Vowels are differentiated by length and voice. A vowel can be long or short and have either breathy voice, harsh voice or modal voice.
Monophthongs:

Essentially, that means that essentially, there are 108 different monophonic vowel pronunciations.
Diphthongs:

The diphthongs also carry either a modal voice, harsh voice or a breathy voice.
Somali is also tonal with three tones that indicate grammatical functions rather than lexical differences.
Example: ínan (boy) inán (girl) or daméer (male donkey) dameér (female donkey).
Tone is carried by the mora, rather than the vowel of a given syllable. Stress is attached to tone. High tone (´) carries strong stress with falling tone (ˆ) carrying low stress. The low tone (`) carries no stress.
There’s also a consonant sandhi that occurs where either assimilation or elision may occur. The elision process is highly unusual amongst any living language. For example, /lt/ changes to /ʃ/
Coalescense may also occur which would assimilate two words following sandhi rules. This mostly depends on the speed of speech or the individual speaker.
There is a vowel harmony rule, where it is organized into front-back groups. Sometimes the harmony may extend beyond a single word, creating a “Harmonic Group”
Intonation is an important prosodic tool and is unrelated to tone.
Despite these complexities, Somali is currently mostly written in a version of Latin that provides many ambiguities.
See basicaly what I mean guys is Arabic and Latin both fail to express Somali fully Only Osmanya script is fit for this.
