Some audio devices have power management system which disables the device when it doesn't play any audio. This makes NVDA less responsive. When you press a key and NVDA wants to say something, you need to wait few miliseconds because the device needs to initialize, and after that play the sound, in this case speech synthesys. This also applies when you for example spell the statusbar or titlebar - spaces between characters are longer. The solution is really simple, Play silence. to the device all the time or somehow make it still active. When you run audio player such as winamp, NVDA is really more responsive, also when you pause the player. I think that we should integrate to NVDA something which will make the soundcard active all the time when NVDA is running. In most situations user can not disable this power management. In older soundcards, there was a comfig file or specific driver related dialog where this was possible, but nowadays it seems that mostly user can't do nothing about it.
