Voice of All Things

The ability to hear the "Voice of All Things" is a unique power that only a few people in the world posses.

Overview
This power grants the user the ability to it's user to understand and gain information through inanimate objects and creature who do not speak the same language. So far, this seems to be an ability gained from birth.

A somewhat related ability that not all users share is the ability not just to understand, but also communicate with different species.

Some people use this ability to read the Poneglyph.

The Three-Eye Tribe is rumored to have access to this ability through utilizing the power of their third eye.

Usage
Those who use this ability have been so far mostly shown to be unaware of its usage or even its existence.

When Roger first crossed the Red Line he could hear the Sea Kings voices, but he did not knew who was it that talk to him on the sea floor. However, by the time he reached the end of the Grand Line, and started his search for Raftel, he could hear the voice of Zunisha and that of Big Mom's Road Poneglyph.

Princess Shirahoshi has this ability from birth, and used it by the early age of six years old accidentally. Ten years later, she uses it again and learn to control her power over the Sea Kings. Her father, King Neptune, reference to it as "the awakening of the power that can destroy the world".

Kozuki Momonosuke could hear a voice from the Whale Tree, and also Zunisha's cries for help, and he said it gave him a headhack. After failing to do so himself, Luffy who could also hear Zunisha, told Momonosuke to try and talk back to the elephant. When the member of the Ninja-Pirate-Mink-Samurai Alliance went their separate ways, Momonosuke stayed on Zou in order to talk to Zunisha.

Luffy have been shown to be able to hear and understand animals.

It have been said that Kozuki Oden could also hear Zunisha's voice but not talk back. He could also hear a voice from the Whale Tree on Zou.

The Three-Eye Tribe are said to be able to use this ability, however mixed blood members might not necessarily be able to use it at all.
