Context Dependent & Context Independent on an4

[Senjam Shantirani]

I followed the example in tutorial, and get the Context Dependent with 8 guassians.
The result is : SENTENCE ERROR: 72.3% (94/130) WORD ERROR RATE: 28.1% (216/773)

To do the Context Independent I set the following parameters in sphinx_train.cfg

(yes/no) Train multiple-gaussian context-independent models (useful
for alignment, use 'no' otherwise)
$CFG_CI_MGAU = 'yes';
(yes/no) Train context-dependent models
$CFG_CD_TRAIN = 'no';

I get the result same as SENTENCE ERROR: 72.3% (94/130) WORD ERROR RATE: 28.1% (216/773)

IS THE RESULT COMING SAME APPROPRIATE? OR ANYTHING WRONG IN MY SETTINGS in sphinx_train.cfg.

Please let me know how do I train and test with an4 the CI models.

Please advice.

You probably forgot to update acoustic model used for decoding in configuration file, you need to update it:

$DEC_CFG_MODEL_NAME = "$CFG_EXPTNAME.cd_${CFG_DIRLABEL}_${CFG_N_TIED_STATES}";``

I get the following in my model_parameter folder

/home/an4/an4/model_parameters/an4.cd_cont_200

/home/an4/an4/model_parameters/an4.ci_cont_flatinitial

Can you please suggest which is the final model for CI and CD here.
