The region of Béarn denotes the historically Romance-speaking part of the modern-day Pyrénées-Atlantiques département in south-western France. The langue d’oc or southern Gallo-Romance variety historically spoken in Béarn, commonly referred to as ‘Béarnais’, is a dialect of Gascon. This variety may also be referred to by its autoglossonym ‘Biarnés’ though the French term is the most widely used designation for the regional language. The number of Gascon speakers in south-western France increases steadily from north (Bordeaux) to south (the Pyrenees) and because Béarn is the area of linguistic Gascony with the highest recorded number of Gascon speakers (Moreux 2004), Béarnais may be considered the principal surviving dialect of Gascon, though other surviving dialects, such as ‘Gascon de Chalosse’, and ‘Landais’, are still spoken and written.

Cicipu ([tʃìtʃípù], ISO 639–3 code awc) is spoken by approximately 20,000 people in northwest Nigeria, with the main language area straddling the boundary between Kebbi and Niger states. The language belongs to the Kambari subgroup (not Kamuku as stated by Lewis, Simons & Fennig 2013) of Kainji (Benue-Congo), although it is heavily influenced by the lingua franca Hausa, in which almost all speakers are fluent. There are several identifiable dialects, with native speakers of Cicipu generally listing seven. Of these, Tirisino is the most prestigious and least endangered dialect, and this is the one presented here. Tikumbasi is the most divergent of the dialects, with the /o/ vowel in the other dialects consistently corresponding to /e/ in Tikumbasi (for example /póːpò/ ‘hello’ ~ /péːpè/, /tʃìkóːtò/ ‘drum’ ~ /tʃìkʷéːtè/). The distinction between /o/ and /ɔ/ has been lost in Tikumbasi.

Sahaptin is a Sahaptian language spoken in Washington and Oregon, U.S.A. Rigsby & Rude (1996) divide Sahaptin into three broad dialect areas: Northwest, Northeast, and Columbia River. This Illustration of the IPA reflects the Yakama (also spelled Yakima) subdialect (ykm) of Northwest Sahaptin. Sahaptin has fifty or fewer native speakers (Beavert & Jansen 2012). The second author is a native speaker of this dialect. Her voice is on the accompanying recordings.

Romani is an Indo-Aryan language spoken in several European countries as well as in the Americas, Asia and Australia, showing substantial dialectal variation. This illustration deals with Xoraxane Romane (Turkish Romani) spoken in Greek Thrace. Xoraxane Romane, which belongs to the Vlax branch of Romani, has been heavily influenced by contact with Turkish and also shows influences from Greek. As a result, Xoraxane Romane exhibits a mixed system that includes phonemes borrowed from both Turkish and Greek but without exhibiting complex phonological phenomena such as Turkish vowel harmony.

In Malaysia, Kedayan (ISO code ‘kxd’) speakers are found primarily in the state of Sabah, the state of Sarawak, and the federal territory of Labuan, which is an offshore island near Sabah. Lewis (2009) classifies Kedayan as one of the many Malayic dialects within the Malayo-Polynesian branch of Austronesian languages.

Pitjantjatjara is a dialect of the Western Desert Language (WDL) of central Australia (Douglas 1958). The Western Desert Language is a member of the south-west Pama-Nyungan group. Together with Warnman, it forms the Wati sub-group. It is spoken by 4000–5000 people, and covers the widest geographical area of any language in Australia, stretching from Woomera in central northern South Australia, as far west as Kalgoorlie and Meekatharra and north to Balgo Hills, in Western Australia. The main dialects, which differ most in regards the lexicon but also to some extent in grammar and phonology, include Pitjantjatjara, Yankunytjatjara, Ngaanyatjarra, Ngaatjatjarra, Southern Luritja, Pintupi-Luritja, Kukatja, Gugarda, Ngalia, Wangkatja, Wangkatha, Manyjilyjarra, Kartutjarra and Yurlparija. It is perhaps more accurately conceived of as a dialect chain, whereby a dialect such as Pitjantjatjara is mutually intelligible with its neighbours Ngaanyatjatjarra and Yankunytjatjara, but not with dialects more distant than these, such as Kukatja and Manyjilyjarra.

Berber (or Tamazight) is an Afro-Asiatic language spoken by an estimated 15–25 million in North Africa. It is mainly spoken in Morocco, Algeria, and by the Touareg population in Niger and Mali. Berber is also a native language of populations living in Libya, Tunisia and Egypt, though their numbers are less significant. Large Berber communities also live in Diasporas mainly in France, Spain, Holland, and Belgium. Three varieties of Berber are spoken in Morocco: Tarifit, spoken in northern Morocco, Tamazight, spoken in the Middle-Atlas, and Tashlhiyt, spoken in southern Morocco. Tashlhiyt, the variety presented here, is sufficiently homogeneous for all native speakers, who number an estimated 7–9 million, to communicate without difficulties (Stroomer 2008). There is nonetheless a measure of sub-dialectal variation, which affects mainly the way some stop consonants are produced. Three subsystems, corresponding roughly to three distinct geographical locations, can be identified: the ‘occlusive’ subsystem spoken in Agadir and its suburbs, the ‘fricative’ subsystem spoken mainly in the High-Atlas area, which spirantizes noncoronal obstruents /bkg/ in some contexts, and the ‘sibilant’ subsystem spoken in the Anti-Atlas area, where /t/ and /d/ are realized in some contexts as [s] and [z], respectively (Boukous 1994). This study is based on the speech of Tashlhiyt speakers who originate from Agadir. The text of ‘The North Wind and the Sun’ was read by a 27-year-old female speaker.

Standard Tajik, or Modern Literary Tajik as it was called during the Soviet era, was established in the nineteen twenties and thirties based largely on the dialects of the Bukhara-Samarkand area, which was at the time the undisputed cultural centre of the Tajik-speaking population. Dushanbe, the current capital of Tajikistan, was then a small village with a population of only a few hundred and had no cultural heritage comparable to that of Bukhara or Samarkand. Bukharan Tajik, whose phonology is described in this paper, is a variety of Tajik that played a particularly influential role in the phonological standardization of Tajik, which took place for the most part in 1930. For instance, the Scientific Conference of Uzbekistan Tajiks of 1930 resolved that the dialect of Bukhara must be the designated basis of the sound and orthography of literary Tajik (вaroji tajjorī вa kanfiransijaji ilmiji istalinoвod 1930: 2). In August the same year, the Linguistic Conference held in the then newly established Tajik Soviet Socialist Republic also adopted a similar resolution that establishes the ‘language of the Tajiks of Samarkand and Bukhara’ as the reference point in establishing the literary (i.e. standard) pronunciation (Halimov 1974: 126). According to Bergne (2007: 82), ‘the same Linguistic Conference of 22 August 1930 in Stalinabad decided that the phonetic base for the language had better be the dialect of Bukhara’. Thus, the Bukharan Tajik of today is the direct descendant of the variety of Tajik which served as a primary basis of standard Tajik phonological norms; and hence differs little from standard Tajik phonologically and phonetically.

Cocos Malay, hereafter called Cocos, is referred to in the Ethnologue with the ISO code of ‘coa’. The Ethnologue considers Cocos to be a Malay-based Creole along with several other Malay-based creoles (Lewis 2009). Cocos is spoken in Australia and in Malaysia. In Australia, it is spoken on the islands of Cocos and Christmas with a total combined population of about 700 speakers on those two islands. In Malaysia, Cocos speakers are found primarily in the eastern and southeastern coastal districts of Sabah (Kunak, Semporna, Lahad Datu and Tawau). In early 2013, the Ethnologue listed the population of Cocos speakers in Malaysia as 4,000 and decreasing. The Ethnologue also stated that the total number of Cocos speakers in all places around the world is 5,000. However, both of these statements in the Ethnologue are not correct. The Cocos population in Malaysia is increasing, not decreasing, and the total worldwide population of Cocos speakers is much larger than the Ethnologue estimate. The 1970 population estimate for Cocos speakers in Malaysia was 2,731 (Moody 1984: 93, 100). But the 2012 population estimate for Cocos speakers worldwide is 22,400, with most Cocos speakers living in Sabah, Malaysia. Our study focused exclusively on Cocos speakers in Malaysia. Some Cocos speakers interviewed in our study claimed that their ancestors originated from the island of Cocos (also known as Keeling), southwest of Sumatra in the Indian Ocean. Others claimed that their ancestors originally inhabited the Indonesian islands of the Malay Archipelaɡo and subsequently migrated to Cocos Island and then to Sabah. Two historical accounts of the Cocos can be found in Nanis (2011) and Subiah, Rabika & Kabul (1981).

