Detailed Description

SOME ASSUMPTIONS

• All phones (ciphones and triphones) have same HMM topology with n_state states.
• Initial state = state 0; final state = state n_state-1.
• Final state is a non-emitting state with no arcs out of it.
• Some form of Bakis topology (ie, no cycles, except for self-transitions). Phone-level sentence HMM structures: pnode_t: nodes of phones forming sentence HMM. plink_t: a link between two pnode_t nodes. A phone node may have multiple successors and/or predecessors because of multiple alternative pronunciations for a word, as well as the presence of OPTIONAL filler words.

Assumptions:

• No cycles in phone level sentence HMM.
