The effect of reducing low-frequency modulations in the temporal envelope on the speech-reception threshold (SRT) for sentences in noise and on phoneme identification was investigated. For this purpose, speech was split up into a series of frequency bands (1/4, 1/2, or 1 oct wide) and the amplitude envelope for each band was high-pass filtered at cutoff frequencies of 1, 2, 4, 8, 16, 32, 64, or...

Australian English /t/ has a fricative realisation in some contexts. The presence of an additional surface fricative in the language raises questions about potential merger and the maintenance of contrasts. An orthographic representation of fricated /t/ as 〈sh〉 suggests a similarity to the existing fricative /S/. This paper compares the acoustic characteristics of fricated realisations of /t/ i...

An acoustic analysis of the uvular unvoiced fricative in intervocalic sequences, as spoken in Arabic, is presented. Properties of both the noise region and voiced boundaries are examined, and several attributes are discovered: the glottal waveform changes considerably during its transition between the vowels and the fricative boundaries, with the open quotient becoming 100% at the boundaries co...

This study examined whether compensation for coarticulation in fricative-vowel syllables is phonologically mediated or a consequence of auditory processes. Smits (2001a) had shown that compensation occurs for anticipatory lip rounding in a fricative caused by a following rounded vowel in Dutch. In a first experiment, the possibility that compensation is due to general auditory processing was in...

When synthetic fricative noises from a [f]-[s] continuum are followed by [a] or [u] (with appropriate formant transitions), listeners perceive more instances of [s] in the context of [u] than in the context of [a]. Presumably, this reflects a perceptual adjustment for the coarticulatory effect of rounded vowels on preceding fricatives. In Experiment 1, we found that varying the duration of the ...

Previous studies have shown that spoken-language processing is inhibited by violation of obligatory regressive assimilation. Weber (2001) replicated this inhibitory effect in a phoneme-monitoring study examining regressive place assimilation of nasals, but found facilitation for violation of progressive assimilation. German listeners detected the velar fricative [x] more quickly when fricative ...

The coordination of gestures in consonant clusters differs across languages and hence must be a learned aspect linguistic knowledge. Precisely pinning down the relation used particular language, or for cluster type, has been facilitated by recent research showing that relations structure kinematic variation unique ways. We apply these methods to hitherto under-explored topic, created via vowel ...

The study illustrates the similarities and differences between Arabic Chinese phonetic systems through comparison. aims to explore pronunciation errors of consonants among students learning reasons behind errors. found that tend make consonants, finding it easy pronounce ? / h as x or /. Ultimately, could improve students' comprehensive understanding system avoid similar in consonants.

Cross-language differences in the use of coarticulatory cues for the identification of fricatives have been demonstrated in a phoneme detection task: Listeners with perceptually similar fricative pairs in their native phoneme inventories (English, Polish, Spanish) relied more on cues from vowels than listeners with perceptually more distinct fricative contrasts (Dutch and German). The present g...
