I finally saw VoiceStudio advertised on my Xbox One. If you take the time to go through with it, it basically collects user data so they can improve voice commands by region for Xbox One. Worthwhile and only takes a few minutes to do. You'll find it under the Apps category of the Store.
Also, if you are an achievement hunter, there are achievements for submitting up to seven collections of voice samples.
