Identity identification method and system based on voiceprint in motion state

The invention discloses a voiceprint identity identification method and system based on a motion state, and the method comprises the steps: firstly obtaining a voice detection material, and carrying out the analysis to obtain the motion state of a speaker; the method comprises the following steps of: acquiring a voice sample, converting the voice sample into a broadband speech graph, selecting N phonemes, performing identity analysis by adopting any one or a combination of more of a formant trend characteristic analysis method, a formant frequency characteristic analysis method and an intra-syllable transition phoneme analysis method after the number of the phonemes meets an identification condition, and outputting a voiceprint identification result. The method is suitable for voiceprint identification in different motion forms, is convenient for online use, and greatly improves the efficiency and accuracy of identification. 本申请公开了一种基于运动状态下声纹的同一性鉴定方法及系统，其中方法包括：首先获取语音检材，分析得到发音人运动状态；再将语音检材和语音样本转换为宽带语图，选择N个音素，当音
