Personas are the ‘character’ or ‘AI agent personality’ and contain all of the settings and configuration for that character or agent. For example, you can create a persona for ‘Loving girlfriend’ or ‘Dr. Ava’. Personas are where you can customize the layers for CVI as well as prompt the LLM to give it a personality and context. A persona consists of:
  • Character Name - This is the name that is shown when an avatar using your Persona joins the call.
  • Character Prompt - This is the character prompt that the LLM uses for its instructions. Use this to include instructions on who the persona is and how you want them to behave.
  • Conversation Context - This is the knowledge-base that will be fed into the LLM model for your persona. You can dump documentation, background, writing etc here.
  • ​Frist message​​ - The first message spoken.​​​
  • Error Message (for LLM & TTS/ASR errors)​​ - Plays a backup script when errors occur.​​
  • ​​LLM & TTS/ASR- ​​Use the platform’s default configuration or integrate third-party APIs.
  • Avatar - Optionally you can specify a default avatar you’d like this persona to use. You can always override during conversation creation time to use a different avatar.

How to Create a Character

​
Via the UI

Dashboard has limited options You cannot currently customize all layers via the dashboard UI Navigate to the Duix.com Platform . On the sidebar click on Conversation Library. Finally, click Create Conversation.
Limits for character prompt or knowledge are different depending on the LLM model being utilized.
A good character prompt and context base is key to have your persona act the way you want it to during a conversation. Here are some things to keep in mind:

​
Character Prompt

The character prompt should inform who the persona is and how they should act. These are the persona’s ‘instructions’. For the character prompt:
  • Assume a character
  • Provide clear instructions
  • Keep it concise
  • Keep knowledge in the knowledge prompt
Remember that CVI has vision capabilities, you can use this as well to prompt behavior and responses. Here’s an example of a simple, good character prompt:
You are Tim, an avatar created using DUIX. You are taking on the personality of Hassaan Raza, the CEO and Co-Founder of DUIX. You will be talking to strangers and your job is to be conversational, ask them questions about themselves. Be witty and charming. If you don’t know something, just say you’ll get back to them on that.

​
Context / Knowledge-base

The context is the persona’s ‘knowledge base’. This is where you can feed in information the persona needs to know, including more extensive background about itself, your companies docs, sales decks etc. Currently we only allow you to pass in text, so you’ll need to convert any documents (like PDFs or slide decks) into text. For the knowledge/context:
  • Make sure not to accidentally override the character prompt with instructions that may be hidden in your context/knowledge
  • Keep the knowledge-base clean and filtered
  • You do not need to include participant or conversation/specific context, you can pass that in during conversation creation time
The Duix orchestration system will automatically attempt to optimize and align with the selected LLM to optimize your persona for natural conversation.
