Is this audio even correct? Doesn't it sound weird or anything? Can you distinguish between those inital h's (in almost all the recordings I've heard) and g in gaat here? I can clearly hear the difference in the recordings on Forvo but the TTS here doesn't seem to be doing a very good job with pronouncing those inital h's.
I think I know what you mean. Dutch spelling is actually even more regular than German spelling, so not at all like French spelling. But Dutch phonetics has some strange features. One of them is that g is generally pronounced similar to a very strong h - easy to miss, and not at all like a German g. Also double a is much shorter than you might expect coming from German.
Nevertheless, I am sure that in the long run Dutch is much easier to learn than German. (Though I haven't really had a symmetric experience myself, being a native speaker of German.)
