Detailed Description

Node in a word lattice.

A node corresponds to a number of hypothesized instances of a word which all share the same starting point.

Member Function Documentation

POCKETSPHINX_EXPORT const char * ps_latnode_word	(	ps_lattice_t *	dag,
		ps_latnode_t *	node
	)

Get word string for this node.

Parameters

dag	Lattice to which node belongs.
node	Node inquired about.

POCKETSPHINX_EXPORT const char * ps_latnode_baseword	(	ps_lattice_t *	dag,
		ps_latnode_t *	node
	)

Get base word string for this node.

Parameters

dag	Lattice to which node belongs.
node	Node inquired about.

POCKETSPHINX_EXPORT ps_latlink_iter_t * ps_latnode_exits ( ps_latnode_t * node )

Iterate over exits from this node.

Parameters

node	Node inquired about.

POCKETSPHINX_EXPORT ps_latlink_iter_t * ps_latnode_entries ( ps_latnode_t * node )

Iterate over entries to this node.

Parameters

node	Node inquired about.

POCKETSPHINX_EXPORT int32 ps_latnode_prob	(	ps_lattice_t *	dag,
		ps_latnode_t *	node,
		ps_latlink_t **	out_link
	)

Get best posterior probability and associated acoustic score from a lattice node.

Parameters

dag	Lattice to which node belongs.
node	Node inquired about.
out_link	Output: exit link with highest posterior probability

Returns: Posterior probability of the best link exiting this node. Log is expressed in the log-base used in the decoder. To convert to linear floating-point, use logmath_exp(ps_lattice_get_logmath(), pprob).
