Abstract: A voice quality evaluation method, apparatus, and system comprises an obtained voice data packet is parsed, and a frame content characteristic of the data packet is determined according to a parse result, for example, the frame content characteristic is a silence frame and a voice frame. Then, a voice sequence is divided into statements according to the determined frame content characteristic, and the statements are divided into multiple frame loss events; after non-voice parameters are extracted according to the frame loss events, voice quality of each statement is evaluated according to a preset voice quality evaluation model and according to the non-voice parameters. Finally, voice quality of the entire voice sequence is evaluated according to the voice quality of each statement. By using this solution, prediction precision can be improved significantly, and accuracy of an evaluation result can be improved.
Abstract translation: 语音质量评估方法，装置和系统包括所获得的语音数据分组被解析，并且根据解析结果确定数据分组的帧内容特征，例如，帧内容特征是静默帧和语音 帧。 然后，根据确定的帧内容特征将语音序列划分成语句，并将语句划分为多个帧丢失事件; 在根据帧丢失事件提取非语音参数后，根据预设的语音质量评估模型和非语音参数对每个语句的语音质量进行评估。 最后，根据每个语句的语音质量来评估整个语音序列的语音质量。 通过使用该解决方案，可以显着提高预测精度，可以提高评价结果的准确性。
