Infinite loop:
1. Reading microphone for 3 sec and generation .wav file.
2. Creating thread with voice_command_processor() method for converting speech to text.
3. IF wake word is detected (in my case Gideon):
a. Clearing recognized_text global variable.
b. Turing on the LED.
c. Audio reply with "how can i help you"
d. Start reading from pyaudio stream for next 5 sec for question.
e. Convert the audio to text using voice_command_processor().
