Whispering Wind

You send a message or sound on the wind to a designated spot. The whispering wind travels to a specific location within range that is familiar to you, provided that it can find a way to the location. (It can't pass through walls, for instance). A whispering wind is as gentle and unnoticed as a zephyr until it reaches the location. It then delivers its whisper-quiet message or other sound. Note that the message is delivered regardless of whether anyone is present to hear it. The wind then dissipates. You can prepare the spell to bear a message of no more than twenty-five words, cause the spell to deliver other sounds for 1 round, or merely have the whispering wind seem to be a faint stirring of the air. You can likewise cause the whispering wind to move as slowly as 1 mile per hour or as quickly as 1 mile per 10 minutes. When the spell reaches its objective, it swirls and remains in place until the message is delivered. As with magic mouth, whispering wind cannot speak verbal components, use command words, or activate magical effects.
 

You send a brief message or sound on the wind to a location familiar to you within range. The wind travels by natural means, following open airways and pathways—it cannot pass through solid barriers or airtight enclosures.   The wind carries a message of up to 25 words, a simple sound (such as a chime or whisper) lasting up to 6 seconds, or a faint stirring of air as harmless ambient noise.   The wind moves at a speed you choose, between 1 mile per hour and 1 mile per 10 minutes.   When the wind reaches the destination, it lingers briefly and delivers its message, whether or not anyone is there to hear it. It then dissipates harmlessly, ending the spell.   The wind cannot speak command words, verbal components, or activate magical items. It is not affected by spells such as Silence, though it cannot pass through magical barriers that block wind or air movement.   At Higher Levels. When you cast this spell using a higher level spell slot, increase the maximum word count by 10 words for each slot level above its base level.
