Why can a handcrafted feature representation limit the performance of a sound classification system?

True or False: Phoneme labels are a linguist-designed approximation of speech sounds rather than a perfect recording of the sound waveform.

Mel-frequency cepstral coefficients summarize sound, but they also _____ some of the original detail.

Match each speech-system component to the limitation it creates.

Order the reasoning chain showing how a fixed intermediate representation can cap system quality.

What happens if a model must use a very coarse representation that leaves out important detail?

True or False: Hand-crafted audio features always preserve every detail of the original waveform.

Relying only on a hand-designed phoneme layer will _____ the speech system's accuracy.
