Acoustic Echo Cancellation Quiz

Ongorora mashandisiro anoita echo mareferenzi ekure-end referensi, mafirita anochinja, uye neural residual kudzvinyirira panguva yekufona uye kuchinja mamiriro ekamuri.

Mhinduro uye tsananguro zvinoonekwa paunenge uchitora bvunzo.

  1. Nderipi dambudziko iro acoustic echo kudzima kunonyanya kugadzirisa?
    • Kumisa ruzha rwemutauri kuti risasimudzwe nemaikorofoni uye kudzorerwa kure kure
    • Kudzvanya mafaira ekuteerera kuchengetedza bandwidth
    • Kuturikira kutaura kune mumwe mutauro
    • Kuwedzera ruzha rwevatauri vakanyarara
  2. Ndeipi 'referensi' chiratidzo icho AEC system inovimba nayo kufanotaura echo?
    • Maikorofoni yemutauri ari pedyo-kumagumo
    • Chiratidzo chekure-kure chiri kuridzwa kunze kwemutauri
    • A pre-recorded room template
    • Background ruzha mwero
  3. Ndeipi mamiriro ezvinhu anozivikanwa zvakanyanya kuomera AEC uye anogona kukonzera adaptive sefa kuita zvisizvo?
    • Kunyarara kwakakwana kumativi ose maviri
    • Munhu mumwechete achitaura zvishoma nezvishoma
    • Hurukuro-kaviri, kana mapato ese ari maviri achitaura panguva imwe chete
    • Kuridza mimhanzi pasina anotaura
  4. Iyo inogadzirisa sefa mune yekirasi AEC inoedza kufungidzira chii?
    • Manzwiro emutauriri
    • Simba rechiratidzo cheWi-Fi
    • Iyo compression codec iri kushandiswa
    • Iyo acoustic nzira (impulse mhinduro) kubva kumutauri kuenda kumakrofoni mukamuri
  5. Nei neural network ichiwedzera kuwedzerwa pamusoro pe classical AEC mafirita?
    • Kubata kukanganiswa kusiri mutsara uye kusara maungira ayo mutsara mafirita anopotsa
    • Kuita kufona kunodhura
    • Kutsiva maikorofoni hardware
    • Kunonotsa kugadziridzwa kwechokwadi
  6. Ndeipi adaptive algorithm inowanzobatanidzwa neyechinyakare echo kudzima?
    • RSA encryption
    • Normalized Least Mean Squares (NLMS)
    • JPEG compression
    • Dijkstra's algorithm
  7. Why must an adaptive echo-path filter keep updating during a call?
    • The far-end reference changes its language every second
    • The microphone stops recording whenever a door opens
    • Room acoustics can change when people or objects move, changing the path from speaker to microphone
    • A fixed filter automatically learns new room conditions without updates
  8. What kinds of recordings are included in Microsoft's AEC Challenge datasets?
    • Only music recorded in anechoic chambers
    • Only far-end speech with no microphone signal
    • Only speech with no echo or near-end speaker
    • Single-talk and double-talk recordings from real devices and speakers, plus synthetic data
