Rhinoglottophilia

In linguistics, rhinoglottophilia refers to the connection between laryngeal (glottal) and nasal articulations. The term was coined by James A. Matisoff in 1975.

There is a connection between the acoustic production of laryngeals and nasals, as can be seen from the antiformants both can produce when viewed via a spectrogram. This is because both sounds in a sense have branched resonators: in the production of nasal sound, both the oral cavity and the nasal cavity act as resonators. For laryngeals, the space below the glottis acts as a second resonator, which in turn can produce slight antiformants.
