Answers to Questions (FAQ)
What is language recognition? (Definition)
A language is a system of signs (characters) that enables communication between people. Language recognition (dialect or lang detection) is a process that aims to determine the language in which a text is written. It uses algorithms and statistical models to analyze the linguistic characteristics of the text and assign a specific language to it.
How to recognize/identify the language of a text?
Language recognition is mainly based on the analysis of the frequencies of words, characters and n-grams (combinations of n consecutive characters) present in the text. This data is then compared to the characteristics of the different languages to determine the most probable.
— A quick method is to detect/identify/recognize common words in a language.
Example: In English a, to, of, etc., in French, de, la, le, un, et
— Count rare characters (or missing ones) to discriminate some foreign languages
Example: In English, the letter j is rare, in French, the letter w is rare and limited to words imported from other languages
— Look for language specific characters/signs as diacritics
Example: In Spanish, the ñ (tilde n) appears often, in French, accent letters such as â,ç,è,é,ê,î,ô,û,ù are used, etc.

How to recognise a spoken language?
Language recognition processes written texts to determine the language used, while language in speech detection is concerned with identifying spoken language in real-time audio or speech. It's a much different process that requires voice recognition technologies. dCode does not offer this feature.
