PyAudio delay

[hast]

So i'm currently making a voice assistant thingy as a school project and i have quite a problem with pyaudio.

while True:

        chunk = 256
        
        # get audio from the microphone                                                                       
        r = sr.Recognizer()                                                                                   
        with sr.Microphone() as source:                                                                       
            print("Ready")                                                                                   
            audio = r.listen(source)   
 
        try:
            print("You said " + r.recognize_google(audio))
            if r.recognize_google(audio) == "hello":
                f = wave.open("hal1.wav","rb")
                p = pyaudio.PyAudio()
                stream = p.open(format = p.get_format_from_width(f.getsampwidth()), channels = f.getnchannels(), rate = f.getframerate(), output = True)
                data = f.readframes(chunk)
                while data:
                    stream.write(data)
                    data = f.readframes(chunk)
                stream.stop_stream()
                stream.close()
                p.terminate()
        except sr.UnknownValueError:
            print("Could not understand audio")
        except sr.RequestError as e:
            print("Could not request results; {0}".format(e))

The problem is in the title, there is a MASSIVE delay before the wav file is actually played. (sometimes it can take up to 20 seconds to get it played back)
And for a voice assistant that is unacceptable.
I don't know where the problem is exactly, but i'm pretty sure it's not the speech recognition part.
Does anybody have a clue why this is happening?
