David Hanak Abacwaningi abavela eNyuvesi yaseChina yaseZheijiang beze nento ethakazelisa kakhulu, okungukuthi abasizi abahlakaniphile kumakhalekhukhwini (kulokhu uSiri no-Alexa) bangahlaselwa ngendlela elula kakhulu ngaphandle kokuba umnikazi wedivayisi ehlaselwe abe nanoma yimuphi umqondo. Mayelana nakho. Ukuhlasela okuqondiswa yi-Ultrasound akuzwakali endlebeni yomuntu, kodwa imakrofoni edivayisini yakho iyakwazi ukukubona futhi, njengoba kuvela, ingayalwa ezimweni eziningi.
Kungaba njalo okuthakaselayo
Ondrej Holzman Le ndlela yokuhlasela ibizwa ngokuthi "i-DolphinAttack" futhi isebenza ngesimiso esilula kakhulu. Okokuqala, kuyadingeka ukuguqula imiyalo yezwi lomuntu ibe amaza e-ultrasonic (ibhendi engu-20hz nangaphezulu) bese uthumela le miyalo kudivayisi eqondiwe. Okudingekayo ukuze kudluliselwe umsindo ngempumelelo isipikha socingo esixhunywe ku-amplifier encane kanye ne-ultrasonic decoder. Ngenxa yombhobho ozwelayo kudivayisi ehlaselwe, imiyalo iyabonakala futhi ifoni/ithebhulethi iyithatha njengemiyalo yezwi yakudala yomnikazi wayo.
Njengengxenye yocwaningo, kwavela ukuthi ngokuyisisekelo bonke abasizi besifazane emakethe basabela kuleyo miyalo elungisiwe. Noma ngabe i-Siri, i-Alexa, i-Google Assistant noma i-Samsung S Voice. Idivayisi ehloliwe ayizange ibe nomthelela kumphumela wokuhlola. Ngakho-ke ukusabela kwabasizi kwatholwa kokubili ocingweni nakuthebhulethi noma kukhompuyutha. Ngokuqondile, ama-iPhones, ama-iPads, ama-MacBooks, i-Google Nexus 7, i-Amazon Echo kanye ne-Audi Q3 ihlolwe. Sekukonke, bekunamadivayisi ayi-16 nezinhlelo ezihlukene eziyi-7. Imiyalo ye-Ultrasound yabhaliswa yiwo wonke umuntu. Okuhle nakakhulu ukuthi imiyalo eguquliwe (futhi engezwakali endlebeni yomuntu) nayo yaqashelwa umsebenzi wokuqaphela inkulumo.
Kusetshenziswe izinqubo eziningana ekuhlolweni. Kusukela kumyalo olula wokudayela inombolo, ukuvula ikhasi elishiwo noma ukushintsha izilungiselelo ezithile. Njengengxenye yokuhlolwa, kwakwazi ngisho ukushintsha indawo lapho imoto yayihamba khona.
Okuwukuphela kwezindaba ezinhle ngale ndlela entsha yokugebenga idivayisi yiqiniso lokuthi okwamanje isebenza cishe kumamitha owodwa nesigamu kuya kwamabili. Ukuvikela kuzoba nzima, njengoba abathuthukisi bezwi abasizi bengeke bafune ukukhawulela amaza okuzwa imiyalo, njengoba lokhu kungaholela ekusebenzeni okubi kakhulu kwalo lonke uhlelo. Nokho, esikhathini esizayo kuyodingeka kutholakale ikhambi elithile.

Njengoba uhumusha lesi sihloko, ubungase usenze sicace kakhudlwana. Kusukela koqobo lwesiNgisi, ayidida kakhulu indlela esebenza ngayo. Ukuvikela kuyinto encane, vele ungayinaki imiyalo eza kuphela kumaza we-ultrasonic.
Yebo, futhi njengoba kushiwo esihlokweni, abathuthukisi ngeke baqhubeke nokushaya indiva imiyalo evela kumaza we-ultrasonic, njengoba akucaci kahle ukuthi lokhu kuzothinta kanjani ikhwalithi ewumphumela kanye namakhono okuqashelwa kwemiyalelo yezwi yakudala.
Cha, lesi sihloko sithi ukusika i-spectrum. Ngiphakamise ukunganaki okokufaka, okuhlanganiswe kuphela ingxenye ye-ultrasonic ye-spectrum.
