5.4.5 Word Internal CD Models: Mixture Splitting![]() The procedure for mixture splitting context dependent models is much similar as the procedure for word or monophone models. To review mixture splitting and its purpose, return to Section 5.2.5. The following procedure demonstrates how to split two, four, and eight mixture models. 2 Mixtures From the directory:
