I am totally new to this. I was working on speech_recogition api for python to make homeautomation via voice controle. But I wanted to improve accuracy and I dont know what exactly I did but am getting this error. Is there any good tutorial for this? Yes one thing, to install sphinxtrainer i just dir

./configure
make
sude make install

was that enough to beign with tutorial given here https://cmusphinx.github.io/wiki/tutorialadapt/
is that okay??.. I have many such questions. Please answer ASAP

You can install valgrind and run

 valgrind sphinx_fe -argfile en-us/feat.params -samprate 16000 -c arctic20.fileids -di . -do . -ei wav -eo mfc -mswav yes

to get more information about crash

Thanks, I found out that my recodings had a problem. I should have recorded it in 16000 samplerate. But the recorder's default was not that and I did't paid much heed to it.
