Rasa 3.x - Voice Assistant

Hi community! Has anyone here given a try to implement voice chat functionality in rasa version 3 and above?

I understand there have been certain blogs and sample examples on this, but all of them seem to have been deprecated. Such as this one: Build an AI voice assistant with Rasa Open Source and Mozilla tools | Rasa | The Rasa Blog

If there is anyone who has knowledge on this or any resources which can help me take a path, would be deeply appreciated. Thanks so much!
