AssertionError: This audio source is already inside a context manager

[vic047]

Steps to reproduce

I am writing an Voice Assistant. It hears wake word and then should do stuff. I installed all the dependencies for speech_recognizion.

I have a recognizer class for wrapping the speech recognition libary

import speech_recognition as sr

class Recognizer(object):
    def __init__(self) -> None:
        self.__recognizer = sr.Recognizer()
        self.__mic = sr.Microphone()
        with self.__mic as source:
            self.__recognizer.adjust_for_ambient_noise(source, duration=0.2)
        self.__stop_listen = None
        self.__callback = None

    def listen(self):
        with self.__mic as source:
            try:
                audio = self.__recognizer.listen(source)
                return self.transcribe(audio)
            except sr.UnknownValueError or sr.RequestError as e:
                self.handle_recognizer_err(e)
                self.listen()

    def recognizer(self, text):
        ...

I also have a Speaker class for wrapping the tts libary ()

import pyttsx3 as tts

class Speaker:
    def __init__(self) -> None:
        self.__speaker = self.default_speaker()
        self.__stop_listen = None

    @staticmethod
    def default_speaker():
        speaker = tts.init()
        speaker.setProperty('rate', 150)
        voices = speaker.getProperty('voices')
        speaker.setProperty('voice', voices[0].id)
        return speaker

    def stopword_callback(self, words):
        print("Something was said!!", words)
        if r.is_stopword(words):
            self.__speaker.stop()
            self.__stop_listen()

    def say(self, msg):
        self.__speaker.say(msg)
        self.__speaker.runAndWait()
        self.__speaker.stop()

    # This is where the error occurs
    def say_stoppable(self, msg):
        self.__stop_listen = r.listen_in_bg(self.stopword_callback)
        self.__speaker.say(msg)
        self.__speaker.runAndWait()
        self.__speaker.stop()
        if callable(self.__stop_listen):
            self.__stop_listen()

Expected behaviour

I want to be able to abort the Assistant while he is speeking with a (or more) stop word(s). Therefore I try using the 'listen_in_background' function.

Actual behaviour

The thread from 'listen_in_background' throws an error

Exception in thread Thread-1:
