LADO meaning in Governmental ?

Language analysis for the determination of origin (LADO) is an instrument used in asylum cases to determine the national or ethnic origin of the asylum seeker, through an evaluation of their language profile. To this end, an interview with the asylum seeker is recorded and analysed. The analysis consists of an examination of the dialectologically relevant features (e.g. accent, grammar, vocabulary and loanwords) in the speech of the asylum seeker. LADO is considered a type of speaker identification by forensic linguists. LADO analyses are usually made at the request of government immigration/asylum bureaux attempting to verify asylum claims, but may also be performed as part of the appeals process for claims which have been denied; they have frequently been the subject of appeals and litigation in several countries, e.g. Australia, the Netherlands and the UK.
