Which statement is a disadvantage of voice driven interfaces?

• A. Background noise can interfere
• B. Popular in sat-navs
• C. Speech input is faster than keyboard input
• D. Reduces typing mistakes

Answer: (A)

Voice-driven interfaces rely on turning spoken words into commands, so anything that distorts the speech signal can cause problems. Background noise—like traffic, wind, or other people talking—can be picked up by the microphone and muddle what the user is saying. That makes it harder for the system to recognize the command correctly, leading to errors, longer interaction times, and frustration. So, interference from background noise is a real downside of voice control. The other statements describe positive or neutral aspects. Being popular in sat-navs is about adoption, not a drawback. Saying speech input is faster than typing describes a potential speed advantage, not a disadvantage. Reducing typing mistakes is also an advantage, not a drawback.
