Computer methods, based on the theory and application of signal processing, combined with numerical methods for simulating mathematical processes, facilitate greater objectivity in most aspects of speech intelligibility testing, including specification of the stimuli, control of the tests, evaluation of the responses, corrective feedback, and automatic interpretation. This paper discusses several basic issues in digital signal processing, and also describes the application of computer-aided procedures for recording and delivery of speech materials for audiologic research. Examples of the use of computer procedures for manipulation of digitized stimuli demonstrate the increased efficiency and versatility of these procedures compared to more conventional tape recording methods. In addition, the use of digitized recordings allows more reliable specification of speech levels than conventional calibration methods involving observations of signal peaks on a VU-meter.
基于信号处理理论与应用的计算机方法，结合用于模拟数学过程的数值方法，有助于在言语可懂度测试的大多数方面实现更高的客观性，包括刺激的规范、测试的控制、反应的评估、纠正反馈和自动解释。本文讨论了数字信号处理中的几个基本问题，并描述了计算机辅助程序在听力学研究中语音材料记录与传递方面的应用。与更传统的磁带记录方法相比，使用计算机程序处理数字化刺激的示例展示了这些程序更高的效率和通用性。此外，与涉及观察VU表上信号峰值的传统校准方法相比，使用数字化录音能够更可靠地确定语音电平。
