Proto-Alri phonology
- Main article: Proto-Alri
This page gives an extensive description of Proto-Alri phonological features.
Consonants
The consonant system distinguishes 20 phonemes, traditionally arranged in the following scheme:
| plosive | voiceless | ||||||
| aspirated | |||||||
| pharyngeal | |||||||
| affricate | |||||||
| retroflex | |||||||
| nasal | |||||||
| liquid | |||||||
| fricative | sibilant | ||||||
| approximant | |||||||
The group of the plosive consonants distinguishes three sub-groups: voiceless, aspirated, and pharyngeal, even though the voiced sub-group includes only the phoneme [ʡ]. No plosive phoneme display a distinction in voicing.
The group of the nasal and of the liquid consonants is slighty poorer, but anyway quite developed. The presence of a developed group of a group of retroflex and affricate consonant is particularly noteworthy.
The group of the fricative consonant is remarkably scarce, with a single sibilant phoneme, [s]. The phonemes [j] and [w] can have both a semivocalic and a full consonantal value.
Vowels
There are 7 vocalic phonemes. No vowel makes any distinction neither in length nor in tone:
The vocalic system is typologically simple and essentially balanced, with the additional central phoneme, [ə].
