Raisound VoiceGPT, is a private deployed large model for different industries, which based on voice related AI+ capabilities. It consists large-scale acoustic models, large language models, acoustic event processing models, and professional knowledge bases. Based on the core framework of “cloud + chip + self-evolution,” VoiceGPT utilizes multimodal sound interactions to achieve the fifth-generation human-computer interaction which also known as natural user interface(NUI). We hope NUI will provide a new generation of interfaces for various professional information systems in the future.
