The prenasalized stops also occur in several branches of the Hmong–Mien language family of Southern China and Southeast Asia. In dialects of northern Japan, standard voiced stops are prenasalized, and voiceless stops are voiced. For example, "strawberry" is in most of the south, but in much of the north. Prenasalized stops are also reconstructed for Old Japanese. Europe In Greek the orthographic sequences μπ, ντ γκ and γγ are often pronounced as prenasalized voiced stops , , and , respectively, especially in formal speech and among older speakers. Among younger speakers the prenasalization often disappears and in fast speech the voiced stop may be replaced by a fricative. South America The Guaraní language has a set of prenasalized stops which are alternate allophonically with simple nasal continuants; they appear only within a word, to the left of a stressed vowel that is oral. South Asia The Indo-Aryan languages Sinhala and Dhivehi have prenasalized stops. Sinhala script has prenasalized versions of , /ʥ/, , and . Sri Lankan Malay has been in contact with Sinhala a long time and has also developed prenasalized stops. The spectrograms on the right show the word gaambar with a prenasalized stops and the word sambal with a sequence of nasal+voiced stop, yet not prenasalized. The difference in the length of the [m] part is clearly visible. The nasal in the prenasalized word is much shorter than the nasal in the other word. This phonetic information is complemented by phonological evidence: The first vowel in gaambar is lengthened, which only happens in open syllables in Sri Lanka Malay. The syllabification of gaambar must be gaa.mbar then, and the syllabification of sambal sam.bal. Oceania An example of the unitary behavior of prenasalized stops is provided by Fijian. In this language, as in many in Melanesia, there is a series of voiceless stops, , and a series of prenasalized stops, , but there are no simple voiced stops, . In addition, Fijian allows prenasalized stops at the beginning of a word, but it does not allow other consonant sequences. Thus the prenasalized stops behave like ordinary consonants. In some Oceanic languages, prenasalisation of voiced consonants depends on the environment. For example, in Raga, b and d are prenasalised when the preceding consonant is nasal (noⁿda "ours"), but not elsewhere (gida "us").
