David Hanak Ofufuza ochokera ku yunivesite ya China ya Zheijiang apeza chinthu chochititsa chidwi kwambiri, chomwe ndi chakuti othandizira anzeru m'mafoni am'manja (pankhaniyi Siri ndi Alexa) akhoza kuukiridwa m'njira yosavuta kwambiri popanda mwiniwake wa chipangizocho kukhala ndi lingaliro lililonse la izo. Kuwukira motsogozedwa ndi Ultrasound sikumveka m'makutu a munthu, koma maikolofoni mu chipangizo chanu amatha kuwazindikira ndipo, monga momwe zimakhalira, amatha kulamulidwa nthawi zambiri.
Izo zikhoza kukhala chidwi inu
Ondrej Holzman Njira yowukirayi imatchedwa "DolphinAttack" ndipo imagwira ntchito pa mfundo yosavuta kwambiri. Choyamba, ndikofunikira kutembenuza mawu amawu amunthu kukhala ma ultrasonic frequency (gulu 20hz ndi kupitilira apo) ndiyeno tumizani malamulowa ku chipangizo chomwe mukufuna. Zomwe zimafunikira pakufalitsa bwino kwamawu ndi choyankhulira cha foni cholumikizidwa ndi amplifier yaying'ono ndi ultrasonic decoder. Chifukwa cha maikolofoni tcheru mu chipangizo chowukiridwa, malamulowa amadziwika ndipo foni / piritsi imawatenga ngati malamulo apamwamba a eni ake.
Monga gawo la kafukufukuyu, zidapezeka kuti makamaka othandizira azimayi pamsika amayankha malamulo osinthidwa otere. Kaya ndi Siri, Alexa, Google Assistant kapena Samsung S Voice. Chipangizo chomwe chinayesedwa chinalibe mphamvu pa zotsatira zoyesa. Chifukwa chake zomwe othandizira adalandira kuchokera pafoni komanso kuchokera pa tabuleti kapena kompyuta. Makamaka, ma iPhones, iPads, MacBooks, Google Nexus 7, Amazon Echo komanso Audi Q3 adayesedwa. Pazonse, panali zida 16 ndi machitidwe 7 osiyanasiyana. Malamulo a Ultrasound adalembetsedwa ndi aliyense. Chomwe chimakhala chowopsa kwambiri ndichakuti malamulo osinthidwa (komanso osamveka ku khutu la munthu) adazindikirikanso ndi ntchito yozindikira mawu.
Njira zingapo zidagwiritsidwa ntchito poyesa. Kuchokera pa lamulo losavuta kuyimba nambala, kutsegula tsamba lolembedwa kapena kusintha makonda ena. Monga gawo la mayesowo, zinali zotheka kusintha komwe galimotoyo imayendera.
Nkhani yabwino yokha ya njira yatsopano yozembera chipangizocho ndikuti imagwira ntchito pafupifupi mita imodzi ndi theka kapena iwiri. Chitetezo chidzakhala chovuta, monga opanga othandizira mawu sangafune kuchepetsa mafupipafupi a malamulo omwe akumva, chifukwa izi zingayambitse ntchito yoipitsitsa ya dongosolo lonse. Komabe, m'tsogolomu padzafunika kupeza njira yothetsera vutoli.

Popeza mukumasulira nkhaniyi, mukanapangitsa kuti ikhale yomveka bwino. Kuchokera ku Chingelezi choyambirira, ndizosasokoneza momwe zimagwirira ntchito. Chitetezo ndichaching'ono, ingonyalanyazani malamulo omwe amabwera kokha pa ultrasonic frequency.
Inde, ndipo monga tafotokozera m'nkhaniyi, opanga sangapitirize kunyalanyaza malamulo ochokera kumayendedwe a ultrasonic, chifukwa sizikudziwika bwino momwe izi zingakhudzire zotsatira za khalidwe ndi kuzindikira kwa malamulo apamwamba a mawu.
Ayi, nkhaniyo ikuti chepetsani mawonekedwe. Ine akufuna kunyalanyaza athandizira, amene wapangidwa yekha akupanga mbali ya sipekitiramu.
