Mawu amanyamula zambiri osati mawu chabe. Kuledzera kumaonekera m'matchulidwe, liwiro, ndi kusintha kwakung'ono kwa mawu - zizindikiro zomwe khutu la munthu sizimazindikira bwino.
Gulu la R&D la XENOM laphunzitsa chitsanzo chakuya chodziwira zizindikiro izi ndipo adachiyesa pa Alcohol Language Corpus, muyezo wamba wa ntchito imeneyi.
Kuyesedwa mofanana ndendende — per-window unweighted average recall, chisankho chimodzi pa mawu aliwonse popanda kuvota, ndendende momwe ntchito zam'mbuyomu zimayesedwera — kusintha kwa reference-based kumafika pa 86.3% UAR. Kusintha kwa reference-free, komwe sikumafuna choyambira cholembedwa ndipo kumaganizira kuchokera pa chitsanzo chimodzi cholankhulidwa, kumafika pa 81.9%. Pa nthawi yogwiritsa ntchito, pomwe dongosolo limaphatikiza mawindo angapo a kujambula kukhala chisankho chogwirizana, izi zimakwera kufika 87.6% ndi 82.5% motsatana.
Kuti mumve bwino: maziko ovomerezeka a Interspeech 2011 Speaker-State Challenge pa corpus iyi ali pa 65.9% UAR, zotsatira zomwe zidasindikizidwa kale zapamwamba zimafika pafupifupi 73-75%, ndipo omvera osaphunzitsidwa amapeza pafupifupi 60-65%.
Dongosololi limagwira ntchito monga gawo lopanda kanthu pa mawayilesi anthawi zonse. Ogwira ntchito amalankhula monga momwe amachitira nthawi zonse; palibe ndondomeko yowonjezera, palibe kusokoneza ntchito, palibe malo ena ochezera.
Zomwe dongosololi limachita — ndi zomwe silimachita. Silimayeza kuchuluka kwa mowa m'magazi ndipo silingakhale chifukwa chochotsera wogwira ntchito. Ndi chida choyambirira chowonetsa yemwe akuyenera kuyang'aniridwa, kuti atsimikizidwe ndi njira zokhazikitsidwa. Kufanizira koyenera sikuli ndi breathalyzer, koma ndi njira ina yomwe imagwiritsidwa ntchito lero: kuyang'ana kwa woyang'anira, komwe kumachita pafupifupi monga kumvetsera kosaphunzitsidwa.
Tasindikiza zotsatira zonse pamikhalidwe yamawu — kuphatikiza pomwe kulondola kumachepa — pamodzi ndi machenjezo ofanizira ndi malire odziwika a njirayi.
