iFLYTEK Announces Patent for Accent and Style Control in Human-Computer Interaction
Chinese artificial intelligence company iFLYTEK has announced a newly published patent for a method and device to control accent and style in human-computer interaction dialogue systems. The patent, discovered through Tianyancha's intellectual property information, falls within the domain of intelligent dialogue and speech synthesis technology. The described method involves receiving user dialogue requests and determining if they include specific demands for accent or style control. Based on this assessment, the system identifies and stores corresponding accent and style values. These values are then updated or inherited across multiple turns of the conversation, taking into account the current dialogue stage and control requirements. Following this, the system generates a text-based response aligned with the user's request intent. Finally, using the determined accent and style values for the current turn, the system invokes the appropriate Text-to-Speech (TTS) synthesis model to convert the text response into target speech for the user. This invention aims to address limitations in existing technologies, such as weak dynamic control over accent and style, a lack of state inheritance in multi-turn dialogues, insufficient scenario adaptability, and high system expansion costs.
This patent filing by iFLYTEK highlights a strategic focus on enhancing the naturalness and user-centricity of AI-powered voice interfaces. By enabling granular control over accent and conversational style, the technology aims to improve user experience and broaden the applicability of voice assistants across diverse linguistic and cultural contexts. The ability to dynamically adjust these parameters and maintain state across multiple turns suggests a move towards more sophisticated, context-aware dialogue systems. This development is particularly relevant in the context of an increasingly globalized digital landscape where personalized and adaptable human-computer interaction is becoming a key differentiator for AI service providers. The system's design appears to address existing technical challenges, potentially paving the way for more nuanced and effective voice-based communication tools.
