Yeah, good point. I think the FAQs need a question on "How to chat with Polly," or something similar which will give examples of the type of prompts you can use, and that you can use your native language to help if you're struggling, like you suggest. Thanks for the feedback.
Maybe even just show a sample conversation that includes some of those methods. I think especially for rank beginners in a language the biggest problem will be overcoming the problem of starting to say something you don't know how to finish, and so just getting people aware they can fall back to English (or other languages, I spoke Norwegian to it in the middle of a French conversation) might make people more comfortable getting started.
