We want the machine learning algorithms to able to handle a variety of background noise, and even relatively loud noises can be accepted provided that they don’t prevent you from hearing the entirety of the text. Quiet background music is OK; music loud enough to prevent you from hearing each and every word is not.
我们希望机器学习算法能够处理多样的背景噪音。一定程度的噪音是可接受的，只要它不妨碍您辨识整段文字。可接受安静的背景音乐，过于嘈杂以至于影响您辨识任何词语的音乐则不可以。
