According to the study of Bainto and Esquejo

According to the study of Bainto and Esquejo (2010) the researchers came up with the following significant data that texting had diminished the spelling proficiency of the students. The researcher also conclude that texting habits affect the declining spelling proficiency of students, text languages often confuse the students with the correct spelling of the words leading to usually misspelled words.
The cellular phone industry widely caters to the younger market. The study shows that most of the respondents aged 16 to 21, majority of them 17- to 18-year-olds, have cellular phones (95 percent, DLSU; 71 percent, UPLB). Most of them are prepaid phone users, with an average spending profile of P400 to P500 (Laurilla, n.d.).
The study of Laurilla shows that students admit to abbreviating (89 percent, DLSU; 100 percent, UPLB), citing convenience as the number one reason for doing so. Other reasons given: it is the “in” thing or fad, or that they do not know the spelling of the words.
Another research on the use of the shorthand method of texting by Banton et al. (2010) said that same assumptions rose about the negative claims on text messaging. Banton with his group researchers conducted a study by giving out a pre-survey on those students who were cellular phone owners and non-owners and their daily time allotment for cellular phone use. After that was the spelling and grammar tests given the 3rd year high school students of St. Paul’s School of Ormoc Foundation Inc. The research resulted with the following: Students who had greater time allotment for text messaging had lower average scores compared to those who were not frequent texters at all. Among cellular phone owners, those who were frequent users of shorthand method of texting appeared to have poorer scores in both spelling and grammar tests. (n.a., 2011).
As conducted on a study by Shane Snow, the Philippine is still considered the Text Capital of the World. With the constraint of Short Messaging System (SMS) of 160 characters or less to send a message, people learned how to shorten what they wanted to say that is now referred to as ‘text speak’. One simple way of shortening a message is by taking out all the vowels; however, this does not work for some words because it gives out an ambiguous feel for words that have similar consonant sequences. Phonetics or how the word sounds like also plays a role in shortening messages for Filipino texters (Chua, 2011).
