language detection using matlab gui

I want to create an application that recognizes the language of a text so that when the user inputs the text clicks on the pushbutton it displays the language . Please how do I go about it. What should the code look like.

Is the text by image, or is it by character? If it is by character then is it ASCII, or one of the ISO-8859-*, or is it Windows Codepage 1592, or is it UTF-8, or ... ?

How big are your wordlists for each language? How good are your routines to infer suffixing for parts of speech? Or infer conjugation of verbs? Or infer gendering of verbs or nouns? How good are your routines for inferring changes in word form depending on the relative social status of the speaker and the person being spoken to? How much leeway are you going to allow for spelling mistakes?

Consider the word "a". What language is it? How do you know?

Language recognition is very complicated, and there are multiple possible approaches to achieve it (none of which are perfect). You should start by doing some research into different possible methods of doing this, deciding which one is appropriate for your task and level of experience, and then ask us when you have specific implementation problems.

When I use Google Translate, it is more common than not that Google suggests at least three different languages for a text.

Sometimes language is unambiguous, such as Japanese written in katakana, or Korean written in hangul, but, for example, what might look like Chinese might instead be Japanese kanji, and what might look like Greek might be one of the languages that developed in areas where the Greek Orthodox Church was prevalent.

It can be difficult for an outsider to see the difference between the Iberian languages (e.g., Spanish, Portuguese, Galacian, Catalan.) Google Translate often has problems telling them apart on shorter texts with more dialect.
