TL; DR: Win 10 IoT for RasPi does it. ----------------- Windows 10 IoT for Raspberry Pi comes with offline speech recognition API. It was not hard to slap some code together that turns on a light when someone says "banana" at a hackathon. Sounds like exactly what you need. >If it helps I'm happy to reduce vocabulary to a dictionary of words You will do it with an XML grammar file for offline recognition[4].

The Microsoft offline speech recognizer is pretty good. I did some work with it many years ago [0]. The only problem we had was with accents: My French co-worker had to use his most obnoxiously over-the-top American accent for reasonable accuracy. ISTR that we could switch to Australian English for the Aussies and Kiwis. [0] https://github.com/spc-ofp/ObserverLengthSampler https://github.com/spc-ofp/ObserverLengthSampler

This is really interesting, but I have a few questions: - The setup guide shows a Windows system making a Windows iot version. Can't I just download an iso and flash it to an sdcard with dd? Does it need a license? - The demo projects show C# and while I can develop in monodevelop, I don't have a Windows to compile it with. Is a C# compiler included in Windows iot's .NET distribution or are there also cross-platform (interpreted) languages that run on Windows iot (e.g. Python3)?

  You might be able to use .NET Core which is opensource and can run on Linux/Mac.

  So, recently I played with Windows10 IoT. Win10 IoT is written to the SD card, and left to first-boot inside the Pi (this bit takes AGES). While it's doing that you install the Win IoT dashboard toolkit onto your PC (Windows only). The Dashboard will find your Win10 IoT Pi on the network, there's a few demo apps pre installed you can play with. It's a free OS, but you need to pay for a dev licence if you want it to not reboot every 24 hours. (There's also an on screen non-production warning). Now you fire up Visual Studio, which has gained the ability to build C# apps on ARM. You write a small app, including using the visual form designer, and you debug using the PC based Win IoT emulator, or you deploy it directly (using VS) to the the Pi. Once you are happy with your app, you have to bake it into a new OS image that gets written to the SD card(s) for proper deployment. Win10 IoT can only run one app in the foreground. It does not have a classic desktop, which should be fine for embedded or kiosk type applications. Personally, I found it clunky and slow, even on a fast Pi. There's also a fair amount of restrictions applied to your app (think the same restrictions as an Android or iOS app) so if you are used to your C# app having full (read) access to the machine it's running on, you won't get that on Win IoT. If you want to develop GUI rich apps on the Pi, there are far better alternatives (Mono, Python/GTK etc. on Raspbian). This is just my take on Win10 IoT. I'm a Windows guy by profession so I don't have an anti-MS bias here.

Sounds good to me. RasPi are solid performers to us. I'm assuming the XML would need to be updated as the dictionary changes. Sounds easy enough. The loading of languages might get fussy/impossible if I want multiple. A stretch goal is to support multiple languages from the same device. I'd be hoping I can also load in text-to-speech as well either separately or as part of same application. From what I've read the windows approach to the Pi is more like an appliance. Your application takes over the whole device. This is fine as long as I can load in more functionality to that application. I need to read more about this. Thanks for the pointers.

Does the IoT version track everything you do and cram ads down your throat like the regular version of Win 10?

  I don't think this question is in good faith, but the answer is no.

    I worded it as an adversarial way but it was a serious question. I'm glad to hear they don't.
