It is both, actually. There was improvement with the sound when the witness placed the microphone higher up, but it seems that the device itself does not allow for clear sound. The last option we can try, perhaps, is for the witness to put the microphone further away and up to see if that works, but really, it's a matter of quality. It's not just a question of having the text.
