AI Technical Summary

Technical Problem

Existing multimodal depression detection methods neglect acoustic rhythm information, fail to effectively isolate non-pathological noise, ignore the alignment relationship between speech rhythm and text content, resulting in inaccurate rhythm feature extraction, and fail to dynamically adjust fusion weights during the feature fusion stage.

Method used

By extracting stable rhythm features and removing non-pathological acoustic interference, semantic anchoring technology and soft dynamic time warping framework are used for cross-modal monotonic time alignment. Multi-scale convolution and sliding window techniques are combined to extract pathological speech rate evolution features. A multi-modal adaptive fusion architecture is constructed to dynamically adjust the expression weights of rhythm abnormal evolution data, and finally, depression risk stratification prediction is performed.

Benefits of technology

It significantly improves the accuracy and clinical robustness of depression identification, enhances the accuracy of pathological rhythm feature extraction, strengthens the ability to perceive the dynamic evolution of speech rhythm in users with depression, and optimizes auxiliary diagnostic results.

Abstract

本发明公开了人工智能辅助医疗诊断技术领域的一种基于声学节奏异常演化嵌入的多模态抑郁风险监测方法,包括获取用户访谈音频和所述访谈音频的转录文本,采用预训练编码器提取所述访谈音频的初始声学特征序列和语境化语义特征序列;基于语义锚定技术,采用软动态时间规整框架建立跨模态单调时间对齐约束。本发明通过动态强化病理性节奏演化特征在复杂交互语境下的特征表达权重,将聚合融合后的多模态特征映射至决策层对抑郁风险进行分层预测,同时通过将提取后的病理节奏演化特征与上下文语义进行动态融合,能够在声学特征的节奏异常演化方向上嵌入模型建模,从而显著提升抑郁症识别的准确率和临床稳健性。
