I-Source-Filter Vocoding kanye ne-WORLD
Ivokhoda iyithuluzi elihlukanisa inkulumo liyihlukanise libe ngamabhulokhi wokwakha futhi liyakhe kabusha.
Uhlolojikelele
The source-filter model and the WORLD vocoder are classic methods that power text-to-speech and voice conversion by separating what your vocal cords do from what your mouth shapes.
I-Deep Dive
Imodeli yesihlungi somthombo ichaza inkulumo njengezingcezu ezimbili ezisebenza ndawonye: umthombo (umsindo ovela ezintanjeni zephimbo ezivevezelayo zemisindo ephinyisiweyo, noma umoya onomsindo wokunyenyeza nongwaqa) udlule kusihlungi (umumo ozwakalayo womphimbo wakho, umlomo, nekhala). Ivokhoda ihlaziya umsindo orekhodiwe ukuze ilinganisele lezi zingcezu, bese ihlanganisa umsindo omusha kuzo. I-WORLD, ekhishwe nguMasanori Morise cishe ngo-2016, iyi-vocoder yekhwalithi ephezulu ekhipha imingcele emithathu: F0 (i-pitch contour yomthombo), imvilophu ye-spectral (isihlungi, nge-algorithm yayo ye-CheapTrick), kanye ne-aperiodicity (umsindo ongakanani ngokumelene nethoni, nge-PLATINUM/D4C). Lokhu kusakazwa okuthathu kungalungiswa ngokuzimela bese kuhlanganiswe kabusha, okwenza UMHLABA ube yizisulu ze-TTS yepharamitha kanye nezinhlelo zezwi eziculayo.
I-Technical Insight
Amandla omhlaba atholakala ngokuhlukana okuhlanzekile. I-CheapTrick ilinganisela imvilophu ye-spectral ebushelelezi enamandla kumaphutha amancane we-F0, kuyilapho i-DIO/Harvest track pitch kanye ne-D4C ikala i-band aperiodicity. Ngenxa yokuthi iphimbo, i-timbre, nomsindo kuhlala emifudlaneni ehlukene yepharamitha, ungakwazi ukuhambisa u-F0 uye phezulu kwe-octave ngaphandle kokushintsha ukuthi izwi lizwakala kanjani, noma ukwelula ubude besikhathi ngaphandle kokushintsha iphimbo. Ama-Neural vocoder afana ne-WaveNet kamuva amodela i-waveform ngokuqondile, kodwa UMHLABA uhlala ushesha, utolika, futhi ungenalo ilayisense.
I-Strategic Impact
Finyelela futhi ufinyelele
Ithuthukisa ukufinyeleleka ngokuloba, ukulandisa, nezixhumi ezibonakalayo zezwi.
Izindleko kanye nesabelomali
Amaqembu emidiya angathumela umsindo opholishiwe ngokushesha ngamabhajethi amancane.
Isivinini nesikali
Amasistimu abhekene nekhasimende angacubungula ukusebenzelana okukhulunyiwe ngesilinganiso esikhulu.
Ikusasa Lokukhuluma Kwezwi Lomthombo-Okuhlunga kanye NOMHLABA
Amavokhoda ahlanzekile acutshungulwa amasignali athathwe kakhulu ngama-neural vocoder (HiFi-GAN, WaveRNN) ukuze abe ngokwemvelo ekugcineni, kodwa UMHLABA awukanyamalala. Iphila njengesiphelo sangaphambili esisheshayo, esivumelana ne-CPU ngaphakathi kwamapayipi okuguqula izwi, ama-synthesizers aculayo, nezisekelo zocwaningo, nezici zayo zemvilophu engu-F0-plus-spectral-zisezondla amamodeli amaningi emizwa. Lindela amasistimu ayingxube lapho amapharamitha ahumusekayo esitayela SOMHLABA WONKE eqondisa amadekhoda e-neural, enikeza abadali ukulawula okunembile phezu kwephimbo ne-timbre ngaphandle kokudela amaqiniso.
