我们介绍了南加州大学语音和声道形态MRI数据库，一个17个说话人的磁共振成像数据库，用于语音研究。该数据库包括动态声道成形的实时磁共振图像(RtMRI)，与rtMRI同时记录的去噪音频，以及持续语音期间声道形状的3D体积MRI。我们获得了辅音-元音-辅音序列、元音-元音序列、朗读段落和自发语音过程中声道成形的2D实时磁共振成像。我们获得了美式英语全套元音和连续辅音的3D体积磁共振成像。每个3D体积磁共振成像都是在参与者保持声音的一次7秒扫描中获得的。这是第一个将动态声道成形的rtMRI和整个声道的3D体积MRI结合在一起的数据库。该数据库为研究声道形态和声道功能之间的关系提供了独特的资源。南加州大学语音和声道形态核磁共振数据库免费提供给http://sail.usc.edu/span/morphdb.进行研究使用
We present the USC Speech and Vocal Tract Morphology MRI Database, a 17-speaker magnetic resonance imaging database for speech research. The database consists of real-time magnetic resonance images (rtMRI) of dynamic vocal tract shaping, denoised audio recorded simultaneously with rtMRI, and 3D volumetric MRI of vocal tract shapes during sustained speech sounds. We acquired 2D real-time MRI of vocal tract shaping during consonant-vowel-consonant sequences, vowelconsonant-vowel sequences, read passages, and spontaneous speech. We acquired 3D volumetric MRI of the full set of vowels and continuant consonants of American English. Each 3D volumetric MRI was acquired in one 7-second scan in which the participant sustained the sound. This is the first database to combine rtMRI of dynamic vocal tract shaping and 3D volumetric MRI of the entire vocal tract. The database provides a unique resource with which to examine the relationship between vocal tract morphology and vocal tract function. The USC Speech and Vocal Tract Morphology MRI Database is provided free for research use at http://sail.usc.edu/span/morphdb.
