Nope.
But is a good help if ASI fails. If AoA shows normal values during 1G flight( and not very high AoA) the speed can not be low, provided you still think AoA information is valid. AoA-information should be very easy to check that it is not "frozen" on the same value.
Not that there most certainly was enough information to continue fly anyway.
