Dialogue blip

From VNDev Wiki

A dialogue blip is a sound effect that plays as text appears in a text box, generally when a character is speaking. These sounds are usually electronic “blips”, but may also be other sound effects (like a typewriter) depending on the game, character, or scene. The Ace Attorney series is one example of its use in a visual novel. Dialogue blips may be made of voiced segments (such as the use of Animalese and Bebebese in the Animal Crossing series), but isn’t the same as partial voice acting/barks.
