Are you using a wired or wireless mic?
Strictly based on the symptom you describe, it would indicate that the microphone is overdriven. More often I have seen this occur with wireless mics. Some people have a tendency to increase the receiver volume to MAX which will show as clipping on the mixer.
Bottom line is that overdriven mics will degrade the singer's vocals by making them sound scratchy; as you described in your post.
This is just my take on the topic based on limited input; your mileage may vary.
