1) Press the button before you start speaking and don't release the button until you are done.
We've noticed that some customers let go of the button a split-second too early, and hiku ends up cutting off the last syllable. For best results, we recommend being intentional to hold the button down for about a half-second+ after you finish speaking.
2) Talk into the microphone, about 4-5 inches away is ideal.
Gen 2 devices have 3 small holes near the charging port - that's where the microphone is.
Gen 1 devices have a very small microphone hole closer to the lens.
