Nepali, a language of the Indo-Aryan family, is the official language of Nepal. According to the 2001 population census of Nepal, more than 11 million Nepalese (48.61% of the total population) claim this language as their mother tongue. It is also spoken in other countries of South Asia, such as India and Bhutan, as well as by members of the Nepalese Diaspora around the world. The population census of India of 1991 reported that more than two million Indians use Nepali as their mother tongue. Within Nepal, Nepali shows some dialectal variation mainly linked to geographical and socio-cultural factors. Nevertheless, the dialect called the ‘eastern’ dialect spoken by a majority of Nepali speakers shows rather little variation (Bandhu et al. 1971).

Palula is an Indo-Aryan language spoken by approximately 10,000 people in the southern part of Chitral District in Pakistan's North-West Frontier Province. It belongs to a group of speech varieties subsumed under the heading Shina (Morgenstierne 1941; Strand 2000–2001). The speech described here is that of Ashret Valley, one of two main dialects of Palula. The transcription is based on a recording of the speech of the second author, Naseem Haider, himself a native speaker of Palula, born in 1978; his speech is typical of Ashreti, or southern, Palula.

Mah Meri (ãʔ məri) belongs to the Aslian branch of Mon-Khmer within the Austroasiatic family. It is classified as a Southern Aslian language, along with Semelai, Semoq Beri and Temoq (Benjamin 1976). Mah Meri is spoken by the Mah Meri ethnic group in scattered settlements along the south-west coast of the Malay peninsula stretching from Port Kelang to Bukit Bangkong, Sepang in the state of Selangor, Malaysia. The island of Sumatra lies a short distance away across the Malacca Strait. The Mah Meri language, which may have as many as 2,185 speakers, has no written tradition and is highly endangered.

Mavea is spoken on the eponymous island, Mavea, a satellite island off the east coast of Espiritu Santo Island, northern Vanuatu. The language is highly endangered. There are about 34 fluent speakers on Mavea Island (aged 30 and older), out of a total island population of around 210. There are at least another 30 Mavea speakers who have left the island permanently. These speakers now live throughout Vanuatu, mainly on Espiritu Santo Island (in the villages of Deproma and Matevulu), Aore Island, and in Port Vila, the capital city of Vanuatu. All Mavea speakers are bilingual in Bislama, one of the official languages of Vanuatu.

Hakka Chinese is also known in China as Kejia dialect. The present study is based on phonetic data collected from native speakers of Hakka Chinese, male and female, aged between 18 and 22, during our field trips to Hakka-speaking Meixian County in the northeastern part of Guangdong Province in southeastern China in 2007. The speakers have lived all their life in Meijiang District of the county, speaking Meijiang variety which is considered representative of Meixian Hakka. The style of speech illustrated here is that typical of the educated younger generation and the recording is that of a 22-year-old male college student.

Dinka is a Western Nilotic language within the Nilo-Saharan family. There are over two million speakers (Gordon 2005). The Dinkas live along the banks of the White Nile and its tributaries in Southern Sudan. There are also communities elsewhere within Sudan, in particular in the capital Khartoum, and abroad. Cows play a key role in the Dinka economy, and also in the sociocultural system. Four major dialect areas are commonly distinguished: Padang, Rek, Agar, and Bor. The variety of Dinka represented here – Luanyjang or, as in Roettger & Roettger (1989), Luac – is part of the Rek dialect group. The term Luanyjang ‘Luac Dinka’ refers in the first place to a section within the Dinka ethnic group, and by extension also to their variety of the Dinka language. The main Luanyjang town is Wuncuei, located about 170 kilometers east of the city of Wau. Luanyjang has around 15000 speakers according to Ethnologue (Gordon 2005), although the current number is likely to be much higher.

The style of speech illustrated is that typical of the educated younger generation in Hong Kong. The recording is that of a 22-year-old female university student who has lived all her life in Hong Kong.

The following description of French is based on the speech of a young Parisian female speaker. Varieties of French have almost identical inventories; the main differences are to be found in the maintenance or loss of certain contrasts.

The following description of Hausa is based on the variety of the language spoken in Kano, Nigeria. The sample text is transcribed from a recording of a male native of Kano in his late 30's. This variety of Hausa is considered “standard”. Though Kano is a large urban center with some internal variation in speech, the sound inventory is relatively homogeneous within the city and surrounding area. Kano Hausa is the variety most commonly heard on national and regional radio and television broadcasts in Nigeria as well as most international broadcasting, such as the BBC, Deutsche Welle, Radio Moscow, and Voice of America. Kano Hausa is therefore familiar throughout the Hausa speaking areas of Nigeria as well as Hausa speaking communities in Niger, Ghana, and other areas outside northern Nigeria. Hausa has a standard orthography, in use since the 1930's and also based on the Kano variety. It is familiar to all Hausa speakers literate in the Romanized orthography. (Many Hausas are also literate in Arabic orthography, a variety of which has been used to write Hausa, probably for several centuries. The Arabic orthography for Hausa is less standardized than the Roman orthography and has little formally published literature.)
