Model training method and device, speaking topic evaluation method and device and computer storage medium

The invention provides a model training method and device, a speaking topic evaluation method and device and a computer storage medium. The model training method comprises the following steps: acquiring to-be-evaluated voice and corresponding evaluation content; extracting an audio sequence and a text sequence of the to-be-evaluated voice; obtaining a prediction evaluation score of the to-be-evaluated voice based on the voice prediction features of the audio sequence and the semantic prediction features of the text sequence and the evaluation content; and training the topic evaluation model according to the real evaluation score and the predicted evaluation score of the to-be-evaluated voice. Through the above mode, the voice prediction features and the semantic prediction features are used, and the scoring accuracy is improved. 本申请提出一种模型训练、说话题评测方法、装置及计算机存储介质。所述模型训练方法包括：获取待评测语音，以及对应的评测内容；提取所述待评测语音的音频序列和文本序列；基于所述音频序列的语音预测特征和所述文本序列以及所述评测内容的语义预测特征，获取所述待评测语音的预测评测分数；按照所述待评测语音的真实评测分数和预测评测分数，对所述说话题评测模型进行训练。通过上述方式，使用
