Research on the application of virtual digital human voice interaction based on Spark large model

In the context of artificial intelligence, virtual digital human technology has shown wide application potential in many fields due to its ability to simulate various characteristics of human beings. As the most intuitive way of communication, voice interaction, traditionally limited by recognition ability, cannot meet the needs of complex interaction. This paper uses the fantasy engine as the development environment, combines the Rider compiler to develop real-time voice interaction programs, and integrates the Spark model to achieve excellent interaction performance an visual effects. Through experiments, the effectiveness of the system in improving interaction quality and optimizing user experience is verified, and its cross domain application potential is discussed.
