Writing in voice?

[unnbrellas]

I normally have a slight southern hint to my posts, but that's because it's how I would say it.

I do this so often! xD

Where I come from, the second most common language is full of "V's" And "W's" but they're switched around.
So I often say "Vat are you doing?" Instead of "What are you doing?" 
And I use "Ja" a lot instead of "Yes"

I always talk in a high-pitched voice and often change words.

Mommy turns into, "Muma" and Daddy turns into "Da"

I talks childish at times and will sometimes miss some vowels, or L will go away completely, they don't even turn into a W. When she is crying she often misses some vowels and they turn into squeaks, or sniffles, because I imagine her talking squeaky when she is crying, sort of like Simba. I also repeat words sometimes. It's part of being a cub, DON'T QUESTION IT!

When I am eating, or something like that where my mouth is holding something or I buried my head in the dirt, my voice turns muffled. You know, "Whgy mef?" meaning, "WHY ME?" xD or, "Ig wanged ZEBAG!" meaning, "I WANTED ZEBRAH!" xD

I do a lot of voices, depending on what I'm doing. Hope this answers your question, lawl.

Aye, (punspunspuns) I tend to bring some of the 'RP' into my usual OOC speak. I'll do the 'y'all' or the ''bout' as well. I do have an accent irl, but I'm sure I don't sound like how I type.

I don't think it's so much a/your 'voice' when you use RP terminology - more a habit.

We do things like...

*snarls*
*grabby paws*
*hisses*

...As well, or at least I do and many of those I have met do likewise. This is not something I do irl (ornotoftenanywaydontjudge).

It CAN get annoying when someone's OOC speak is full of an IC-like tendency. But honestly, I don't think it's a voice so much as habit, even a subconscious urge to practise for when IC times occur.
