Note 9 — INTRODUCTION
Reading edition
In initial position there is no contrast between /ʔ/ and its absence, and phonetically the [ʔ] is always articulated. Intervocalically there is no contrast between successive like vowels and like vowels separated by a /ʔ/ (between [aa] and [aʔa]; [uu] and [uʔu]; [ii] and [iʔi]), and phonetically the [ʔ] is always present. Between unlike vowels there is either a [ʔ] or a [w] or [y] glide.
