A voice that made an alien feel present
E.T. needed to sound unfamiliar without becoming hard to understand. Pat Welsh’s naturally rough, low voice gave the character a distinctive texture: its breathy rasp suggested age and effort, while her phrasing kept the alien’s words emotionally legible. The performance let audiences hear a character rather than a collection of special effects.
The sound was built, not simply recorded
Sound designer Ben Burtt treated E.T.’s voice as a layered sound. Welsh supplied its central speaking voice, which was combined with other human and animal sounds to make the result feel less like an ordinary person. That layering mattered: a voice made only from unfamiliar noises might seem strange, but could lose the warmth and personality the story needed.
The contrast helped the film’s emotional design. E.T. looks and sounds different from the children around him, yet his voice carries recognizable feelings—curiosity, fear, affection. The sound makes the alien seem otherworldly at first and understandable a moment later.
A chance discovery became part of the character
Burtt reportedly encountered Welsh while she was shopping in a camera store and recognized the unusual quality of her voice. Her contribution shows how a practical production problem can turn on a very specific human sound: instead of manufacturing every detail electronically, the filmmakers built the character around a real voice, then shaped it for the screen.
That choice helped make E.T.’s speech memorable without overwhelming the performance. The alien’s voice could be strange enough to belong to another world—and clear enough for a child in the audience to feel what he was saying.
