Ingabe amakati angakhulumisana?
Context:Amakati adinga ukuxhumana ukuze akhe isibopho, futhi abe nobuhlobo nomunye nomunye; adinga ukusebenzisana, ukudlala, nokwabelana ngemithombo. Lapho zikhuluma nabantu, zikwenza ukuze zithole lokho ezikudingayo noma ezikufunayo, njengokudla, uthando noma ukudlala.  Amakati asebenzisa izindlela eziningi zokuxhumana ezinjengokukhuluma, ukubona, ukuthinta nokuhogela. Ngokuvamile amakati ayabhonga ukuze axhumane nabantu, kodwa kuyaqabukela enza kanjalo kwezinye izilwane. Ngenxa yalokho, izindlela zokuxhumana zamakati ziye zathinteka kakhulu ngenxa yokufuywa. Kuye kwacwaningwa imisindo ehlukahlukene yamakati engu - 21. Manje sekuyacaca ukuthi amakati asekhaya aqabula kakhulu kunamakati asendle.
Izwi lamakati liye lahlukaniswa ngezigaba ezihlukahlukene. Ekuqaleni kwasikiselwa uMildred Moelk, imisindo yamakati ivame ukuhlukaniswa ngezigaba ezintathu eziyinhloko:  imisindo ekhiqizwa umlomo uvaliwe (ukububula <unk> ukubhonga, ukuqhaqhazela) imisindo ekhiqizwa lapho umlomo uqala ukuvulwa bese uvalwa kancane kancane (ukukhala, ukukhala, ukukhala) imisindo ekhiqizwa umlomo uvuleke ngokuqinile endaweni efanayo (ukugquma, ukubhonga, ukuhlebeza, ukukhafula, ukuchachamba, nokukhala). Ngo-1944, uMoelk washicilela ucwaningo lokuqala lwamazwi amakati. Wayelalelisisa lapho amakati akhe ekhuluma futhi wahlela imisindo yawo yaba amaphethini angu-16 omshwana ahlukaniswe ngezigaba ezintathu eziyinhloko. Wasebenzisa nezinhlamvu zamagama ukuze abhale phansi imisindo ehlukahlukene. Wathi amakati ayenezinhlobo eziyisithupha ezahlukene zokumemeza ukuze amelele ubungane, ukuzethemba, ukunganeliseki, intukuthelo, ukwesaba nobuhlungu. UMoelk wahlukanisa eminye imisindo eyisishiyagalombili ehilelekile ekuzaleni nasekulweni ngokulalela izilwane egcekeni lakhe nasemgwaqweni.  Brown et al. bahlukanisa izimpendulo zezingoma zamakati ngokuya ngomongo wokuziphatha: ngesikhathi sokuhlukaniswa kwamatshwele namakati omama, ngesikhathi sokuncishwa ukudla, ngesikhathi sobuhlungu, ngaphambi noma ngesikhathi sokuziphatha okusongela noma kokuhlasela, njengokuphikisana ngendawo noma ukudla, ngesikhathi sokuhlangenwe nakho okubuhlungu noma okucindezelayo kakhulu, njengemijovo evamile yokuvimbela nokuncishwa kwamatshwele. Izingcingo ezingavamile eziqoshiwe ezivela kumakati amadala zifaka phakathi ukubhonga, izingcingo zokubingelela noma ukububula, izingxoxo ezinde zezwi phakathi kwamakati asemabhokisini ahlukene, izingcingo "zokukhungatheka" ngesikhathi sokuqeqeshwa noma ukunqanyulwa kwezimpendulo ezimisiwe.  UMiller wahlukanisa imisindo yaba izigaba ezinhlanu ngokwemisindo ekhiqizwayo: ukubhonga, ukubhonga, ukubiza, ukubhonga nokugquma.  U-Owens nabanye bahlukanisa amazwi amakati ngezigaba ngokuya ngesakhiwo sawo se-acoustic. Kunezigaba ezintathu: imisindo enama-tonal, imisindo enama-pulse, nemisindo enama-broadband. Imisindo ye-tonal ihlukaniswa futhi ngamaqembu emisindo eyakhiwe ngokuvumelanayo noma imisindo ye-tonal ejwayelekile. Izwi lokushaya kwenhliziyo lihlukaniswa libe yi-pulse bursts kanye ne-hybrid pulse bursts eneziphelo ezinesigqi. Imisindo ye-broadband ihlukaniswe ngamaqembu amane: imisindo ye-broadband engeyona i-tonal, imisindo ye-broadband eneziqalo ze-tonal, imisindo ye-broadband enezinto ezimfushane ze-tonal, nemisindo ye-broadband eneziphelo ezinde ze-tonal.
