Overview
Kaldi ndeye yemahara, yakavhurika-sosi yekushandisa iyo yakave inotungamira yekutsvagisa chikuva chekuvaka masisitimu ekuzivikanwa kwekutaura. Izvo zvine basa nekuti kweanoda kusvika makore gumi yaive yekuenda-kunheyo yebasa redzidzo uye maindasitiri ASR.
Kaldi Speech Recognition Toolkit inogara muodhiyo-AI workflows inoshandura kutaura, mimhanzi, uye ruzha rwekutaurirana, kuwanikwa, uye kugadzirwa kwenhau.
Deep Dive
Kaldi, yakaburitswa muna 2011 uye ichitungamirwa naDaniel Povey, yakanyorwa muC ++ ine mabikirwo akabatanidzwa ne bash uye Perl zvinyorwa. Iyo yakavakirwa pane yekare ASR pombi: bvisa acoustic maficha (MFCCs kana mafirita mabhengi), modhi fonimu inonzwika neGaussian Musanganiswa Models kana, gare gare, yakadzika neural network, uye sanganisa acoustic modhi, mataurirwo lexicon, uye mutauro modhi mune imwechete yekutsvaga girafu. Sarudzo yaro yekutsanangura tekinoroji yaive kushandisa huremu hwekupedzisira-nyika transducer (WFSTs) kubva muraibhurari yeOpenFST kugadzira zvinyorwa zvese zveruzivo kuita girafu rimwe rekudhirodha. Kaldi akatumira 'mabikirwo' emadataseti akajairwa seSwitchboard, Librispeech, uye Wall Street Journal, zvichiita kuti vaongorori vaburitse mhedzisiro yemazuva ano. Yakave iyo yereferensi yekushandisa iyo masisitimu matsva akaiswa mabhenji.
Technical Insight
Kaldi's core trick kuumba maWFST ina mugirafu rimwe rinonzi HCLG: H mepu neural-net kana GMM inoti kune mafoni anoenderana nemamiriro ezvinhu, C inobata fonetiki mamiriro (matriphone), L ndiyo mataurirwo efononi yekumepu mafoni kumazwi, uye G ndiyo modhi yemutauro. Kuwanza aya matransducer uye nekunatsiridza mhedzisiro inoburitsa girafu imwe chete iyo decoder inotsvaga ine danda-yakatemwa Viterbi algorithm, ichishandura maodhiyo mafuremu kuita ingangoita izwi kutevedzana zvinobudirira.
Kudzidza Kaldi Kutaura Kuzivikanwa Toolkit
Kaldi ndeye yemahara, yakavhurika-sosi yekushandisa iyo yakave inotungamira yekutsvagisa chikuva chekuvaka masisitimu ekuzivikanwa kwekutaura. Izvo zvine basa nekuti kweanoda kusvika makore gumi yaive yekuenda-kunheyo yebasa redzidzo uye maindasitiri ASR. Kaldi Speech Recognition Toolkit inogara muodhiyo-AI workflows inoshandura kutaura, mimhanzi, uye ruzha rwekutaurirana, kuwanikwa, uye kugadzirwa kwenhau. Kuti uvake kunzwisisa kwakadzama, bata Kaldi Speech Recognition Toolkit semuenzaniso wekushandisa, kwete chinhu chimwe chete: tsanangura zvinodiwa, kujekesa fungidziro, uye patsanura zvinogona kuitwa nehurongwa hwakavimbika kubva kune zvichiri kuda kutonga kwenyanzvi.
Mukuita, zvikwata zvakasimba zvinoshandisa Kaldi Speech Recognition Toolkit zvinobata mhando, latency, uye mvumo sezvikamu zvakakosha zvakaenzana zvehurongwa hwekuendesa. Ivo vanonyora zvakajeka maitiro ebudiriro, bvunzo vachipokana ne data rechokwadi uye mafambiro ebasa, uye iterate zvichibva pane zvakacherechedzwa maitiro ekutadza kwete kuhwina-nguva imwe chete yebhenji. Apa ndipo apo kunzwisisa kwe theoretical kunoshanduka kuve kugona kwakasimba pane chigadzirwa, mutemo, uye mashandiro.
Inonatsiridza kusvikika kuburikidza nekunyora, kurondedzera, uye mazwi ekubatanidza. Panguva imwecheteyo, kusashandiswa kweIzwi zvisizvo uye njodzi dzekuedzesera dzinowedzera kana chibvumirano chisipo. Nzira yakatsiga ndeyekubatanidza kukurumidza kuyedza nekutonga: mhanyisa vatyairi vendege, tora humbowo, buritsa matanda esarudzo, uye urambe uchivandudza chengetedzo semaitiro emuenzaniso, zvinotarisirwa nemushandisi, uye zvinodikanwa zvekutonga.
