I think it is a good start based on what we know today.

I think it is a good idea to inform about the user that they will be asked to give permission.
Could we keep it as simple as possible? I am afraid that the error popup will be confusing.

Thank you so much for your input. There are many insightful comments that will help improve Wikispeech. We will make sure to take them into account. To do that we will create tasks in the Wikispeech backlog corresponding to those. However, we will probably not be able to prioritize most of them for the time being as we are focusing our resources elsewhere, more exactly we are implementing a better TTS engine. With that said, it is still possible that someone from the community would choose to work on them.
