Effect of pronunciation on spelling

Pronunciation is defined as "The way words are made to sound when spoken". As you would have noticed, most people consider their pronunciation the correct version. Well, the effect of accent, schooling, and many other factors affect the pronunciation of a person. But what hapeens when a person with wrong pronunciation writes that word? In all likelyhood he will write it in the wrong way.

Consider the modified spelling of the word "tomorrow" as "tommorow", When i gave this query to google the first two results i got were Notes of an iraniangirl and tommorow's muslims. Most of the other results were from disscussion forums, which can be ignored as typos. The reasoning here is that Middle eastern pronunciation seems to give this effect of adding another "m", which translates into a spelling difference. It has to be noted here that it is not a mistake, but rather an error of ignorance. This may be a significant factor in the creation of new words. I am in search of some online documentation for the same.

The modified spellings in differrent countries can easily lead to modified meanings as well. So this can be a major factor in the creation of newer words. I call this phenomenon the "tomorrow effect", for the want of a better word to describe the same.
