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 highly 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 in the Studio preview, copy and paste one of the following phrases into the text entry box to ask your digital person to repeat it:

• After so much effort, seeing the project come to life is amazing.

• You're doing an amazing job!

• It is best to greet elders with a respectful bow.

• I'm not quite finished yet.

• I can't believe you just said that.

, 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.

Empathetic Reaction to User Facial Expression

Digital people can track a user’s face, and detect, analyze and respond to the user's emotional expressions, in real-time.

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.

Empathetic Reaction to User Speech

Digital people can now analyse the emotional content of the words a user says to them, and produce an emotionally appropriate facial performance in reaction to those words, in real-time.

Digital People can express a full range of emotions in reaction to emotional user speech. 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.
