My internal mic can detect keyboard sounds and clicking, but cannot detect voices. What is wrong?

The sound of keyboard clicking when I type and sound of clicking my touchpad can be detected by the internal mic, however the mic cannot detect my voice by any means. What is wrong? Is it a hardware failure?
MacBook Air, OS X Yosemite (10.10.3)
