Mehri ejective fricatives: an acoustic study Rachid Ridouane, Cédric Gendrot, Rajesh Khatiwada Laboratoire de Phonétique et Phonologie (CNRS/Sorbonne Nouvelle), Paris ABSTRACT sequence of a pulmonic fricative followed by a glottal stop [3]. The second strategy, observed in Ejective consonants are not very common cross- Tlingit, was to produce ejective fricatives with a linguistically. Even less common is the occurrence much narrower constriction than was used in their of ejective fricatives. This infrequency is generally pulmonic counterparts [4]. This allowed for glottal attributed to the incompatibility of two aerodynamic closure to overlap the entire frication duration while requirements: a continuing flow of air to create noise producing high intra-oral pressure, suggesting that frication and an increasing intraoral air pressure to they were indeed ejective fricatives. This ‘canonical’ implement ejectivity. This study reports on an ejection of a fricative translated acoustically into acoustic investigation of initial and intervocalic shorter duration and a tendency for "scrapiness" or ejective fricatives in Mehri, a Modern South Arabian pulsing during frication noise. Similar to what has language spoken in Oman, and seeks to determine been observed in Tigrinya, Tlingit ejectives also how this incompatibility is solved by the 5 subjects displayed (near-)silent periods preceding frication recorded. The analysis of different temporal and noise. The interpretation of this silent gap differed, non-temporal parameters shows a high degree of however. While [4] interpreted it as glottal closure, variability in the way this contrast is implemented. [3] provided some evidence that the source of this Much of this variability is shaped by the position of closure is oral. the fricatives within the word. The phonetic implementation of ejective fricatives has been instrumentally examined in some other Keywords: Ejective fricatives, Mehri, Modern languages, including Amharic, Kabardian, Lowland South Arabian language. Oaxaca Chontal, and Upper Necaxa Totonac. In a survey of the characteristics of ejective fricatives in 1. INTRODUCTION these languages, [3] showed that they acoustically displayed shorter and ‘scrapy’ frication noise, Ejectives occur in about 16% of the world languages generally preceded and/or followed by a silent (92 out of 576) [1]. Ejective fricatives are more interval. From aerodynamic and articulatory infrequently encountered; only 3.7% languages were perspectives, ejective fricatives were shown to reported to have at least one such segment. This display higher intraoral pressure peaks, larger rarity is generally attributed to aerodynamic tongue-palate contact and narrower constriction. constraints that make them acoustically instable: the In the present study we report on an acoustic continuing flow of air necessary to the production of investigation of ejective fricatives in Mehri, a South frication is incompatible with the increasing of Arabian Language spoken in Oman. We provide intraoral air pressure necessary to the production of acoustic characteristics of these segments and show ejectivity [2, 3]. This raises the question of whether how native speakers solve the frication and ejectivity these segments are real ejective fricatives, or aerodynamic dilemma in light of what has been whether they should on closer examination prove to reported for other related and unrelated languages. be distinguished from their pulmonic counterparts by some other dimension. Faced with this question, 2. EJECTIVES IN MEHRI SYSTEM Shosted and Rose [3], based on acoustic data from Tigrinya, showed that ejective /s’/ was generally We begin with some background information on realized not as a fricative but as an affricate [ts’].

Two other strategies Mehri is a dialect of the Modern South Arabian to solve the incompatibility of tight glottal language, a subgroup of the Semitic branch of the constriction and frication have been reported. The Afroasiatic family. The dialect investigated in this first one, used by Yapese speakers, was to have a study is spoken in the province of Dhofar in Oman non-overlapping articulation by producing the by an estimated 50,000 native speakers. The ejective fricative not as a single segment but as a consonantal system of the language is given in table 1. In addition to voiceless and voiced stops and temporal characteristics that might acoustically fricatives, the langue has ejective stops as well as a differentiate [θ', s', ɬ', š'] from their pulmonic series of 4 ejective fricatives [θ', s', ɬ', š'].

METHOD Table 1: The consonantal system of Mehri [cf. 6]. 3.1. Speakers Five male Mehri native speakers aged from 20 to 27 (mean 22.2, SD 2.86) were recorded during a fieldwork in Salalah in southern Omani province of Dhofar. All of the participants reported being able to speak Omani Arabic and Standard Arabic, as is common for native Mehri speakers. None of them had any known history of hearing or speech disorders at the time of recordings. 3.2. Procedure Table 1 shows the data used in this study. It consisted of 4 pairs of triliteral consonant roots contrasting Ejectives were shown to pattern together with each ejective fricative with its pulmonic counterpart uvulars and pharyngeals as a natural class defined by (a larger data was recorded including filler items and the feature [+ low]. This class of segments triggers items contrasting ejective stops with their non- the diphtongization of following long high vowels ejective counterparts). Each root was conjugated in /i:/ and /u:/ to [aj] and [aw], respectively, and the three verbal paradigms (perf. 3ms, imperf. 3ms, subj. lowering of long /e:/ into /a:/ [5, 6]. 3ms) and produced within a carrier sentence before A large amount of variability was reported in the them. Only the first two verbal forms were analyzed, realization of Mehri ejective segments, depending on yielding data with ejective and pulmonic fricatives in dialectal origin, place of articulation, manner of word-initial and word-medial intervocalic positions. articulation, and word position [5, 7-10]. This raised The third verbal forms contained word-final ejectives some debate as to whether the description of these not examined here. segments as ejectives was, in fact, correct. For [5], for example, only /s’/ showed ejective tokens Table 2: List of Mehri items utterance-initially and -finally. Otherwise, it was Root Perf. 3ms Imperf, 3ms realized as an emphatic or dorsopharyngealized /sbH/ səbu:H isu:bəH “to fix” consonant. For the other fricatives, the reported /s’br/ s’əbu:r is’u:bər “to support” unmarked realization was emphatic. The interdental /θbr/ θəbu:r iθu:bər “to break” fricative was, for example, reported to be invariably /θ’br/ θ’əbu:r iθ’u:bər “to blame” pharyngealized in all environments. This has lead /ɬbr/ ɬəbu:r iɬu:bər “to measure” some researchers to argue for a gradual sound /ɬ’bl/ ɬ’əbu:l iɬ’u:bəl “to drink” change which may switch, given the overwhelming /ʃbl/ ʃəbla iʃabla “to swallow” influence of Arabic, from a contrast of ejectivity to a /ʃ’rm/ ʃ’əru:m iʃ’u:rəm “to slap” contrast of dorsopharyngealization [7, 10]. Most of these reports on Mehri ejectives were Target fricatives in initial position were followed by limited to dialects spoken in Yemen. They also a schwa vowel.
