For example, if the input is a mora length of the phrase M phrase i,j,k = 7, the model should first generate a sequence of the mora word lengths [m 0 , m 1 , m 2 , m 3 ] = [3, 1, 2, 1], followed by a word sequence [w 0 , w 1 , w 2 , w 3 ] = [" (a-na-ta)", " (no)", " (ka-ta)", " (ni)" (your shoulder)].
we specified that a sequence of words with the mora length m is generated with some probability P (m|M phrase i,j,k ).
