How personas run
- A Digital Human runs once as each persona it lists, and once as the baseline, its own settings, when it has none.
- A persona replaces only the caller fields it sets. The intent, success criteria and everything else come from the Digital Human, so every call still tests the same goal.
- Editing a persona changes every Digital Human that runs as it, from the next run on. Past conversations keep how they ran.
- Each conversation records the persona it ran as.
Fields
There is no emotion setting. To make the caller angry, rushed or confused, write that attitude into Personality Description.
Behavior
Use behavior settings to test whether your agent copes with harder callers, for example a fast talker on a bad connection.- Patience (seconds) is how long the caller waits before it replies.
- No Response Timeout (seconds) must be 15 seconds or more.
- Creativity from 0.0 to 0.3 makes the caller say much the same thing on each run.
- Speaks First: the caller speaks first unless you change it. Some voice platform connections start with the agent.
Scripted responses
A scripted response makes a reply the same on each run. Each one pairs a line the agent says with the caller’s reply: words, keypad tones, silence, or an audio clip. Scripted responses live on the Digital Human, so they apply whichever persona it runs as. The Persona API acceptsscripted_responses too, but runs use the Digital Human’s.
- Under When the agent says, write a line the agent says, for example “Can I have your account number?”. A description of agent behavior never matches.
- Matching on context also catches lines with the same meaning in other words.
- If How scripted responses fire runs them in order, each one fires once, in list order.
The Default persona
Each workspace has a Default persona, a plain caller with an American voice and no background noise. A plan uses it when you do not pick a persona. You can edit the Default persona, but not delete it.Add personas
Open Digital Humans, go to the Personas tab, and click New persona, or upload a personas CSV. A simulation plan also picks personas for you and saves them here when you run. Deleting a persona removes it from every Digital Human that runs as it.Write a good persona
- Describe the person, never the task. “Cancel my plan” belongs in the Digital Human.
- Make each persona differ from the others in one way that matters to your agent, such as a strong accent, a noisy line, or an impatient caller.
- Keep personas few and reuse them. Each persona on a Digital Human is one more call per run.
