“…A number of different factors have been reported in the literature as having an influence in the maintenance of voicing. These have determined our choice of word and sentence contexts, namely: place of articulationvoicing may cease earlier for more posterior places of articulation; word-position-from an aerodynamic point of view a voiced obstruent is more likely to be produced in medial position, whereas in utterance initial and final position it is more probable to produce devoiced items; consonant duration-the longer the consonant duration, the more probable is that voicing ceases; context-stops coarticulated with high vowels maintain voicing longer than when coarticulated with low vowels [42].…”

“…Matlab 7.5.0 (R2007b) and Praat Version 5.0.4 scripts were used to extract the following metrics, based on average values calculated from 10 to 20 ms windows centred within the phones: absolute (cm 3 /s) and relative (%) oral airflow of voiced stops and vowels. Oral airflowbased parameters have been shown to be useful and reliable when one is trying to understand the production mechanisms of voiced obstruents [42,43]. Thus, the choice of parameters in the current paper.…”

Experimental data combining complementary measures based on the oral airflow signal is presented in this paper, exploring the view that European Portuguese voiced stops are produced in a similar fashion to Germanic languages. Four Portuguese speakers were recorded producing a corpus of nine isolated words with /b, d, ɡ/ in initial, medial and final word position, and the same nine words embedded in 39 different sentences. Slope of the stop release (SLP), voice onset time (VOT), release and stop durations and steady-state oral airflow amplitude characteristics preceding and following the stop were analysed. Differences between independent groups (three different places of articulation and two vowel contexts) and correlations between variables were studied; generalised linear mixed effects models were developed to study the effects of VOT, SLP and the factors place of articulation and vowel context on the mean oral airflow. A classification of stop's voicing was automatically extracted. Both SLP (p = .013) and VOT (p = .014) were significantly different for the three places of articulation. Weak voicing was observed for 57% of the stops. It is hypothesised that the high percentages of weakly voiced stops are a consequence of passive voicing and that the feature of contrast in Portuguese is privative [spread glottis].

“…Some of the data for these studies were collected in the field, given the portability of EGG. Many studies have combined EGG with other articulatory methods, such as, for example, with nasalance and ultrasound (Carignan, 2018), oral airflow (Pinho, Jesus, & Barney, 2012), and endoscopy (Brunelle, Nguyên, & Nguyên, 2010; Moisik, Esling, & Crevier‐Buchman, 2010).…”

This article is Part II of a general overview of current methods in articulatory phonetics research (which also consists of Part I "Research methods in articulatory phonetics I: Introduction & studying oral gestures"). The article begins by examining methods employed by phoneticians to investigate laryngeal and nasal gestures-speech-related configurations of the glottis and the lowering/raising the velum for nasal/oral consonants and vowels. This is done by reviewing the methods of electroglottography, endoscopy, photoglottography, and measurements of airflow and air pressure. The article further examines magnetic resonance imaging and radiography (X-rays)-the methods employed to investigate the entire vocal tract. The review is concluded with the methods of video recording and optical tracking, as used to study manual gestures in speech and sign language. Each methodological section contains a review of relevant journal publications illustrating the application of the method, as well as references to further readings. The article concludes with an overview of current developments and trends in instrumental articulatory phonetics, and highlight issues requiring further research.

“…Acoustic and articulatory characteristics of voicing differ from one language to another (Browman and Goldstein, 1986;Dagenais et al, 1994;Docherty, 1992;Fuchs, 2005;Fuchs et al, 2007;Gordeeva and Scobbie, 2007;Liker et al, 2012;Pinho et al, 2012). For example, in languages like English or German it is common for phonologically voiced obstruents to be partially or completely voiceless phonetically, while in languages like Czech or Croatian this process is much less common (Bakran, 1996;Skarnitzl et al, 2013).…”

Although numerous studies have investigated supraglottal strategies for signalling voicing in fricatives, there is still no agreement about the precise characteristics of tongue-to-palate contact timing during voiced as opposed to voiceless fricatives. In this study we use electropalatography (EPG) to investigate articulatory and coarticulatory characteristics of tongue-to-palate contact timing during /s/ and /z/ in English. Five typically speaking participants, speakers of Southern British English, produced 500 trochaic words containing the intervocalic alveolar fricatives /s/ or /z/. The time between the start of the frication and the maximum contact at the place of articulation was expressed as a percentage of each fricative's total duration (time to target, TT).This measure was used to analyse articulatory and coarticulatory timing during /s/ and /z/. Data for absolute timing were also presented. The results showed that the time between the start of the frication and the maximum contact point was longer for /s/ than for /z/. This difference was consistent across speakers but was not significant for all of them. The results of the coarticulatory effects showed that the influence of vowel context on TT values for /s/ and /z/ did not differ significantly, but there was a tendency for /z/ to be more resistant to coarticulation effects than /s/.
