How do I call rasa from this code snippet?

from gtts import gTTS import speech\_recognition as sr import os

# import re

import webbrowser import smtplib

# import requests

# from weather import Weather

def talkToMe(audio): # “speaks audio passed as argument”

```
print(audio)
for line in audio.splitlines():
    os.system("say " + audio)

# use the system's inbuilt say command instead of mpg123
# text_to_speech = gTTS(text=audio, lang='en')
# text_to_speech.save('audio.mp3')
# os.system('mpg123 audio.mp3')

```

def myCommand(): # “listens for commands”

```
r = sr.Recognizer()

with sr.Microphone() as source:
    print('Ready...')
    r.pause_threshold = 1
    r.adjust_for_ambient_noise(source, duration=1)
    audio = r.listen(source)

try:
    command = r.recognize_google(audio).lower()
    print('You said: ' + command + '\n') How can I call rasa here?

#loop back to continue to listen for commands if unrecognizable speech is received
except sr.UnknownValueError:
    print('Your last command couldn\'t be heard')
    command = myCommand();

return command

```

```

talkToMe(‘I am ready for your command’)

Hey @MikeyBeez. I think I would try building a small custom connector which would define your bot’s input and output channels and connect your Rasa assistant to it. So basically, you would build your assistant with Rasa, define a custom connector like the following: [Custom Connectors](https://rasa.com/docs/rasa/user-guide/connectors/custom-connectors/). Then when you start the assistant’s server, it should listen for your input’s through the input channel you defined. There are a few tutorials where I build custom connectors. For example: [Going beyond ‘Hey Google’: building a Rasa-powered Google Assistant](https://blog.rasa.com/going-beyond-hey-google-building-a-rasa-powered-google-assistant/). Have a look and let me know if there is anything more specifically I can help.
