Résumé
It matters because for nearly a decade it was the go-to foundation for academic and industrial ASR work.
Plongeur bu xóot
Kaldi, mi génn ci 2011 te Daniel Povey moo ko jiite, ñu bind ko ci C++ ak rëset yuñ boole ci script bash ak Perl. Tabax na ci kaw gasoduc ASR bu yàgg bi: génne ci màndarga akustik (MFCCs wala filtrebanks), model son fonem ak Model Mixture Gaussian wala, ci ganaw, reso neuronal yu xóot, ba noppi boole model akustik, lexicon waxin, ak model làkk ci benn graphe buñ mëna seetee. Tanneefam ci xaralaam mooy jëfandikoo ay transducer yu am pondération (WFSTs) yu bawoo ci bibliothèque OpenFST ngir boole bépp balluwaayi xam-xam ci benn graphe decodage. Kaldi dafa yónnee ay 'rëset' ngir ay done yuñ miin lu ci melni Switchboard, Librispeech, ak Wall Street Journal, loolu tax gëstukat yi mëna génne ay resultaa yu bees. Nekk na royuwaay bi ñuy jëfandikoo ngir méngale sistem yu bees yi.

Xeetu HMM-DNN hybrid bu Kaldi, dañu ko wecci bu baax ci xeetu neuronal yu mujj ba ci njeexte, yuy méngale audio bi ak bind bi. Projet bi Daniel Povey topp, k2 (ak ecosystem Icefall ak Lhotse), dafay xalaat xalaati WFST yu Kaldi ci PyTorch ak ay otomat yu am àpp yuñ mëna wuutale.

What is Kaldi Speech Recognition Toolkit?
Kaldi jumtukaay la bu amul fayda, open-source moo nekkoon platform gëstu bi gëna am solo ngir tabax sistem yuy xàmmee kàddu. Dafa am solo ndax lu tollu ci fukki at ci ginaaw la nekkoon fundaasioŋ bi ñuy jaar ngir liggéey ASR ci daara yu kawe yi ak ci usine yi.
Ban làkku prograam lañu bind core Kaldi?
Kaldi core bi dañu ko bind ci C++ ngir mëna liggéey, ak script bash ak Perl yuy orkestre tàggat ak dekodaasu rëset yi.
Ban jumtukaayu math la Kaldi di jëfandikoo ngir boole model akustik bi, lexicon bi, ak modelu làkk wi ci benn graphe decodage?
Kaldi dafay boole WFST yi ci bibliotek OpenFST ci benn graf HCLG bu dekodeer bi di seet.
Kan mooy ki njëkka sos ak jiite projet Kaldi bi?
Daniel Povey moo jiite defar Kaldi, ñu njëkka génne ko ci 2011, ci ganaw ga mu tàmbali projet k2 bi ci topp.
Ci gasoduk Kaldi bu yàgg bi, lan lañu njëkka jëfandikoo ngir modele GMM yi (Modèlu njaxasu Gaussian)?
GMMs yi dañu wane ni akustik bi di doxee ci fonem yi balaa reso neuronal yu xóot yi di leen wecci ci sistem hybrid yi.
Lan mooy turu ecosystem bu bees bi lalu ci PyTorch ci Kaldi?