The Xumi 旭米 language (/EPʃʉ-hĩ ketɕɐ/ ‘the language of the Shu people’) is spoken by approximately 1,800 people who reside along the banks of the Shuiluo River (水洛河) in Shuiluo Township (水洛乡) of Muli Tibetan Autonomous County (木里藏族自治县; smi li rang skyong rdzong in Written Tibetan, hereafter, WT). This county is located in the South-West of Sichuan Province (四川省) in the People's Republic of China (see Figure 1).

This Illustration focuses on the variety of the Xumi language (旭米, /LPʂuketɕɜ/ or /EPʂu-hĩ ketɕɜ/) that is spoken in the upper reaches of the Shuiluo river (水洛河) in Shuiluo Township (水洛乡) (hereafter Upper Xumi). The township is located in Muli Tibetan Autonomous County (木里藏族自治县, smi li rang skyong rdzong in Written Tibetan, hereafter, WT), in the South-West of Sichuan Province (四川省) in the People's Republic of China.

Mennonite Plautdietsch (ISO 639–3: pdt) is a West Germanic (Indo-European) language belonging to the Low Prussian (Niederpreußisch) subgroup of Eastern Low German (Ostniederdeutsch), a continuum of closely related varieties spoken in northern Poland until the Second World War (Ziesemer 1924, Mitzka 1930, Thiessen 1963). Although its genetic affiliation with these other, now-moribund Polish varieties is uncontested, Mennonite Plautdietsch represents an exceptional member of this grouping. It was adopted as the language of in-group communication by Mennonites escaping religious persecution in northwestern and central Europe during the mid-sixteenth century, and later accompanied these pacifist Anabaptist Christians over several successive generations of emigration and exile through Poland, Ukraine, and parts of the Russian Empire. As a result of this extensive migration history, Mennonite Plautdietsch is spoken today in diasporic speech communities on four continents and in over a dozen countries by an estimated 300,000 people, primarily descendants of these so-called Russian Mennonites (Epp 1993, Lewis 2009).

This illustration focuses on the variety of Pashayi (also, Pashai) spoken in the Dara-i-Nur valley of Nangarhar Province, Afghanistan (approximately, N 34.682 E 70.581); the ISO 639-3 code for this variety is psi. According to Lewis (2009) there are 54,400 speakers of this variety, and about 216,000 speakers of all Pashayi dialects. The most comprehensive published study of Pashayi to date is Morgernstierne's two-volume grammar (Morgenstierne 1973, 1944), which is helpfully summarized in Bashir (2003).

Upper Saxon (Obersächsisch /ɵːpoˁˈsɛksʃ/) refers to a group of dialects spoken by over two million people in the Free State of Saxony in eastern Germany. It is considered one of the eastern branches of Central German (Wiesinger 1983, Lewis 2009), with major phonological, morphological, and lexical differences from Standard German and other regional dialects.

The Lizu (or Lüzu) language (/EPli-zu-hu/ or /EPly-zu-hu/) is spoken by approximately 7000 people who reside along the banks of the Yalong (雅 砻) or Nyag chu River in three counties in Sichuan Province (四 川 省) in the People's Republic of China: (i) Muli Tibetan Autonomous County 木 里 藏 族 自 治 县 (Written Tibetan, hereafter WT, smi li rang skyong rdzong), (ii) Jiulong county (九 龙 县 brgyad zur), (iii) Mianning county (冕 宁 县) (Wang 2010: 3).1 Lizu is currently considered as the western dialect of the Ersu 尔 苏 language (Sun 1982, 1983), which is in turn classified as a member of the Qiangic subgroup of the Tibeto-Burman language family (for more details, see Bradley 1997: 36–37; Sun 2001; Chirkova 2012).

