This section describes the options available in Digital DNA studio that allow you to control and fine-tune the behavior of your Digital Person.

Behavior Adjustments

Behavior adjustments using tags enable you to add a limited set of facial expressions and gestures to selected words, phrases, and sentences in your digital person's speech. When Real-Time Gesturing is unavailable (due to language choice or Human OS version) Behavior Tags are the primary tool for adding appropriate head and neck gesturing and emotional expressions to your digital person's behavior.

When Real-Time gesturing is available, Behavior Tags can be used to adjust the autonomous behavior of the digital person:

• You can use Behavior Tags to override Real-Time Gesturing for specific sentences or words spoken by your digital person.

• You can use the behavior tags to override the autonomous behavior with something more appropriate to your use case. For example, you might want to add brand and product-related words to Smiling Gesture (Word-Based).

• You can also use Neutral Long (Sentence-Based) and Neutral Short (Word-Based) to define sentences and words that will temporarily deactivate the real-time gesturing entirely.

Other Behavioural Settings

Enable users to verbally interrupt the Digital Person

When enabled, the digital assistant will automatically yield the conversation floor to the user upon detecting their speech. The digital person will also refrain from interrupting or speaking over the user. This interruption feature is compatible with Generative Conversation Base and other LLM-based Base Conversations. However, it may not function with other Base Conversations, such as NLP or node-based dialogue systems.

Boost Expressiveness with additional Iconic Gestures toggle

When enabled, the digital person will automatically insert iconic gestures into the conversation. Iconic gestures are context specific gestures which are tied to the meaning of a sentence, rather than a specific word. For example, a peace sign gesture, a bow, a thumbs up gesture. Iconic gestures were previously only possible if they were manually added to conversations using Gesture Markup.

To see some of these gestures in action, try asking your digital person to recommend their top five books with the word heart in the title. Be sure to click update preview after enabling this toggle to see these gestures.

My Digital Person should greet me at start

This option makes your Digital Person greet users as it starts up to provide them with a verbal cue that the interaction has commenced. This setting is enabled by default. If this option is turned off the Digital Person will wait for the user to initiate the conversation.

End session after x minutes of inactivity

This option makes your Digital Person automatically end the conversation session with the user, after a specified period of inactivity from the user side, e.g. after 5 minutes. This setting is enabled by default.

React to negative facial expressions toggle

When enabled, this toggle allows the digital person to react to both positive and negative expressions on users' faces. When disabled, the digital person will only react to positive facial expressions. The toggle is enabled by default.

When using Real-Time Gesturing and Behavior Styles, each behavior style has its own, behavior-appropriate reactive style.

React to negative speech toggle

This toggle allows the digital person to react to both positive and negative user speech. When disabled, the digital person will only react to positive user speech. The toggle is enabled by default.
