Abstract
A form of processed speech is described that is highly discriminable in a closed-set identification format. The processing renders speech into a set of sinusoidal pulses played synchronously across frequency. The processing and results from several experiments are described. The number and width of frequency analysis channels and tone-pulse duration were variables. In one condition, various proportions of the tones were randomly removed. The processed speech was remarkably resilient to these manipulations. This type of speech may be useful for examining multitalker listening situations in which a high degree of stimulus control is required.
摘要
描述了一种在封闭集识别格式中具有高度可辨性的处理后的语音。该处理将语音转换为一组在频率上同步播放的正弦脉冲。描述了处理和几个实验的结果。频率分析通道的数量和宽度以及音调脉冲持续时间是变量。在一种条件下，随机删除了各种比例的音调。处理后的语音对这些操作具有很强的弹性。这种类型的语音可能有助于研究需要高度刺激控制的多说话人聆听情况。
