Inkulumo inokuphatha okungaphezu kwamagama. Ukudakwa wutshwala kushiya imikhondo ekalekayo ekukhulumeni, isivinini, kanye nokwehluka okuncane kwesibonakaliso — izimpawu indlebe yomuntu ezibhalisa ngokungathembeki ngesimo esingcono kakhulu.
Ithimba le-R&D ye-XENOM liqeqeshe imodeli yokufunda ejulile eyakhelwe ngaphakathi ukuthola lawa ma-acoustic biomarker futhi layihlola ku-Alcohol Language Corpus, ibhentshimaki yomphakathi ejwayelekile yalomsebenzi.
Kutholwe ngokuqhathanisa ngokuqondile — isilinganiso sokukhumbula esingalinganisiwe ngewindi ngalinye, isinqumo esisodwa ngokukhuluma ngakunye ngaphandle kokuvota, ngendlela umsebenzi wangaphambili olinganiswa ngayo — ukucushwa okusekelwe kunkomba kufinyelela ku-86.3% UAR. Ukucushwa okungenankomba, okungadingi umugqa wesisekelo obhalisiwe futhi okunquma kusuka kusampula eyodwa ekhulunywayo, kufinyelela ku-81.9%. Endaweni yokusebenza yokukhishwa, lapho isistimu ihlanganisa amawindi amaningana okuqoshwa abe yisinqumo sokuvumelana, lawa akhuphukela ku-87.6% no-82.5% ngokulandelana.
Ukuze siqonde: umugqa wesisekelo osemthethweni we-Interspeech 2011 Speaker-State Challenge kule corpus umi ku-65.9% UAR, imiphumela yangaphambilini eshicilelwe yezinga eliphezulu ifinyelela cishe ku-73–75%, futhi abalalele abantu abangaqeqeshiwe bathola cishe ku-60–65%.
Isistimu isebenza njengengqimba engasebenziyo phezu kwethrafikhi yomsakazo ejwayelekile. Abasebenzi bakhuluma njengoba behlala benza; ayikho inqubo eyengeziwe, akukho kuphazamiseka emsebenzini, akukho indawo yokuhlola ehlukile.
Lokho isistimu eyikho — nengakona. Ayilinganisi izinga lotshwala egazini futhi ayikwazi ukusebenza njengesizathu sokususa isisebenzi emsebenzini. Iyithuluzi lokuhlola lezinga lokuqala elibonisa ukuthi ubani ofanele ukunakwa, ukuze kuqinisekiswe ngezindlela ezisunguliwe. Ukuqhathanisa okufanele akukona ne-breathalyzer, kodwa ngenye indlela esetshenziswa namuhla: ukubhekwa komphathi, okusebenza cishe ezingeni lokulalela okungaqeqeshiwe.
Sishicilele imiphumela egcwele kuzo zonke izimo ze-acoustic — kuhlanganise nalezo lapho ukunemba kwehla khona — kanye nezixwayiso zokuqhathanisa kanye nemikhawulo eyaziwayo yendlela.
