Hi everyone, I’ve been increasingly impressed with results for training models (mostly computer vision tasks) on synthetic data. I noticed Google commented on using data from speech synthesis models to train the [latest version of their on-device ASR model](https://arxiv.org/abs/1811.06621).

​

[I wrote a brief primer](https://heartbeat.fritz.ai/synthetic-data-a-bridge-over-the-data-moat-29f392a52f27) on some of the things I’m seeing as well as limitations / open questions and was wondering if anyone here has used synthetically generated data in production?
