This is the way we identify the native speakers😂. Like, "Badhaadhaan dhadhaa bitu dhaqe, dhagaa malee dhadhaan hin jiru nan jedhe haadhakoo/በዻዻን ዸዻ ቢቱ ዸቄ፤ ዸጋ መሌ ዸዻን ሂን ጅሩ ናን ጄዼ ሃዸኮ" Northern usually pronounce it as "በዳዳን ደዳ ቢቱ ደቅዬ፤ ደጋ መሌ ደዳን ሂን ጅሩ ጄዴ ሃደክዎ" AAs pronounces it as "በጣጣን ጠጣ ቢቱ ጠቄ፤ ጠጋ መሌ ጠጣን ሂን ጅሩ ናን ጄጤ ሃጠኮ"😝
