説明

Logical HMM to map logical names to physical/pseudo HMM

This data maps logical HMM name to physical (defined) HMM or pseudo HMM. The logical HMM names are basically loaded from HMMList mapping file. Biphone/monophone HMM names, not listed in the HMMList file, are mapped to pseudo phones, which represents the context-dependent HMM set.

For example, if logical biphone HMM name "e-k" is defined in HMM definition file or its mapping is specified in the HMMList file, the Logical HMM name "e-k" will be mapped to the corresponding defined HMM. If "e-k" does not exist in both HMM definition file and HMMList file, triphones whose name matches "e-k+*" will be gathered to phone context-dependent HMM set "e-k", and the logical HMM name "e-k" will be mapped to this HMM set.

The context-dependent HMM is also called a "pseudo" phone in Julius.
