Njengengxenye ebalulekile yesayensi nobuchwepheshe besimanje, inzwa isetshenziswa kabanzi. Kusukela ezishintshayo zezimboni kuya ezindlini ezihlakaniphile, kusukela ekunakekelweni kwezempilo kuya ekuvikelweni kwemvelo, izinzwa zidlala indima ebalulekile. Bangakwazi ukuzwa futhi balinganise amanani ahlukahlukene omzimba, njengezinga lokushisa, ukucindezela, ukukhanya, umsindo, njll., futhi baguqule lolu lwazi lube amasignali kagesi angacutshungulwa futhi adluliselwe. Leli khono lokuguqula lenza izinzwa zibe ibhuloho phakathi kwezwe eliphathekayo neledijithali, linikeze okokufaka kwedatha okudingekayo kumasistimu namadivayisi ahlakaniphile ahlukahlukene. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ukunemba, ukuzinza nokuthembeka kwezinzwa nakho kuyathuthuka, kunikeze ithuba lohlu olubanzi lwezimo zohlelo lokusebenza.
