By integrating custom instructions, clients can influence the agent's behavior in real-time, ensuring that the conversation aligns more closely with their objectives and requirements. This feature significantly improves user experience by allowing for dynamic and personalized communication.

Cleaner MLLM Turn Handling enhances the ability of the Multi-Layered Language Model (MLLM) to manage conversational turns more effectively. This feature streamlines the process of detecting when a user has finished speaking and when the system should respond, reducing misunderstandings and improving the overall fluidity of interactions. By refining the handling of turn-taking, it allows for a more natural and engaging dialogue experience, ensuring that the system can better interpret user intent and maintain context throughout the conversation.

The unified interruption control is designed to manage how agents respond to interruptions during interactions. It regulates when and how agents can interrupt or be interrupted, ensuring a smooth flow of conversation while maintaining clarity and coherence. By effectively managing agent interruption behavior, it helps balance the dynamics between the agent and the user, allowing for more natural and efficient communication. This control is crucial in environments where timely responses are necessary, enabling agents to maintain engagement without disrupting the user's experience.

In version 2.6, the toolkit introduced new callbacks designed to enhance interaction monitoring. The callbacks onAgentListeningChanged, onAgentThinkingChanged, and onAgentSpeakingChanged allow developers to track the state of the agent more effectively. This enables more responsive and dynamic user experiences by providing real-time updates on the agent's status during conversations. These additions help in creating smoother interactions, as developers can implement actions based on the agent's current state, ultimately improving user engagement and satisfaction.

The 'send a custom instruction' endpoint allows users to provide specific directives or context that can guide the conversation. By injecting custom text instructions, users can tailor interactions to better meet their needs, ensuring the conversation aligns with specific goals or requirements. This functionality enhances the adaptability and responsiveness of the system, allowing for a more personalized and effective communication experience.

Voice Recognition VAD is primarily focused on transcribing spoken language into text rather than detecting turns in a conversation. Turn detection requires distinguishing when one speaker stops and another begins, which is typically handled by methods designed specifically for voice activity detection (VAD). In contrast, Agora VAD, Server VAD, and Semantic VAD are tailored for identifying speech segments, making them suitable for turn detection in multi-party conversations.

The 'interruption' object is designed to manage how and when a user can interrupt the agent during a conversation. It helps define the rules for user interactions, ensuring that interruptions are handled appropriately to maintain a smooth dialogue. By controlling user speech interruption behavior, it allows the agent to respond effectively while minimizing confusion, ensuring that the conversation flows naturally without unnecessary pauses or overlaps in speech. This enhances the overall user experience and improves communication efficiency.

When an agent is in a listening state and a custom instruction is injected, the default action is to inject that instruction into the ongoing process. This means the agent will prioritize the new instruction and integrate it into its current task, allowing for immediate responsiveness to user commands or changes in context. This behavior ensures that the agent remains adaptable and can effectively respond to new information or directives without needing to disrupt its listening state significantly.

The agent name in NCS event payloads plays a crucial role in enhancing visibility across multiple agents operating simultaneously. By identifying each agent uniquely, it allows for better tracking and monitoring of their activities, facilitating easier management and troubleshooting. This clarity is essential in complex environments where multiple agents may interact, ensuring that events can be correlated with specific agents, thus improving overall system observability and operational efficiency.

The 'mllm.turn_detection' object is responsible for managing how the MLLM (Multi-Layered Language Model) module identifies and processes turns in conversation. This involves detecting when the user has finished speaking and when the agent should respond, ensuring smooth interaction flow. Proper turn detection is crucial for maintaining conversational coherence and responsiveness, allowing the agent to effectively engage with user inputs.

The 'greeting_configs.delay_ms' parameter is designed to introduce a specified delay, measured in milliseconds, before the agent delivers the greeting message. This allows for a smoother interaction by giving users a moment to prepare for the incoming message, enhancing the overall user experience. By adjusting this delay, developers can optimize the timing of the greeting to better align with user expectations and improve engagement.

In version 2.6, the field "advanced_features.enable_mllm" was deprecated, indicating that it is no longer recommended for use and may be removed in future versions. Deprecation typically occurs when a feature is outdated or replaced by a better alternative, prompting developers to transition to newer methods or configurations. This helps streamline the software and encourages best practices, ensuring that users adopt more efficient or secure options while maintaining compatibility with the latest updates.

The 'interruption.enable' parameter determines if an agent can be interrupted during its interaction. When enabled, users can interrupt the agent's speech or actions, allowing for a more dynamic and responsive conversation. This feature is particularly useful in scenarios where immediate user input is necessary or when the agent's response may not be relevant to the user's needs. By controlling interruptions, the parameter enhances the overall user experience and ensures that interactions remain fluid and engaging.

The 'interruptable' parameter typically indicates whether an operation can be interrupted. In many systems and frameworks, the default value is set to true, allowing processes to be halted if necessary. This design choice enhances flexibility and responsiveness, enabling better resource management and user control. By defaulting to true, it ensures that tasks can be interrupted when needed, promoting efficient operation in dynamic environments.

The main focus of the conversational AI engine v2.6 release is to improve how agents manage conversations and respond to users. This enhancement allows for more natural interactions, better understanding of context, and improved handling of user queries. By focusing on agent control, the update aims to create a more seamless and efficient user experience, ensuring that conversations are not only coherent but also tailored to individual needs. This is crucial for maintaining engagement and satisfaction in AI-driven communication.

The release date of conversational AI engine v2.6 is set for April 22, 2026, as this date aligns with the planned development schedule and testing phases established by the development team.
