Recipient design and the relevance of empathetic conversations

Designers and programmers often follow a traditional approach in creating interfaces, both conversational and visual, where users interact with predefined steps to achieve specific goals. This approach results in a linear and guided user experience.

Recipient design, based on sociolinguistic principles, offers an alternative method that focuses on adapting interactions in real-time based on implicit cues like timing, content, and tone. It creates more human and engaging conversational interfaces using session data and cue-based recommendations to adjust conversation flow dynamically. This approach also includes adjusting speech tone and using AI to match the user's emotional state for personalized interactions, recognizing the importance of social context for deeper understanding and adaptation to users' changing preferences and contexts.

The building blocks of an AI-based conversational empathetic system

User interface

User interfaces in conversational AI systems are crucial, bridging users with technology through text or voice. They must be intuitive and user-friendly, whether through responsive text interfaces or more immersive AI-powered Digital Humans, to cater to diverse user needs and environments.


Speech-to-text technology is essential in conversational AI, converting human speech into text with nuanced understanding. It enables natural user interaction across various applications and is evolving with multilingual capabilities, driving advancements in AI and natural language processing.

Emotion recognition

Emotion recognition in conversational AI involves analyzing verbal and non-verbal cues to understand human emotions accurately. This requires integrating text, voice, and visual data, considering cultural and individual variations. Continuous adaptation and learning are essential for these systems to keep up with evolving emotional expressions.

Large Language Models

Large Language Models (LLMs) enhance conversational AI by understanding a wide range of tasks and contexts, often requiring prompt engineering for complex queries. Their effectiveness in conversational systems depends on factors like data quality, privacy, and scalability, ensuring efficient and accurate user interactions.

Text-to-speech & voice cloning

Advanced text-to-speech technologies in conversational systems provide realistic, varied voices, enhancing user experience. Developments like voice cloning offer personalisation but raise ethical concerns, necessitating strict guidelines and regulations for responsible use.
