Detailed Description

Combine the statistics from multiple segpass or vitpass runs into an updated model.

Read the statistics written out by multiple segpass or vitpass runs and dervie an updated model.

Parameters

-ct<em>FileName(s)</em><a	name="spr_ct2hmm.ct" class="el"> Stat files created by segpass or vitpass that must be accumulated.
-ctx<em>FileName(s)</em><a	name="spr_ct2hmm.ctx" class="el"> Stat files created by segpass or vitpass that must be subtracted, e.g. for a leaving-one-out scheme.
-cto<em>FileName</em><a	name="spr_ct2hmm.cto" class="el"> Output stat file created by summing all input stat files.
-arcd<em>FileName</em><a	name="spr_ct2hmm.arcd" class="el"> Unit file name (.arcd or .cd format).
-h<em>FileName</em><a	name="spr_ct2hmm.h" class="el"> The input HMM file.
-g<em>FileName</em><a	name="spr_ct2hmm.g" class="el"> The input MVG file (gaussians).
-sel<em>FileName</em><a	name="spr_ct2hmm.sel" class="el"> The input select file name (tied gaussian).
-am_opt<em>Options</em><a	name="spr_ct2hmm.am_opt" class="el"> Extra options for loading the acoustic model. A non-default acoustic model can be selected by having '=<am_type>;' as first option. See cwr_am_tbl.c for a list of acoustic models available.
-ho<em>FileName</em><a	name="spr_ct2hmm.ho" class="el"> The output HMM file. Equals the input HMM if not specified (and no count file is requested).
-go<em>FileName</em><a	name="spr_ct2hmm.go" class="el"> The output MVG file. Equals the input MVG if not specified (and no count file is requested).
-selo<em>FileName</em><a	name="spr_ct2hmm.selo" class="el"> The output select file name (tied gaussian).
-MinCount<em>Value</em><a	name="spr_ct2hmm.MinCount" class="el"> Minimal count required for the state statistics to be updated.
-LMsil<em>Value</em><a	name="spr_ct2hmm.LMsil" class="el"> Minimal (logarithmic) probability for silence.
-LMspch<em>Value</em><a	name="spr_ct2hmm.LMspch" class="el"> Minimal (logarithmic) probability for speech.
-REPflag	relative minimal probabilities For each label probability / gaussian weight, a different minimal value is calculated from the value given with the option -LMspch, proportional to its relative occurrence in the data. For explanation, see ct_to_oprob2().
-LMtrans<em>Value</em><a	name="spr_ct2hmm.LMtrans" class="el"> Minimal (logarithmic) probability for transition.
-sf<em>Factor</em><a	name="spr_ct2hmm.sf" class="el"> Smoothing factor: smooth the output HMM with the input HMM (mode=TRAIN), or with uniform probabilities (mode=INIT).
-pool<em>PoolingString</em><a	name="spr_ct2hmm.pool" class="el"> P: Pooled: ovlen dimensional sigma vector is the same for all gaussians. FP: Fully Pooled: only one sigma remains, it is the same for all gaussians AND dimensions.
-vm<em>Value</em><a	name="spr_ct2hmm.vm" class="el"> Lower limit on the sqrt(variance) relative w.r.t. the weighted average of the variances.

Adjust an HMM based on statistics from segpass or vitpass runs.
