Yes, it will work. After that two native speakers should review and accept it (one can be yourself).
I would heavily advice against having single words. This makes the whole recording process super boring for contributors.
@kodyglock let’s add some fun and interesting sentences, so contributors recording don’t need to feel like machines 
many conversations include single-word questions or answers. It would be a shame to not include them.
Yes, but for speech recognition these words do not need to be single in a recording. It’s way more fun if those words are part of a bigger sentence.
We also recently removed single words from Cantonese as these were super boring.
