How to make conversational voice interviewer (using custom model)?

Hi, I want to make a conversational style interviewer using the Assistants as I’ve done some customisations to the model. As of now, I’ve implemented a start and stop button to send the reply and get the reponse back from the assistant, as the data is travelling in chunks, as mentioned in the documentation. I want to implement the same in a conversation style. Please guide me on how can I achieve this.
