Chatbot rasa voice

I have developed a text chatbot with rasa and opc ua but I would like to integrate voice and at the end it would be a chatbot that also allows audio. I haven’t found much information on what are the best possibilities. Do you recommend me one in particular? I’ve heard about Botium Speech, NVIDIA Riva, Mozilla, Alexa and Google but I don’t know what languages they allow, their pros and cons and I haven’t found much information about how to integrate them into a chatbot. If you have any information or know where I can find it, I would be very grateful for your help.

Have you considered rasa’s twilio voice connector?
