Loud enough to be heard across a room ! Latest Version III Sound Chip. Approximately 20% Louder than prior versions. Excellent for heavy sleepers. Provides instant audio feedback in a very clear and LOUD female human voice. And not only does it announce the time when the alarm goes off, but you can also simply tap the large snooze button for the time any time you like. Or, set it for an automatic hourly time announcement (5 am till midnight). Voice: SPANISH. See my other listings for English if you prefer that instead.
