TL;DR: An acoustic study of the amplitude modulation of the frication component when voicing is present, which reveals a pattern, consistent across speaking style, speaker, and place of articulation, for modulation at fo to rise at low voicing strengths and subsequently saturate.
Abstract: The two principal sources of sound in speech, voicing and frication, occur simultaneously in voiced fricatives as well as at the vowel-fricative boundary in phonologically voiceless fricatives. Instead of simply overlapping, the two sources interact. This paper is an acoustic study of one such interaction effect: the amplitude modulation of the frication component when voicing is present. Corpora of sustained and fluent-speech English fricatives were recorded and analyzed using a signal-processing technique designed to extract estimates of modulation depth. Results reveal a pattern, consistent across speaking style, speaker, and place of articulation, for modulation at f0 to rise at low voicing strengths and subsequently saturate. Voicing strength needed to produce saturation varied 60–66dB across subjects and experimental conditions. Modulation depths at saturation varied little across speakers but significantly for place of articulation (with [z] showing particularly strong modulation) clustering at app...

TL;DR: The role of the larynx in the production of voiced and voiceless stops and fricative consonants is discussed in this article. But the evidence is negative so far as providing support for a view that this latter feature plays a significant role in the voicing distinction.

TL;DR: The results show that the relative role of secondary cues and duration may differ across consonants and that gemination may involve language-specific phonetic knowledge that is specific to each consonant, and question the idea that lexical access in speech processing can be achieved through features.

TL;DR: It is suggested that the direction of short-duration fundamental frequency perturbations following consonants helps to signal consonant [+voice]/[––voice] (abbreviated as [voice]) status, and it is proposed that the [voice] cue corresponds to the direction and extent of F₀ perturbation relative to the overall intonation contour.
Abstract: Previous research has suggested that the direction of short-duration fundamental frequency (F0) perturbations following consonants helps to signal consonant [+voice]/[-voice] (abbreviated as [voice]) status. It has been proposed that the [voice] cue corresponds to the direction and extent of F0 perturbations relative to the overall intonation contour. A competing view, the low-frequency hypothesis, suggests that F0 participates in a more general way whereby low-frequency energy near the consonant contributes to [+voice] judgments. Listeners identified multiple stimulus series, each varying in voice onset time and ranging from /aga/ to /aka/. The series differed in overall intonation contour as well as in the direction of F0 perturbation relative to that contour. Consistent with one version of the low-frequency hypothesis, the F0 value at voicing onset, rather than the relative direction of the F0 perturbation, was the best predictor of [voice] judgments.

TL;DR: The authors argue that the instability of Japanese voiced stops under gemination may also be attributed to the phonological system of Japanese and propose a phonetic account grounded in perception for the variable patterning of voiced stops.
Abstract: In loanwords in Japanese, a consonant gemination process is frequently found. While voiceless stops consistently geminate and are voiceless in the appropriate environment, voiced stops may geminate as voiced stops, may fail to geminate, or may geminate as voiceless stops. A phonetic account grounded in perception has been proposed for the variable patterning of voiced stops under gemination conditions. I argue that while this is a possible explanation, the instability of voiced stops under gemination may also be attributable to the phonological system of Japanese. Thus, the role of perception in the variable patterning of voiced stops remains an open question.
