Allophone Tool

The Allophone-Tool provides information about the allophones used by the acoustic model, including allophone-state to mixture index mappings and the allophone properties supported by CART.

Parameters:

lexicon : see Lexicon Configuration

acoustic model : HMM setup, see Acoustic Model Configuration

decision tree : optional, see cart_estimation and CART Trainer

Channels and Files:

allophones.store-to-file : store the complete allophone state list

dump-allophone-properties : channel, store allophone properties, see [[CART question file]]

dump-allophones : channel, all allphones

dump-allophone-states : channel, all allophone states

dump-state-tying : channel, allophone state tying
