研究人员将信息论之父香农（Claude Shannon）创造的信息熵值应用于测量动物语言的信息量。以英语为例，它有26个字母和一个空格，根据香农的计算，跟随单个字母的单字母平均信息熵是4.03比特，跟随双字母序列的平均信息熵为 3.56比特，跟随三字母序列的平均信息熵是3.3比特。Reginald Smith利用香农的方法，通过测量动物语言的复杂度反过来推测语言所包含"字母"的大小和数量。根据他的计算结果，宽吻海豚的语言由27个单字母音节，5个双字母音节，4个或5个三字母音节构成；座头鲸的语言则由6个单字母音节，17或18个双字母音节构成。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