Ukuqaliswa Komhlaba Wangempela
Amathuluzi okuguqula izwi ashintsha ukuphakama kwesipikha ne-timbre kuyilapho egcina inkulumo izwakala
Ama-synthesizers aculayo (njenge-UTAU/NNSVS ecosystem) ahlanganisa kabusha amanothi ezindaweni ezintsha
Amasistimu we-Parametric text-to-speech akhiqiza ukusakazwa kwe-F0, spectral, kanye ne-aperiodicity ngaphambi kwezwi
Izisekelo zocwaningo lwenkulumo zokushintsha kwephimbo, ukwelula isikhathi, nokuhlelwa kwe-prosody ngaphandle kokuqeqeshwa kabusha
Izingozi & Guardrails
Ukusetshenziswa kabi kwezwi kanye nezingozi zokuzenza ongeyena ziyanda uma imvume ingekho.
Ukunemba kungase kwehle kuzo zonke izinhlobo zokuphimisela, izilimi zesigodi, noma izindawo ezinomsindo.
Umsindo wokwenziwa ungenziwa iphutha njengenkulumo eyiqiniso ngaphandle kokulebula okucacile.
Ukuqalisa Umhlahlandlela
Thola imvume esobala yokuthwebula izwi, ukuhlanganisa, nokusebenzisa kabusha.
Ikhwalithi yokuhlola kuzo zonke izipikha nezimo zangemuva.
Chaza ukuthi kunini lapho umuntu kufanele abuyekeze noma agunyaze okuphumayo.
Lebula umsindo wokwenziwa futhi ugcine amarekhodi atholakalayo ukuze aziphendulele.

Imibuzo evame ukubuzwa
What is Source-Filter Vocoding and WORLD?
Ivokhoda iyithuluzi elihlukanisa inkulumo liyihlukanise libe ngamabhulokhi wokwakha futhi liyakhe kabusha. Imodeli yesihlungi somthombo kanye nevokhoda YOMHLABA izindlela zakudala ezinikeza amandla ukuguqulwa kombhalo uye enkulumweni kanye nezwi ngokuhlukanisa lokho okwenziwa yizintambo zakho kulokho okwenziwa ngumlomo wakho.
Kumodeli yenkulumo yesihlungi somthombo, 'isihlungi' simeleni?
Isisefo siwukuzwakala kwephimbo — umumo womphimbo, umlomo, nekhala ombala umsindo. Umthombo umsindo wezwi noma ukugeleza komoya okunomsindo.
Yimaphi amapharamitha amathathu iVokhoda YOMHLABA ewakhipha enkulumeni?
UMHLABA ubolisa inkulumo ibe yimvamisa eyisisekelo (F0), imvilophu ye-spectral (i-timbre/isihlungi), kanye ne-aperiodicity (umsindo uma uqhathaniswa nebhalansi yethoni).
Lithini igama le-algorithm ye-WORLD yokulinganisa imvilophu ye-spectral?
I-CheapTrick ilinganisela imvilophu ye-spectral ebushelelezi enamandla kumaphutha amancane esilinganisweni somsindo.
Kungani kuwusizo ukuhlukanisa i-pitch kusuka kumvilophu ye-spectral?
Ngoba iphimbo (F0) kanye ne-timbre (imvilophu ye-spectral) kungukusakazwa okuzimele, ungakwazi ukuphakamisa noma ukwehlisa iphimbo ngenkathi ulondoloza ubunikazi besipikha.
UMHLABA uqhathaniswa kanjani namavokhoda e-neural afana ne-HiFi-GAN?
I-WORLD iyivowuda yokucubungula isignali: iyashesha, iyatolika, futhi inobungani be-CPU. Ama-Neural vocoder ngokuvamile afinyelela izinga eliphezulu lemvelo kodwa asindayo.
