title: Which API key do I use in SpeechRecognition (Google) in python
body: <p>I am working on a project that uses voice recognition in python and I was looking at some example code, I was wondering which API key to use and what does it look like.</p>
  
  <pre><code>def callback(recognizer, audio):
  # received audio data, now we'll recognize it using Google Speech Recognition
  try:
      # for testing purposes, we're just using the default API key
      # to use another API key, use `r.recognize_google(audio, key="GOOGLE_SPEECH_RECOGNITION_API_KEY")`
      # instead of `r.recognize_google(audio)`
      print(recognizer.recognize_google(audio)) &lt;-- right there
  except sr.UnknownValueError:
      pass
  except sr.RequestError as e:
      pass
  </code></pre>
