雅思口语6分和7分的区别参考以下表述：

6分：speaks at length without noticeable effort or loss of coherence。

首先要能够表达一定长度的回复，且没有明显的语用失误和连贯问题。

7分：speaks fluently with only occasional repetition or self-correction; hesitation is usually content-related and only rarely to search for language。

7分要求考生在表达时流利且少有重复和自我修改，即使是停顿也是为了思考内容相关而非语言相关。
