At about 16.2 seconds, the clip is long enough for the repeated call to build, though you can trim the ending for a quicker interruption. Download the MP3 to keep a local copy and trigger it offline from a soundboard or media player. For a ringtone, use the full file so the voice has time to repeat; for a notification tone, cut a shorter section. Because the delivery is forceful, lower it slightly when placing it over speech, especially if the surrounding audio is already loud.
