本文探讨了阿根廷西班牙语摩擦音的声学特性和识别这些辅音的频谱线索。据观察，[s]在5000和8000 Hx附近出现频谱峰值，[公式：见正文]在2500和5000 Hz附近出现频谱峰值，[f]在1500和8500 Hz附近出现频谱峰值，[x]在1000和4000 Hz附近出现频谱峰值，[f]在2000和4000 Hz附近出现频谱峰值。通过滤波和合成实验来确定这些谱峰中的每一个的感知重要性。关于语音摩擦音：[beta，，Y，Y，3]，分析显示具有相似频率的F1和变量F2的周期性成分。具有相似频率的F1和可变F2的噪声分量。噪声成分主要在[3]中观察到。浊擦音比清擦音短。对辅音-元音音节中摩擦音的分析表明，摩擦音和元音部分都可能提供相关的声学线索。为了验证这一点，我们进行了磁带拼接实验，结果表明，除了[x]和[Y]之外，所有的西班牙摩擦音都可以通过摩擦音部分准确识别。然而，它也被观察到，在过渡音节的元音部分影响语音识别的摩擦部分。这一现象表明，在某些摩擦音和元音的组合过渡的知觉相关性。
This paper examines the acoustic properties of Argentine Spanish fricatives and the spectral cues in recognition of these consonants. It was observed that [s] spectrally peaks around 5000 and 8000 Hx, [formula: see text] around 2500 and 5000 Hz, [f] around 1500 and 8500 Hz, [x] around 1000 and 4000 Hz and [ç] around 2000 and 4000 Hz. The perceptual importance of each of these spectral peaks was determined by filtering and synthesis experiments. With regard to the voice fricatives: [beta, ŏ, Y, Y, 3] the analysis showed periodic components with an F1 of similar frequency and a variable F2. Noise components with an F1 of similar frequency and a variable F2. Noise components were principally observed in [3]. Voiced fricatives proved to be shorter than voiceless ones. The analysis of fricatives in consonant-vowel syllables suggested that both the friction and vocalic portions may provide relevant acoustic cues. Tape-splicing experiments, designed to test this observation, showed that except for [x] and [Y], all Spanish fricatives were accurately identified by the friction portion alone. However, it was also observed that in transitionless syllables the vocalic portion affected the phonetic identification of the friction portion. This phenomenon pointed to the perceptual relevance of the transition in some combinations of fricatives and vowels.
