Answer 1

You are probably experiencing it with USB microphone (e. g. on RaspberryPi). It tells you, that LiveSpeech doesn't know, which audio device to use for input. Luckily according to https://github.com/bambocher/pocketsphinx-python#default-config there are several configuration options - so you need to specify audio_device.

basically lets do:

for phrase in LiveSpeech(audio_device=3): print(phrase)

where 3 please replace with your desired microphone ID. Now how to get it:

import pyaudio

p = pyaudio.PyAudio()
for i in range(p.get_device_count()):
    print(p.get_device_info_by_index(i))
#otherwise you can do:
print(p.get_default_input_device_info())

There are several topics on how to properly set up USB microphone on RaspberryPi - if its your case, let me know.
