Speak is an interactive site for several languages but it has quite a big section for French. It is not as good as Yabla but nevertheless it has sections which are very helpful for teaching basic conversation. It is something students would be able to follow themselves. I wouldn’t be using it all the time. I’d be selecting the parts of the site I think are very good and taking control of that myself with the students and then I’d be happy for them to use it themselves when they wanted to. There is plenty of spoken French and some of it is much better than other parts of it which is why I am recommending you test out anything before you use it. The excellent parts really are excellent and the map at the beginning to get you orientated is a great idea.
