SNIPS and ASR Injection for Deutsch

Hello,
i am trying to get the SNIPS addon running in hass.io. My system has to understand german and as far as i know about SNIPS.AI it understands only english words. All other languages has to be trained. So is there a solution to feed the asr-injection with all my words, like “Wintergartenbeleuchtung” to the slot light and “rot” to the slot color and “Steckdose” to the slot switch? SNIPS doc for injection

Or am i wrong and it should work in german without this step?

Greetings from germany.
