Vatsvagiri kubva kuYunivhesiti yeMichigan uye Osaka University nzira itsva yekurwisa , zvichikubvumidza kuti utevedzere kure mirairo yezwi uchishandisa laser yezvishandiso zvinotsigira kutonga kwezwi, senge vatauri vakangwara, mahwendefa, smartphones uye smart home control system uchishandisa Google Assistant, Amazon Alexa, Facebook Portal uye Apple Siri. Munguva yezviyedzo, kurwiswa kwakaratidzwa kwakaita kuti zvibvirire kutsiva izwi rekuraira kubva kure nemamita makumi manomwe neshanu kuburikidza negirazi rehwindo uye 75 metres munzvimbo yakavhurika.
Kurwiswa kunobva pakushandiswa , umo kutorwa kwekuchinja (modulated) chiedza nechinhu kunotungamirira mukupisa kwekupisa kwepakati, kuchinja kwehuwandu hwezvinhu uye kuonekwa kwemafungu ezwi anonzwisiswa ne microphone membrane. Nekugadzirisa simba relaser uye kutarisisa danda pagomba nemaikorofoni, unogona kuwana kurudziro yekurira kwemazwi ayo asinganzwike kune vamwe, asi anozoonekwa nemakrofoni.
Kurwiswa uku kunokanganisa maikorofoni emagetsi anoshandiswa mumidziyo yemazuva ano ().
Pakati pezvishandiso zvevatengi zvakaedzwa kuti zvionekwe nedambudziko pane akasiyana mhando dzeGoogle Home, Google NEST, Amazon Echo, Echo Plus/Spot/Dot, Facebook Portal Mini, Fire Cube TV, EchoBee 4, iPhone XR, iPad 6th Gen, Samsung Galaxy. S9 neGoogle Pixel 2, zvakare akangwara makiyi uye manzwi ekudzora masisitimu eTesla neFord mota. Uchishandisa nzira yekurwisa yakarongwa, unogona kutevedzera kuburitsa murairo wekuvhura gonhi regaraji, kutenga pamhepo, edza kufungidzira PIN kodhi yekuwana kiyi yakangwara, kana kutanga mota inotsigira kudzora inzwi.
Muzviitiko zvakawanda, laser simba ye50 mW inokwana kuita kurwisa kure neanopfuura makumi mashanu. Kuita kurwisa uku, pakashandiswa laser pointer ye$60- $14, mutyairi welaser weWavelength LD18CHA wemadhora mazana matatu nemakumi matatu, Neoteck NTK5 audio amplifier, $339 Opteka 059-28mm telephoto lens. Kunyatso kutarisisa danda kure kure nemudziyo, vaedzi vakashandisa teresikopu sekuona kwemaziso. Panzvimbo dzepedyo, panzvimbo yelaser, isina kujeka inopenya inopenya sosi, senge .
Kurwiswa kazhinji hakudi kuyedzerwa kweizwi remuridzi, nekuti kuzivikanwa kwezwi kunowanzo shandiswa padanho rekuwana mudziyo (kusimbisa nekutaura "OK Google" kana "Alexa", iyo inogona kurekodhwa pachine nguva uye yozoshandiswa kuenzanisa. chiratidzo panguva yekurwisa). Hunhu hwezwi hunogona zvakare kunyengedzwa neazvino muchina kudzidza-yakavakirwa kutaura synthesis maturusi. Kuti vadzivise kurwiswa, vagadziri vanokurudzirwa kushandisa mamwe machani echokwadi evashandisi, shandisa data kubva kumakrofoni maviri, kana kuisa chipingamupinyi pamberi pemaikorofoni inovhara nzira yakananga yechiedza.
