Phonetic modeling includes the steps of forming triphone grammars (

11

) from phonetic data, training triphone models (

13

), clustering triphones (

14

) that are acoustically close together and mapping unclustered triphone grammars into a clustered model (

16

). The clustering process includes using a decision tree based on the acoustic likelihood and allows sub-model clusters in user-definable units.
