Is it possible to use Python SpeechRecognition on Django?

Question

I have the following script which works when running in a terminal:

All is does is turn microphone speech to text.

import speech_recognition as sr

# obtain audio from microphone
r = sr.Recognizer()
with sr.Microphone() as source:
    print("Say something!")
    audio = r.listen(source)

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("Google Speech Recognition thinks you said " + r.recognize_google(audio))
except sr.UnknownValueError:
    print("Google Speech Recognition could not understand audio")
except sr.RequestError as e:
    print("Could not request results from Google Speech Recognition service; {0}".format(e))

Would it be possible to have this work on Django after pushing a button? Something like:

View:

import speech_recognition as sr

# Create your views here.
def index(request):
    return render(request, 'app/index.html')

def text(request):
    r = sr.Recognizer()
    with sr.Microphone() as source:
        #print("Say something!")
        audio = r.listen(source)

    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)`
        speech = r.recognize_google(audio)
    except sr.UnknownValueError:
        speech = "Google Speech Recognition could not understand audio"
    except sr.RequestError as e:
        speech = "Could not request results from Google Speech Recognition service; {0}".format(e)
    return render(request, 'app/text', {'speech': speech})

Template:

<form action="/text/" method="post">
    <input type="button" value="Start listening" />
</form>

Is this possible? Am I close or not at all?

Answer 1

Django has no access to the users' computers so if you try to record from a microphone you will be using the server's microphone, if it has one.

You need to record using JS/HTML5 and then send the data to django to process with AJAX. You might even be able to stream it but it's probably not worth the effort.
