Place it at the very start of an entrance sequence, right after a door knocking sound, so the arrival is set up before the greeting begins. Follow it with a short reaction beat from your subject, and keep other greeting clips out of that opening section entirely.
Sobre este som
This is a 4.3-second voice clip built around the word hello repeated four times in a row. The repetition is the whole effect, turning a normal greeting into something playfully over the top and hard to ignore. It feels funny and exaggeratedly friendly, like someone making a big entrance out of a simple hello and refusing to say it just once.
