Speech Prosody 2002
One of the three possible intonation patterns found in Glasgow English y/n questions end in mid pitch. An account of this contour with H% - relatively high pitch - though explanatorily adequate because of a semantic generalisation that groups most questions together, is descriptively inadequate because of the pitch height consistently reached, mid level, and not relatively high pitch. To achieve both explanatory and descriptive adequacy, I propose an analysis with downstep of the right boundary tone H, which would yield a unified account of these mid level endings. This proposal, then, means another possible phonetic implementation of H%.
