Hello,

I need to know, what specifications should I look for when I use a microphone for speech recognition using Pocketsphinx?

I have already tried two microphones for recording:
1- Sinheiser free speaker, whose microphone has the following freq. range : 150 to 6800Hz
2- A gaming headset with frequency range : 20 - 20000 Hz.

The Sinheiser microphone showed really bad results, meanwhile the headset gave better results.

So, does the used microphone play a role in defining the accuracy? and what can be your recommendations for a suitable microphone ?

P.S. I use the 16Hz acoustic model.

Thanks in advance!
