语音加工的功能性近红外脑成像研究进展

摘要

功能性近红外光谱技术（ fNIRS）是近十多年兴起的一种用于研究脑功能成像的新手段。与其他研究手段相比，它具有便于移动、造价低、对运动伪迹不敏感等优势。本文首先简要介绍 fNIRS 技术的原理、算法类型、应用与特点，然后总结了 fNIRS在语音加工领域的研究进展，其中包括音长、音位序列、音节结构、重音、语调等内容，最后基于已有成果与研究现状，对 fNIRS在中文语音加工方面的应用提出了展望。%As a new technology of functional brain imaging, Functional Near Infrared Spectroscopy Technology ( fNIRS) have been developing for more than ten years.Compared with other imaging research methods, its advantages are obvious:easy-to-move, low cost, relatively non-sensitive to motion artifact.This paper first introduced the principle of fNIRS technology, algorithm type, application and its characteristics, and then summarized the progress in the field of speech processing with fNIRS, including sound length, sequence of phonemes, syllable structure, stress, intonation, etc.Finally, based on previous studies, a few suggestions for the development of Chinese phonological processing with fNIRS were proposed.
