Wav2Letter Convolutional ASR
Wav2Letter ndeyekupedzisira-kusvika-kumagumo yekuziva matauriro sisitimu kubva kuFacebook AI yaingoshandisa convolutional neural network, hapana kudzokorora.
Pfupiso
It mattered as a fast, simple alternative that proved CNNs alone could transcribe speech competitively.
Kudzika Kwakadzika
Yakaunzwa neFacebook AI Tsvagiridzo muna 2016, Wav2Letter yakatyora kubva kune inodzokororwa uye HMM-yakavakirwa nzira nekutsamira chose pane convolutional neural network kumepu odhiyo zvakananga kune mavara (mavara), saka zita. Iyo yakatanga kudzidziswa neyakajairwa AutoSegCriterion (ASG) kurasikirwa, imwe nzira iri nyore kune yakajairika CTC kurasikirwa iyo yakadonhedza chiratidzo chisina chinhu uye yakateedzerwa tsamba shanduko zvakananga. Yakanyorwa muC++ ichishandisa Flashlight/ArrayFire backend, yakagadzirirwa kumhanya paPCU neGPU. Gare gare vhezheni, Wav2Letter++ uye iyo yakazara convolutional musiyano, yakayerwa kune yakakura dhataseti uye yakawana emakwikwi ekukanganisa mazwi mitengo paLibrispeech. Yayo convolution-chete dhizaini yakaita kuti ienzanise zvakanyanya uye inference-hushamwari kana ichienzaniswa neinotevedzana RNN decoder.
Technical Insight
Wav2Letter inorongedza 1D temporal convolutions pamusoro peacoustic features, nechikamu chega chega chichikudza nzvimbo yekugamuchira zvekuti stacks dzakadzika dzinotora kureba pasina kudzokorora. Nekuti convolutions inogadzira nguva dzese nhanho dzakafanana, kudzidziswa uye inference inokurumidza. Iko kurasikirwa kwekutanga kweASG kwakafanana neCTC asi kunobvisa chiratidzo chisina chinhu uye inowedzera pachena mavara-kune-tsamba ekuchinja zvibodzwa, ichigadzira iyo inonyatso patsanurika yekutevedzana dhizaini inoyananisa kusiyanisa-kureba odhiyo kune kubuda kwemavara pasina pa-frame mavara.
Strategic Impact
Svika uye svika
Inonatsiridza kusvikika kuburikidza nekunyora, kurondedzera, uye mazwi ekubatanidza.
Mutengo uye bhajeti
Zvikwata zveMedia zvinogona kutumira odhiyo yakakwenenzverwa nekukurumidza nemabhajeti madiki.
Kumhanya uye chiyero
Masisitimu anotarisana nevatengi anogona kugadzirisa kutaurirana kwekutaura pamwero mukuru.
Ramangwana reWav2Letter Convolutional ASR
Mutsara wakananga weWav2Letter unogara muTochi, Facebook's C++ muchina raibhurari yekudzidza, uye yakazivisa wav2vec yekuzvitarisira modhi idzo dzave kutonga. Chidzidzo chakafara, kuti convolution uye parallel architectures anogona kuenderana kudzokorora, kudyiswa zvakananga mu transformer-based ASR. Tarisira masisitimu emangwana kuti arambe achikwereta kumikidzo yeWav2Letter pane inoshanda, inofambirana, inosiyaniswa zvizere ekupedzisira-kusvika-kumagumo mapaipi uku uchiiswa pazvigadziro zvega zvekudzidzira mitauro isina zviwanikwa.
Real-World Implementation
Chaiyo-nguva yakanyorwa uko yakaderera-latency, yakafanana inference yakakosha kupfuura mashoma mapoinzi echokwadi.
Pa-mudziyo kana CPU-yakasungwa kutaura kucherechedzwa isingakwanise kutenga inorema inodzokororwa madhikodha
Tsvagiridzo yekutanga kuenzanisa convolutional ASR inopesana neRNN uye transformer masisitimu paLibrispeech
Kushanda senheyo yeinjiniya ye Facebook's Flashlight raibhurari uye gare gare wav2vec modhi
Njodzi & Guardrails
Kushandisa izwi zvisizvo uye njodzi dzekuedzesera dzinowedzera kana chibvumirano chisipo.
Kururama kunogona kudonha mumitauro, mataurirwo, kana nharaunda dzine ruzha.
Synthetic audio inogona kukanganisa kutaura kwechokwadi isina mavara akajeka.
Implementation Roadmap
Wana mvumo yakajeka yekutora inzwi, kugadzira, uye kushandisa zvakare.
Yedza mhando pavatauri vakasiyana uye mamiriro ekumashure.
Tsanangura apo munhu anofanira kuongorora kana kubvumidza zvabuda.
Label synthetic odhiyo uye chengetedza marekodhi ekuzvidavirira.

What is Wav2Letter Convolutional ASR?
Wav2Letter ndeyekupedzisira-kusvika-kumagumo yekuziva matauriro sisitimu kubva kuFacebook AI yaingoshandisa convolutional neural network, hapana kudzokorora. Zvaive nebasa sekukurumidza, imwe nzira yakapusa yakaratidza kuti CNNs chete yaigona kunyora kutaura nemakwikwi.
Ndeipi neural network architecture iyo Wav2Letter inovimba nayo chete?
Wav2Letter inozivikanwa nekushandisa chete convolutional neural network, kudzivirira kudzokorora zvachose.
Nderipi sangano rakatanga Wav2Letter?
Wav2Letter yakaunzwa neFacebook AI Tsvagiridzo muna 2016 uye yakazopinda muraibhurari yeTochi.
Ko 'tsamba' iri muWav2Letter inorevei?
Wav2Letter inomepu odhiyo waveform yakananga kune akatevedzana mavara (mavara), nzira yekupedzisira-yekupedzisira.
Ko yepakutanga AutoSegCriterion (ASG) kurasikirwa kwakasiyana sei kubva kune yakajairika CTC kurasikirwa?
ASG inodonhedza CTC's isina chinhu tokeni uye panzvimbo pacho inowedzera yakajeka shanduko mamakisi pakati pemavara ichiramba ichinyatsosiyaniswa.
Chii chakakosha chinoshanda mukana weWav2Letter's convolution-chete dhizaini?
Kusiyana nekutevedzana kweRNNs, convolutions inogona kuverengerwa mukufanana mukati menguva, ichiita kuti sisitimu ikurumidze uye ishande.
