BLEU的音标是/"bluː/。BLEU通常被翻译为“布卢”。基本翻译取决于语境和上下文。BLEU也可以被视为一种测量自然语言处理任务中模型输出与参考答案相似度的指标。速记技巧是使用缩写形式来表示BLEU，例如可以使用“蓝”来代替BLEU。

BLEU (Bilingual Evaluation Understudy) 的英文词源可以追溯到其设计者 NIST，他们为了评估机器翻译的质量而提出这个指标。BLEU 是一个基于 n-gram 的统计模型，用于测量翻译结果的相似度。

BLEU 的变化形式主要有加后缀或前缀构成不同的含义，如“differential BLEU”或“weighted BLEU”，分别表示差异的 BLEU 或加权的 BLEU。
