Put it first in an edit as the opening hello, then follow it with a WhatsApp Message sound to signal a reply is coming, and keep a Hola Tururururu greeting nearby for a second, more playful hello later in the same chat.
About this sound
This is a short spoken greeting in Spanish, lasting about two and a half seconds, in which a friendly voice says good afternoon to friends of YouTube. It feels warm, casual and welcoming, like the start of a chat with people you already know. The relaxed tone makes the hello feel personal rather than formal, and easy to drop into a conversation.
