Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

1. Waa maxay macnaha 'mel' ee ku jira MCCC?
   • Magaca hal-abuuraha
   • Nooc ka mid ah lakabka shabakada neerfaha
   • Unug dhawaaq dheer oo decibels ah
   • Miisaanka soo noqnoqda garaadka ee u ekaysiiya maqalka garaadka aadanaha
2. Isbadalkee ayaa la dabaqay ugu dambeyntii si loo soo saaro iskuxirayaasha bowdada?
   • Beddelka cosine Discrete
   • Fourier transformer
   • Beddelka wavelet
   • Hilbert isbeddel
3. Waa maxay sababta MVCC-yadu ay ugu adag yihiin goobta hadalka?
   • Waxay xoojiyaan inta jeer ee aasaasiga ah
   • DCT-du waxay kala saartaa qaabka dhawaaq-mareenka gaabis ah iyo is-waafajinta degdegga ah
   • Waxay iska indhatiraan baaxadda gebi ahaanba
   • Waxay marka hore u beddelaan codka qoraalka
4. Qiyaastii imisa xabbo oo MMFC ayaa sida caadiga ah loo hayaa qaabkiiba?
   • 100 sax ah
   • Ku dhawaad 1,000
   • Ilaa 13
   • Kaliya 1
5. Waa maxay sababta loggu loogu dabaqay tamarta mel-band?
   • Si loogu badalo qoraal
   • Si aad meesha uga saarto dhammaan qaylada
   • Si loo kordhiyo heerka saamiga
   • Si loo qiyaaso sida dadku u arkaan qaylada
6. Nidaamyada maqalka ee barashada qoto dheer ee casriga ah, maxaa inta badan bedelaya MFC-yada gacanta lagu sameeyay?
   • Waveforms ceeriin ama spectrograms log-mel oo lagu quudiyay cidhifyada hore ee la bartay
   • Qoraalada cad ee qoraalka ah
   • Kaliya is beddelka Fourier-ka oo aan lahayn miisaan
   • faylasha MIDI
7. What do the MFCCs summarize after the discrete cosine transform?
   • The original waveform sample by sample
   • A compact representation of the log mel-spectrum’s broad shape
   • The exact phase of every frequency component
   • The semantic meaning of a spoken sentence
8. What information is lost when a signal is summarized by a small set of MFCCs?
   • The recording’s entire duration
   • Every estimate of average loudness
   • Fine spectral detail and phase information
   • The existence of a time axis
