Only in ARCHI 72
What this means for learners
ARCHI and Amharic share 19 sounds — roughly 21% of Amharic's inventory overlaps with ARCHI. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 49 sounds found only in Amharic represent the greatest pronunciation challenge for ARCHI speakers. The adult brain tends to map unfamiliar sounds onto the closest native equivalent — a process that produces the characteristic "accent" of a second-language speaker. Learning to hear and produce these sounds as distinct requires focused ear training, not just repetition.
Conversely, ARCHI has 72 sounds not used in Amharic. Native Amharic speakers learning ARCHI will face the mirror-image challenge with these sounds.
