Support needed - Python pocketsphinx works not like pocketsphinx_continuous.exe #58

Description
I have solution (jsgf, dict, hmm), that works well with
pocketsphinx_continuous -hmm zero_ru.cd_cont_4000 -dict vocabular.dict -jsgf calc.jsgf -inmic yes
Now I am trying to port it to Python pocketsphinx 0.1.15 (https://pypi.org/project/pocketsphinx/) and I see, in verbose output, that config of Python pocketsphinx is not same to pocketsphinx_continuous config.
As result Python pocketsphinx makes a lot of wrong phantom detections.
My Python script is very simple:
speech = LiveSpeech(
verbose=True,
hmm='c:/Projects/pocketsphinx-5prealpha-win32/pocketsphinx/bin/Release/x64/zero_ru.cd_cont_4000',
lm=False,
jsgf='c:/Projects/pocketsphinx-5prealpha-win32/pocketsphinx/bin/Release/x64/calc.jsgf',
dic='c:/Projects/pocketsphinx-5prealpha-win32/pocketsphinx/bin/Release/x64/vocabular.dict',
allphone_ci=False,
vad_threshold=2.0,
kws_threshold=1.0,
)
for phrase in speech:
print(phrase)
By comparing text files with outputs I see, that pocketsphinx_continuous has in output

but Python pocketsphinx has

Now I am trying to make Python pocketsphinx to work (or, to config) same as pocketsphinx_continuous.
How to make Python pocketsphinx use CMN='current' instead of CMN='batch'?
Ie, how to make Python pocketsphinx show in output

instead of
