Iqembu labacwaningi abavela e-Ben-Gurion University of the Negev kanye ne-Weizmann Institute of Science (Israel) lenze indlela () ukwakha kabusha ingxoxo yasendlini kanye nomculo kusetshenziswa ukuhlaziya kokudlidliza okunganyakazi kwesibani endaweni yokukhanya elengayo. Inzwa ye-electro-optical ebekwe emgwaqeni yayisetshenziswa njenge-analyzer futhi, kusetshenziswa isibonakude, yayihloselwe isibani esibonakala ngefasitela. Ukuhlolwa kwenziwa ngamalambu e-LED angu-12-watt futhi kwenza kwaba nokwenzeka ukuhlela ukulalela kusuka ebangeni elingamamitha angu-25.
Indlela isebenzela isibani esimisiwe. Ukudlidliza komsindo kudala umehluko kumfutho womoya, obangela ukunyakaziswa okuncane kwento emisiwe. Ama-microvibrations anjalo aholela ekuhlanekeni kokukhanya kuma-engeli ahlukene ngenxa yokugudluzwa kwendiza yokukhanya, okungatholwa kusetshenziswa inzwa ye-electro-optical ebucayi futhi yehliswe ibe umsindo. Kwasetshenziswa isibonakude ukuze kuthwebule ukuhamba kokukhanya futhi sikuqondise kunzwa. Isignali etholwe kunzwa (i-Thorlabs PDA100A2 esekelwe ku-photodiode) iguqulelwe kwifomu ledijithali kusetshenziswa i-16-bit analog-to-digital converter ADC NI-9223.
Ukuhlukaniswa kolwazi oluhlobene nomsindo kusuka kusignali evamile ye-optical kwenziwa ngezigaba eziningana, kuhlanganise , ukujwayela, ukunciphisa umsindo kanye nokulungiswa kwe-amplitude ngobuningi. Iskripthi se-MATLAB silungiselelwe ukucubungula isignali. Ikhwalithi yokubuyiselwa komsindo uma uthatha amapharamitha ukusuka ebangeni elingamamitha angu-25 ivele yanele ukubonwa kwenkulumo nge-Google Cloud Speech API kanye nokunquma ukuqanjwa komculo ngezinsizakalo ze-Shazam ne-SoundHound.
Esivivinyweni, umsindo uphinde wakhiqizwa ekamelweni ngevolumu ephezulu yezipikha ezitholakalayo, i.e. umsindo wawuphezulu kakhulu kunenkulumo evamile. Isibani se-LED asizange sikhethwe ngenhlanhla, kodwa njengoba sinikeza isilinganiso esiphezulu sesignali-kuya-nomsindo (izikhathi ezingu-6.3 ngaphezu kwesibani se-incandescent kanye nezikhathi ezingu-70 ngaphezu kwesibani se-fluorescent). Abacwaningi bachaze ukuthi ububanzi bokuhlasela nokuzwela kunganyuswa ngokusebenzisa isibonakude esikhulu, inzwa yekhwalithi ephezulu, kanye ne-24- noma 32-bit analog-to-digital converter (ADC); ukuhlolwa kwenziwa kusetshenziswa isibonakude esisebenzayo, inzwa eshibhile, kanye ne-16-bit ADC. .
Ngokungafani nendlela ehlongozwe ngaphambilini "", ethwebula futhi ihlaziye izinto ezidlidlizayo egumbini, njengengilazi yamanzi noma iphakethe le-chip, i-Lamphone yenza kube nokwenzeka ukuhlela ukulalela ngesikhathi sangempela, kanti umbhobho obonakalayo wokwakha kabusha imizuzwana yokukhuluma udinga izibalo ezithathayo. amahora . Ngokungafani nezindlela ezisekelwe ekusetshenzisweni noma njengemakrofoni, iLamphone ivumela ukuhlasela ukuthi kwenziwe ukude, ngaphandle kwesidingo sokusebenzisa uhlelo olungayilungele ikhompyutha kumadivayisi asemagcekeni. Ngokungafani nokuhlasela usebenzisa , I-Lamphone ayidingi ukukhanya kwento edlidlizayo futhi ingakhiqizwa ngemodi yokwenziwa.
