection for seamless real-time conversations.

This predefined persona acts as a virtual skin care specialist. It offers users professional yet warm advice for treating skin-related concerns and leverages both conversational understanding and visual perception. It includes:

Persona Identity: A friendly and knowledgeable “Personal Skin Doctor” who helps users find cures for skin conditions.
Full Pipeline Mode: Enables the full Tavus conversational pipeline, including Perception, STT, LLM, and TTS.
System Prompt: Directs the persona to behave like a helpful skin doctor, answering cure-related questions clearly and empathetically.
Context: Guides the persona to respond when users ask questions like “What is the cure to X” or “What is the solution to X.” The AI is instructed to extract the disease name and call the get_skin_cures tool to fetch a relevant response.
Model Layers
- LLM Configuration: Uses the tavus-llama model with speculative inference. Includes the get_skin_cures function, which takes a disease input to provide specific treatment guidance.
- Perception Configuration:
  
  Integrates the raven-0 model to visually assess the user’s face. It runs ambient queries like:
  - “Does the user have acne on their face?”
  - “Does the user appear distressed or uncomfortable?”
  If acne is detected, the persona is instructed to use the acne_detected tool, which reports visual findings using a boolean have_acne parameter.
- TTS Layer: Employs the cartesia voice engine with emotion control.
- STT Layer: Uses tavus-advanced engine with smart turn detection for seamless real-time conversations.
