Google Cloud Speech streaming in the Unity Game Engine

_x000D_ No, streaming in Google Cloud Speech API requires gRPC, and gRPC isn't supported in Unity at the moment. Once gRPC is supported, I'd expect the client library to port very easily - or just work out of the box, potentially. Supporting gRPC in Unity is far from trivial, partly because it relies on a later version of .NET than Unity supports1, and partly because it relies on a native component which will need to be compiled for each of the architectures your app will target. (It's also unclear whether it will ever be feasible for web player, but that's not supported any more anyway.) I've done some prototyping of gRPC on Unity, and it's "on the radar" in that there are teams in Google who would definitely like it to be supported - but there's nothing to announce at the moment, I'm afraid. 1 I'm aware that Unity is moving on, but ideally we'd like to support old versions as well.
