How to get a voice file in rasa

Need to get a voice file while exposing rasa as service. How to do that ?

Hello.

There are a lot of questions about this on the forum. What have you tried?

Hi Chris, We need to get an audio file as an input from mobile app, We need to know how to get in a rest API (custom connector) , is it possible to get in it ? Next we tried to get from socket i/o – Build an AI voice assistant with Rasa Open Source and Mozilla tools | Rasa | The Rasa Blog | Rasa but we are not sure how socket i/o works In which way is it possible to get audio file?
