Error: didn't return an HttpResponse object. It returned None instead

I want to press a button in an html-template 

              <form action="{% url 'speech2text' %}" class="card-text" method="POST">
                  {% csrf_token %}
                  <button class="btn btn-primary btn-sm" type="submit">Start</button>
              </form>

              <p> Sie haben das folgende gesagt: </p>
              <p> {{ speech_text }} </p>

by pressing the button, the code in the following view shall be executed and send back the result into the template:

def speech2textView(request):
    if request.method == "POST":
        r = sr.Recognizer()
        with sr.Microphone() as source:
            audio = r.listen(source)
            text = r.recognize_google(audio, language="de-DE")
            args = {'speech_text': text}
            return render(request, 'speech2text.html', args)

Whats wrong here? many thanks for your help.

I edited the code again and now it is working. I would like to share this. Many thanks to this community.

def speech2textView(request):
    args = {}
    if request.method == "POST":
        print(request.method)
        r = sr.Recognizer()
        with sr.Microphone() as source:
            audio = r.listen(source)
            text = r.recognize_google(audio, language="de-DE")
            args = {'speech_text': text}
    return render(request, 'speech2text.html', args)

try to checking the context with adding a print command and inspecting in your command window like this 

def speech2textView(request):
    if request.method == "POST":
        r = sr.Recognizer()
        with sr.Microphone() as source:
            audio = r.listen(source)
            text = r.recognize_google(audio, language="de-DE")
            args = {'speech_text': text}
            print(args)
            return render(request, 'speech2text.html', args)

if you didn't see the data in your command window I think the problem is in your recognition step or on the request step keep tracking with printing some data to see where is the code stuck or fail.

This error occurs because there was no return! It seems that return render(request, 'speech2text.html', args) doesn't work. Try adding return render() outside of the with, and if the same error occurs try adding that outside of the request.method == "POST":. This way u can check where the problem occurs.
