Adding Dialogue Beep SFX

Dia:
    "Dialogue voice beep often used as
    substitute for voice acting in video games."
:
    "Especially in the older titles
    and smaller budget productions."
:
    "Although not really used in modern titles anymore,
    there's many indie games that still use this today."

TL;DR

Play the dialogue beep audio with the DialogueLabel's character_drawn signal.

Add the dialogue voice beep audio file to your project. In this article, we'll use one of the sound effect from Text/Dialogue Bleeps Pack by dmochas .
Add AudioStreamPlayer node, attach the beep audio file to it, and reference it as beep_player variable.
```
@export var beep_player : AudioStreamPlayer
```
Connect the signal character_drawn from DialogueLabel to method _on_dialogue_label_character_drawn().
```
func _on_dialogue_label_character_drawn():
    pass # Replace with function body.
```

On the signal method, play the audio from the beep_player using play(). Only if its not already playing.

func _on_dialogue_label_character_drawn():
    if not beep_player.playing:
        beep_player.play()
