W ords that are more frequently used tend to be shorter in human language [1, 2] [Figure 1(a)]. The length of a word can be measured in letters or phonemes. The shortening of words with frequency can be regarded as evidence of efficient coding: by employing shorter codes for more frequent words, it is possible to increase the rate of information transmitted [3]. This tendency is the rationale behind file compression techniques such as Huffman codes [4]. Efficient coding has not been reported in… Expand
