Esse padrao com contato aumentado, no caso desse falante com fissura, pode ser decorrente de padroes articulatorios estabelecidos no periodo de aprendizado da fala, quando a fissura de labio ainda estava aberta, o que dificultava a constricao bilabial, fazendo com que o falante buscasse outro local na cavidade oral para faze-lo.
Isto, por se esperar que tal fone nasal seja produzido adequadamente ja que nao se trata de consoante de pressao, ou se houver alteracao na producao, que seja decorrente de sequelas da cirurgia de labio, dificultando o contato bilabial, nao sendo o que ocorre nesse caso.
No fone [m] ha um contato amplo que se soma a constricao bilabial, no fone [n] houve maior contato da ponta da lingua com o palato, embora somente do lado esquerdo o que nao ocorreu no fone [[??]] em que o contato ocorreu com o dorso da lingua.
The positional bias found specifically for bilabials in initial syllables and non-labial sonorants in non-initial syllables provided additional precision to prior findings in Polynesian phonotactics.
And in C-C's, the positional bias for bilabials and coronal sonorants is an important factor in the frequency structure of homorganic consonant pairs.
Thus, while it is true that p-m (0.0) and m-p (.52) have much lower O/E's than t-n (.92) and n-t (.80), these cases differ in that, with the first pair, both orders put a bilabial in the shunned non-initial syllable, but for t-n the coronal sonorant appears in the preferred non-initial position.
Also, VOT can be used for the distinction of bilabials, dentals, alveolar and velars from one another.
It is found: 1) voiceless stops have short VOT, voiceless aspirated have long VOT, while voiced stops are pronounced with prevoicing 2) VOT of dental and alveolar is less than those of bilabial and velar stops; this supports Hardcastle's (1973) claim that faster the movement of the articulator, the shorter the VOT, as both dental and alveolar are articulated with the tip of the tongue.
Pahari has 12 oral stops articulated from four different places of articulation namely bilabial, dental, alveolar and velar.
It is from a bilabial shift of Edenic boer [to burn].
The results for VOT and closure duration are consistent with the well-documented relation across languages between VOT, closure duration, and place of articulation whereby VOT is shorter for bilabials than for velars, and alveolars have an intermediate value between the two (Maddieson 1997; Cho and Ladefoged 1999).
Chuxnaban Mixe has four stops in bilabial, alveolar, velar, and glottal position.
