Chatbot on Raspberry Pi using MS Bing Speech Service -- 2

I am planning to build a project of a chatbot demo on Raspberry pi, which can listen and response verbally to the user/speaker in English. Three simple steps of design following: 1. STT 2. A Conversation Service using MS bot framework 3. TSS All three steps using MS service and run on Raspberry pi through its hardware like microphone/speaker, and the conversation can be managed and updated using bot fromework (machine learning too). The speed of responding also mutl-threads should be considered and handled technically to in order to deliver a good user experience, in other words you don't wait too long more than 2 seconds for chatbot to respond anything. Notice I am not asking for a home appliance automation control project but rather a talking-back device for language training, although they're similar in a way. I would expect this project done using Python/Node.js/C#. I can provide the credentials of MS paid Speech service to help develop. Thank you for reading.
