自然发音音节/fi/和/θi/中的发音声母/f/和/θ/被拼接--在/S/和/f/两个发音音节中都剪掉了/si/和/∫i/音节的噪声。替换噪声的强度已衰减到原始/f/和/θ/噪声的水平。自然发音/f/或/θ/分别取决于原始摩擦音是/f/还是/θ/。这一程序以前曾被作者用来处理音间摩擦(J.Acoust.SoC。上午好。63，S21(A)(1978)]结果相似。这些结果表明，口语中的/f/或/θ/较低的噪声强度使它们有别于/S/和/∫/。在口语/f、θ、S、∫/中物理表现的噪声频谱变化范围对/f/和/θ/似乎没有知觉意义，它们通过音节发声部分的共振峰转换线索相互区分。然而，噪声频谱的差异是区分/S/...的重要线索
The noise of utterance initial/f/ and /θ/ in naturally spoken syllables /fi/ and /θi/ was replaced by splicing‐in both /s/ and /f/ noise cut away from spoken /si/ and /∫i/ syllables. The intensity of the replacing noise had been attenuated to the level of the original /f/ and /θ/ noise. A natural sounding /f/ or /θ/ resulted depending upon whether the original fricative had been /f/ or /θ/, respectively. This procedure was previously utilized by the author in relation to intervocalic fricatives (J. Acoust. Soc. Am. 63, S21(A) (1978)] with similar results. These results suggest that the lower noise intensity of spoken /f/ or /θ/ distinguishes them from /s/ and /∫/. The range of noise spectrum variation which is physically manifest in spoken /f, θ, s, ∫/appears to have no perceptual significance for /f/ and /θ/, which are distinguished from each other by the formant transition cues of the vocalic portion of the syllables. However, noise spectrum differences are important cues in the distinction between /s/ ...