Luxembourgish (local language name: Lëtzebuergesch [ˈlətsəbuəjəʃ], French name: Luxembourgeois, German name: Luxemburgisch) is a small West-Germanic language mainly spoken in the multilingual speech community of the Grand Duchy of Luxembourg, where it is one of the three official languages alongside German and French. Being the first language of most Luxembourgers it also has the status of the national language (since 1984). Although in its origin Luxembourgish has to be considered as a Central Franconian dialect, it is nowadays regarded by the speech community as a language of its own. As a consequence, German is considered a different language. An official orthographical system has been devised. Luxembourgish is used very frequently in day-to-day oral communication at all social levels; it is very common on local radio and television; it is the only language spoken in parliament sessions and it is also very often used at the workplace. Although the vocabulary of Luxembourgish has a substantial number of loan words from French and German, the morpho-syntax follows Germanic patterns. Luxembourgish today has approximately 400,000 speakers, including many L2 speakers (around 43% of the population does not have the Luxembourgish nationality).

Mapudungun (/mpʊðʊˈŋʊn/ or /mpʊθʊˈŋʊn/; also known as ‘Mapudungu’, ‘Mapuzugun’, ‘Mapuche’, ‘Mapuchedungun’, ‘Chedungun’ and ‘Araucanian’ or ‘Araucano’ (the latter two being archaic)) is a language isolate spoken actively by approximately 144,000 people in Chile (Zúñiga 2007), as well as by some 8,400 people in Argentina (Instituto Nacional de Estadísticas y Censos 2005), virtually all of whom are bilingual in Spanish. Its ISO 639–3 code is arn.

Shiwilu (a.k.a. Jebero) is a critically endangered language from Peruvian Amazonia and one of the two members of the Kawapanan linguistic family. Most of its nearly 30 remaining fluent speakers live in and around the village of Jeberos (District of Jeberos, Province of Alto Amazonas, Loreto Region), at approximately 5° S, 75° W.

The documentation of Shiwilu is scarce and no survey grammar is available. Until very recently, the only trained linguist who had worked on Shiwilu was John Bendor-Samuel, who carried out fieldwork in 1955–1956 and completed a doctoral thesis in 1958 (see Bendor-Samuel 1981 [1958]). An abridged version of the thesis, which includes an outline of the phonology, was published as Bendor-Samuel (1961). Whereas recent publications have focused on the social position of the Shiwilu language (Valenzuela 2010), morpho-syntactic aspects (Valenzuela 2011), and a formal demonstration of its family affiliation with the Shawi language (a.k.a. Chayahuita) (Valenzuela Bismarck 2011), the present article is the first account of its sound system since the work by Bendor-Samuel.

Tena Quichua (ISO 639-3: quw) belongs to the Quechuan language family, as part of the peripheral variety Quechua IIB (Torero 1964, Cerrón-Palomino 1987, Gordon 2005). It is spoken in the Eastern Amazonian region of Ecuador on the Napo River above the mouth of the Rio Coca, primarily on three tributaries: the Misahualli, the Arajuno, and the Ansuc. Tena Quichua is bounded on the North and East by Napo Quichua and on the South by Pastaza Quichua. Previous research on the division of Ecuadorian dialects is summarized by Carpenter (1984: 3–4). Although it is beyond the scope of this Illustration, we hope that our description of Tena Quichua will prove useful in future work on the relations between these three Amazonian dialects of Ecuadorian Quichua. Below, a brief summary of Tena dialect identification and formation is given, followed by a description of present-day bilingualism in the region and data collection procedures.

Bardi is the northernmost language of the Nyulnyulan family, a non-Pama-Nyungan family of the Western Kimberley region of northwestern Australia. Currently about five people speak the language fluently, but approximately 1,000 people identify as Bardi. The region was settled by Europeans in the 1880s and two missions were founded in Bardi country in the 1890s. Use of the language began declining in the 1930s. Many Bardi people were moved several times between 1940 and 1970, both to other missions dominated by speakers of other Indigenous languages and to local towns such as Derby. This community disruption accelerated the decline of language use in the community and first language acquisition. Bardi is the name of the language variety spoken at One Arm Point. There are two other named mutually intelligible varieties apart from Bardi: Baard and Jawi. The extent of dialect diversity within Bardi is unknown, but does not seem to have been particularly high compared to that between named varieties. The ISO-639 language code is [bcj].
