Yeah I think there are two sides to this coin (and just for clarity - all of this relates to Picroft, not Mimic 3 the TTS engine that just launched). The audio hardware makes a huge difference to audio input which is why we've developed the custom SJ201 board that's in the Mark II. But even on DIY units we have been making big improvements on the wake word detection by better balancing our training data sets. Once the Mark II is shipping there are additional wake word improvements on the roadmap. Eventually the system will optimize for the users of each device. So the wake word model on your device wouldn't be exactly the same as the model on mine. We've also ported the Wake Word model to Tensorflow Lite which means it uses a small fraction of the system resources that it used to :D We're also about to make some bigger changes to mycroft-core that will help to support a broader range of hardware in a more consistent way. So whilst you could try it again today and I can guarantee it's better than the last time you used it, if you want a DIY system instead of a Mark II - I'd suggest adding a reminder to check it again in a couple of months once these bigger changes land.
