气流气压信号作为一种言语产生时重要的生理信号,在语音多模态研究中具有重要作用。由于气流气压信号在采集后只能保存为NSP文件,且只有信号采集器自带软件能够对其进行简单的处理,极大的限制了对该信号的分析和研究。鉴于此,本文在对气流气压信号进行分析的基础上,结合语音多模态研究实际需要,设计并实现了将NSP文件转换为WAV文件的程序,便于使用现有语音分析软件和信号处理的方法对该信号进行处理,促进了对气流气压信号更深层次的研究。
Airflow pressure signal, as an important physiological signal when speech is produced, plays an important role in the study of speech multimodality. Since the air pressure signal can only be saved as an NSP file after being collected, and only the signal acquisition software provided by the signal collector can simply process it, which greatly limits the analysis and research of the signal. In view of this, based on the analysis of the air pressure signals and combining with the actual needs of multi-modal voice research, this paper designs and realizes the program of converting NSP files into WAV files, and facilitates the use of existing voice analysis software and signal processing methods The signal is processed to promote a deeper understanding of the gas pressure signal.
