摘要
阅读绘本器发音准确性是提升阅读绘本质量的关键,提出基于语音交互的阅读绘本器发音准确性检测模型构建方法。采用语音传感器实现对阅读绘本器的语音信息检测,建立阅读绘本器发音语音信号模型,采用数字化滤波检测方法进行阅读绘本器发音语音特征检测和谱分析,采用语音交互和语音增强方法,建立阅读绘本器发音语音特征检测和噪声分离模型,在给定虚警概率下建立最优阅读绘本器发音语音信号检测模型,在先验多普勒频率范围内提高阅读绘本器发音准确性检测能力。仿真结果表明,采用该方法进行阅读绘本器发音检测的准确概率较高,虚警概率较小,提高了阅读绘本器的语音交互和动态特征分析能力。
The pronunciation accuracy of reading picture books is the key to improve the quality of reading picture books.This paper puts forward a method to build the pronunciation accuracy detection model of reading picture books based on voice interaction.The voice sensor is used to detect the voice information of the picture book reader,the picture book reader pronunciation voice signal model is established,the picture book reader pronunciation voice feature detection and spectrum analysis are carried out by digital filtering detection method,the picture book reader pronunciation voice feature detection and noise separation model is established by voice interaction and voice enhancement method,the optimal picture book reader pronunciation voice signal detection model is established under a given false alarm probability,and the pronunciation accuracy detection ability of the picture book reader is improved within the range of prior Doppler frequency.The simulation results show that this method has higher accurate probability and lower false alarm probability in pronunciation detection of picture book reader,which improves the ability of speech interaction and dynamic feature analysis of picture book reader.
