Human speech of course evolved with the evolution of a voicebox.
Feargod, do you know anything about Homo floresiensis nicknamed the "Hobbit"
If your arguing against evolution you already lost the battle. It is a scientific fact and a scientific theory.
If your arguing for ID which is basically creationism repackaged because it didn't work the first time round, show any scientific proof evidence you have, don't bet around the bush so to speak.
You can say ID and that could be Aliens even. Prove it wasn't?
You have also missed a ton of evidence on evolution of the entire planet.
We breath Oxygen, because billions of years ago cynobacteria which evolved photosynthesis, created the oxygen and changed our atmosphere.
When the earth first formed it did not have the atmosphere we have today and you would not be able to breath let alone communicate. You would be dead for many reasons though not just oxygen.

The Origin of Oxygen in Earth's Atmosphere
The breathable air we enjoy today originated from tiny organisms, although the details remain lost in geologic time
"So how did Earth end up with an atmosphere made up of roughly 21 percent of the stuff?
The answer is tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen. In fact, all the plants on Earth incorporate symbiotic cyanobacteria (known as chloroplasts) to do their photosynthesis for them down to this day.
For some untold eons prior to the evolution of these cyanobacteria, during the Archean eon, more primitive microbes lived the real old-fashioned way: anaerobically. These ancient organismsand their "extremophile" descendants todaythrived in the absence of oxygen, relying on sulfate for their energy needs.

Introduction to the Cyanobacteria
Architects of earth's atmosphere
Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.

Early 'see-sawing' Earth experienced hazy shades of life
" Earth's early atmosphere fluctuated between 'organic haze' and a 'haze-free' environment similar to that of Saturn's moon, Titan, a new study has revealed.
And this switch over 2.5 billion years ago was the result of intense microbial activity and would have had a profound effect on the climate of the Earth system.
Research, led by experts at Newcastle University, UK, revealed that the Earth's early atmosphere periodically flipped from a hydrocarbon-free state into a hydrocarbon-rich state."

Can you breath Methane, or primarily natural gas?
Your breathing Oxygen right now because the bacteria called cynobacteria evolved photosynthesis and changed the earth atmosphere. Our atmosphere today is a direct result of evolution. Look it up.
The moon also formed at the same time as the earth forming.
