If by highest you mean loudest, it was Hitler that has the highest recorded voice in history.
Dennis Mecham does the voice for when auditions for the part came, he had the loudest roar.
blue whales are the loudest. their voice can reach up to 188 decibels and can be heard from hundreds of miles away in water.
Depends how you're using it. If you were talking about a man who owns lots of parakeets, and you wanted to talk about the parakeet who chirped with the highest volume, then you could quite legitimately say "his loudest parakeet". If you were talking about a young boy in a school play who was too shy to be heard during rehearsals but in the performance he found his courage and his voice, you could say "he spoke his loudest" or more accurately "he spoke in his loudest voice". Yes it makes sense, if you're using it in the right context.

Mariah carey has a very loud voice but she can also silg in many different ways.
The noisiest animals, in water, are Blue Whales. The noisiest animals, on land, are the howling monkeys (ALOUATTA) of central and South America. The howling monkeys can be heard 16 km/ 10 miles away and blue whales can be heard 850 km/ 530 miles away.
No it isn't the same thing, yelling is louder than shouting, shouting is raising your voice quite a bit but yelling is raising your voice to the loudest it can go.
Now the Animals Have a Voice was created in 2004.
If you want the largest sound made by an animal that animal is the Blue Whale.
