Its Listener is a pyramidal recurrent encoder; its Speller is an attention-based recurrent decoder. The original paper reports results for a specific Google voice-search subset and does not establish that LAS outperformed the compared production system.

The LAS paper defines two components: a Listener, a pyramidal recurrent encoder that accepts filter-bank spectra, and a Speller, an attention-based recurrent decoder that emits characters. The pyramidal encoder reduces sequence length, making attention over the encoded frames more manageable. The paper describes joint learning of recognizer components and reports that its model generated character sequences without a pronunciation dictionary or a separately trained language model. On a subset of Google voice search, it reports 14.1% WER without a language model and 10.3% with language-model rescoring; the compared CLDNN-HMM result was 8.0%. These historical numbers apply to the paper’s specific evaluation.
Dhaqangelinta Adduunka-dhabta ah
Use LAS as a historical example of an encoder-decoder recognizer that emits characters from acoustic input.
Inspect how the pyramidal Listener reduces the length of the encoder sequence.
Trace how attention connects each Speller output step to encoder states.
Compare reported WER only within the paper’s stated task and evaluation setup.
Mustaqbalka Dhageysiga xaadirka iyo Higgaadda
LAS is useful historically for understanding attention-based end-to-end ASR. Later systems explored different encoders, objectives, and streaming mechanisms; performance and latency must be compared on the same data and decoding conditions.

Maxay muhiim u tahay
- Helitaanka iyo gaarsiinta. Waxay wanaajisaa marin u helida iyada oo loo marayo qoraal-qorid, sheeko, iyo is-dhexgalyo cod.
- Qiimaha iyo miisaaniyada. Kooxaha warbaahintu waxay ku soo rari karaan codka sifaysan si degdeg ah iyagoo wata miisaaniyado yaryar.
- Xawaaraha iyo miisaanka. Nidaamyada u jeedda macmiisha waxay ka baaraandegi karaan isdhexgalka hadalka si weyn.
Iska ilaali
- Si xun u isticmaalka codka iyo khataraha is-yeelyeelku way kordhaan marka oggolaanshaha la waayo.
- Saxnimadu waxay hoos ugu dhici kartaa lahjadaha, lahjadaha, ama jawiga buuqa badan.
- Maqalka synthetic waxaa lagu khaldi karaa hadal dhab ah iyada oo aan si cad loo calaamadin.
Tallaabooyinka xiga
- Hel ogolaansho cad oo ku saabsan qabashada codka, xidhitaanka, iyo dib u isticmaalka
- Tijaabi tayada ku hadasha kala duwan iyo xaaladaha asalka.
- Qeex marka bani'aadamku ay tahay inuu dib u eego ama oggolaado wax soo saarka.
- Ku calaamadee codka synthetic oo xafid diiwaannada la-xisaabtanka.

Su'aalaha soo noqnoqda
What is Listen Attend and Spell?
Listen, Attend and Spell (LAS) is a 2015 end-to-end speech-recognition model that maps acoustic filter-bank features to character sequences. Its Listener is a pyramidal recurrent encoder; its Speller is an attention-based recurrent decoder. The original paper reports results for a specific Google voice-search subset and does not establish that LAS outperformed the compared production system.
Waa maxay labada qaybood ee ugu muhiimsan qaabka LAS?
LAS waxa ay ka kooban tahay codeeyaha 'Dhageystaha' kaas oo farsameeya maqalka iyo 'Speller' decoder-ku-salaysan oo soo saara jilayaasha.
Muxuu sameeyaa Higaada ku jirta LAS?
Higgaadiyaha waa furaha soo saara jilaha qoraalka, si toos ah u baranaya higgaadda.
Waa maxay sababta koodka LAS loogu yeedhay 'pyramidal'?
Lakab kasta oo ka mid ah pyramidal BLSTM wuxuu kala barayaa dhererka isku xigxiga, isagoo gaabinaya isku xigxiga maqalka dheer si taxadarku u noqdo mid macquul ah.
Waa maxay qaybta da'da weyn ee LAS gaar ahaan AANU u baahnayn?
Si ka duwan sida dhuumaha HMM-DNN ee caadiga ah, LAS waxay si toos ah wax uga barataa lammaane maqal-ilaa-qoraalka ah oo aan lahayn qaamuus foonme ah ama toosin qasab ah.
Farsamaynkee u ogolaanaya Higaada inuu diirada saaro qaybta ku habboon ee maqalka ee jile kasta?
Farsamaynta fiiro gaar ah waxay ku xisaabisaa miisaannada cod-bixiyayaasha, samaynta macnaha guud ee qalabka wax-qabaduhu isticmaalo tallaabo kasta.
