Soul App has launched a groundbreaking full-duplex voice model, revolutionizing how artificial intelligence interacts in social scenarios. Announced on July 10, 2025, in Shanghai, this upgraded model enhances AI’s ability to manage conversation timing autonomously, enabling a more natural and immersive communication experience.
The new model moves beyond traditional voice activity detection systems and eliminates the typical delays associated with human-AI interactions. By allowing AI to independently decide when to speak, the model facilitates simultaneous conversations, where users and AI can interrupt each other, contribute to discussions, and even break silences proactively. This development aims to create a dialogue environment that mirrors real-world interactions.
Transforming Human-AI Conversations
Historically, conversations with AI have adhered to a question-and-answer format, often interrupted by latency issues. The original full-duplex model introduced by Soul in 2024 featured advanced capabilities such as ultra-low latency and hyper-realistic voice expression. With this latest upgrade, the AI can now interpret complex auditory inputs while expressing a wider range of emotions.
The model enhances interaction through several key features:
1. **Autonomous Decision-Making:** The AI can predict when to respond, listen actively, or interrupt, creating a fluid conversation dynamic. This autonomy fosters a more natural dialogue that allows for debates, discussions, and collaborative exchanges.
2. **Emotional and Colloquial Expression:** The upgraded model incorporates vocal nuances like laughter, stammering, and everyday speech patterns. This approach aims to make interactions feel less robotic and more akin to human conversation. The AI’s ability to express emotions in a nuanced way significantly enhances user engagement.
3. **Contextual Awareness:** By integrating elements such as time, environment, and conversational context, the AI can respond in a manner that feels relevant and timely. This capability enables the development of rich narratives and emotional exchanges.
Expanding Social Interaction Capabilities
Looking ahead, Soul App plans to implement this model in both one-on-one and group scenarios. The AI will be able to actively participate in group conversations, recognizing optimal moments to contribute and facilitating topic extensions within social dynamics. This development aims to foster deeper connections among users.
Tao Ming, Chief Technology Officer of Soul App, expressed the company’s vision: “Social interaction is an exchange of emotional and informational value. Soul is committed to leveraging innovative technology to deliver smarter and higher-quality interactive experiences that alleviate loneliness.”
As AI continues to reshape social interactions, Soul App’s advancements reflect a growing demand for human-like behavior in AI. According to the 2025 Gen Z AI Usage Report, approximately 60% of users desire AI that behaves more like a human companion. This new full-duplex model is expected to significantly enhance AI’s role in socializing, ushering in a new era of human-AI interaction.
Soul App remains dedicated to building a social ecosystem where both “AI Beings” and “Human Beings” coexist, continuously investing in technology that enriches emotional support systems and enhances individual well-being.
