You need to be able to hear every word of the recording. We want machine learning algorithms to be able to handle a variety of background noise, and even relatively loud noises or quiet background music can be accepted provided that they don’t prevent you from hearing the entirety of the text. Crackles or ‘breaking up’ that prevent you hearing the text means you should reject the clip.
录音中的每一个字都应清晰可辨。我们希望机器学习算法能够处理各种背景噪音，甚至可以接受相对嘈杂的噪音及安静的背景音乐，但前提是这些声音不妨碍您听清整个文本。如出现妨碍您听清文本的杂音，或朗读声音断断续续，则将其驳回。
