I would assume they are only going to be doing the raw data collection and maybe cleanup and annotation, and that data should be made available so you can train what you like.

If you poke around github and the Kaldi lists a bit more you can see that they are experimenting with and probably planning to use Kaldi.

I wonder what they plan to do for provisioning. It is one thing to collect data and train models, but quite another to make the service available over the web in an unlimited capacity. And we are not yet to the point where you can reasonably expect to run a high quality open-vocabulary STT system in your browser. The search network is typically in the GBs range.

It's weird to me that they publish the project about having an open dataset of voice data, with only a promise the open it up later.

It's Mozilla, they likely just don't have the infrastructure/code in place yet. They definitely get my trust for believing they actually will. They have been very good in the past about keeping things open. They make mistakes sometimes, but their goals are all about being open.

thanks for the vote of confidence! yes we will absolutely open this data up, and it's just a matter of collecting enough data to be useful, and then building the UI. we have a goal of achieving this by the end of 2017, so stay tuned!
