Flf-Tool

The FLF lattice tool runs a lattice processing network for a Bliss corpus or a sequence of batches depending on the choosen nodes. The network has to be provided as RWTH ASR Configuration file, i.e. the use of the option --config is mandatory for running a network.

Usage

default options:

--help : help

--config : configuration file

The following command line commands are supported:

(none) : runs the network

init : initializes the network, but does not run it

parse : parses the network, but neither initializes nor runs it

help : gives some general help on how setting up a network

help list : lists all nodes; help is available for each node

help NODE : gives help to the specific node

Structure of a network

[*.network]
initial-nodes    = INITIAL_NODE ...

[*.network.INITIAL_NODE]
type             = TYPE
links            = PORT->TARGET_NODE:PORT ...
...

[*.network.TARGET_NODE]
type             = TYPE
...

Common initial nodes are speech-segment and batch, common final node is sink. The links syntax can be shorten. The header PORT-> can be skipped; source-port is set to 0. In addition or alternatively the tail :PORT can be skipped; target-port is set to 0.
