摘要
噪声环境下的言语识别是人工耳蜗使用者面临的一个难题,目前已提出了多种技术方法用于改善这一问题。麦克风阵列语音增强技术是其中之一,旨在通过改进人工耳蜗前端信号采集系统性能,提高信噪比提升人工耳蜗使用者噪声下的言语识别能力,具有较好的临床应用价值。本文介绍了麦克风阵列与语言增强技术的基本原理、临床应用效果、存在的问题和未来展望,以期为深入探索技术创新对改善人工耳蜗使用者噪声下言语可懂度提供参考。
Cochlear implant users face challenges in speech recognition in noisy environments.Various technologies and methods have been proposed to address this issue.One such solution is the use of microphone array speech enhancement technology,which aims to amplify the sound from the front and suppress noise from the sides and rear,thereby improving the signal-to-noise ratio.This paper introduces the fundamental principles of microphone arrays and speech enhancement technology,evaluates their effectiveness in clinical applications,and discusses current issues and future developments.The goal is to serve as a reference for exploring technological innovations aimed at improving speech intelligibility for cochlear implant users in noisy environments.
