Which statement is a disadvantage of voice driven interfaces?

• A. Strong accents may not be understood
• B. Popular in sat-navs
• C. Speech input is faster than keyboard input
• D. Reduces typing mistakes

Answer: (A)

The main idea here is that voice-driven interfaces can struggle with understanding certain ways of speaking, which is a drawback. Strong accents can cause the speech recognizer to misinterpret words because the system is often trained on more standard pronunciation. When the accent isn’t well represented in the training data, accuracy drops, you may need to repeat phrases, or the system might misinterpret commands. This disrupts the interaction and can make the interface frustrating or unreliable in some cases. If you think about the other statements, being popular in sat-navs shows a real-world use and usefulness, which is a positive aspect. Speech input being faster than typing and reducing typing mistakes are typically benefits of voice input, not downsides.
