Conversion from speech to text has low performance

Hi, I am using this tool for speech to text conversion, but the output is not similar with the original input.Any reasons for low perfomance?
a) Bad microphone quality?
b) Wrong usage of tool or tuning some parameters?
c) Bad accent, since english is not
my native language?
