Language analysis for the determination of origin, usually shortened to LADO, is used in asylum procedures in many countries when a person’s claimed origin is in doubt and documents are missing or unreliable. For solicitors, caseworkers and tribunal members, the question is rarely “what is LADO?” but “how much can I rely on this report?”. This guide explains what a sound analysis looks like and offers a practical checklist for reading a report.

What LADO does, and what it does not

In a LADO analysis, a specialist examines recorded speech for features that vary by place and community: pronunciation, grammar, vocabulary and expressions. The aim is to identify the country, region or community in which a person was socialised, in other words where and among whom they learned to speak. Our language analysis page explains the process in more detail.

The key word is socialised. Language analysis cannot by itself determine national origin, nationality or citizenship, which are legal rather than linguistic matters. What it can do is indicate the country or region of socialisation. Borders do not follow dialect boundaries, and many communities live on both sides of them, so the same variety can be heard in two or more states.

That is why nationality is better treated as a separate question. At SILA Linguists, nationality assessment combines the person’s language with their knowledge of national institutions and the documents in the case, and works alongside LADO rather than replacing it.

What a sound analysis looks like

A reliable LADO report rests on a small number of principles that any reader can check. In our work, and in the reports we review, we look for these:

  • Trained, qualified analysts. The analysis is carried out by people with linguistic training as well as first-hand knowledge of the variety. The expertise of a native speaker is not the same as the expertise of a linguist, and a sound report draws on both.
  • Appropriate certainty. Conclusions are expressed with qualitative degrees of certainty, not with spurious precision such as a percentage.
  • Socialisation, not citizenship. As above, the analysis addresses where a person was socialised, not their nationality.
  • Attention to the speaker’s history. Movement between countries, time in camps or cities and contact with other communities all shape how a person speaks, and must be taken into account.

Language analysis is a form of forensic analysis that calls for skills beyond fluency. Trained native-speaker analysts bring an ear for the variety; qualified linguists bring method, transcription skills and the discipline of testing alternatives. At SILA Linguists, native-speaker analysts work under the supervision of qualified linguists, so that both kinds of expertise shape every conclusion and every limit is stated openly.

Used in this way, LADO can be a valid form of assistance in the asylum process, provided its limits are carefully evaluated and the report says plainly what the speech can and cannot show.

How a report is weighed

A LADO report is expert evidence, not a decision. The analyst talks and listens to the person speaking in their own language and dialect, or works from a recorded interview, and produces reasoned conclusions about their place of linguistic socialisation. The decision maker then assesses the weight to be given to the report in each case, alongside the interview, the documents and everything else on file. That is why the way a report is produced matters as much as its conclusion: a decision maker can only give real weight to reasoning that is set out openly, supported by examples from the recording and open to testing by the other side.

A checklist for reading a LADO report

When you receive a report, whether it supports or questions a claim, these questions help you judge its reliability:

  1. Who did the analysis? Are the analyst’s qualifications and experience stated? Is there a qualified linguist responsible for the conclusions?
  2. What data was used? How long was the recording, how was it obtained, and what was its quality? Was the speech spontaneous or a short scripted exchange?
  3. Which features are described? Does the report give concrete examples of pronunciation, grammar and vocabulary, with transcriptions, rather than general impressions?
  4. Were alternatives considered? Does it explain why the speech fits one region better than plausible others, including neighbouring regions across a border?
  5. Is the speaker’s history addressed? Does it consider migration, time in other countries and contact languages that could explain unexpected features?
  6. Is the certainty appropriate? Is the conclusion expressed in measured, qualitative terms, with its limits stated?
  7. Does it stay within its field? A linguistic report should not comment on credibility in general or on matters outside language.

A report that answers these questions clearly can be tested and relied on to the appropriate degree. One that does not may need a second opinion.

Second opinions and counter-reports

Where a report is disputed, an independent analyst can review the original recording and reasoning and produce a counter-report. This is a normal part of fair proceedings: it tests the method, not the person. A good counter-report follows the same standards as a first report: transparent data, explicit features, alternatives considered and appropriate certainty.

Language analysis and supporting services from SILA Linguists®

SILA Linguists® provides language analysis for the determination of origin, age assessment reports and nationality assessment for immigration authorities, solicitors and barristers in the UK, North America, Australia, New Zealand and beyond, including second-opinion reports. Our analysts are native speakers who hold formal credentials in linguistics or forensic phonetics, work under quality control and peer review, and follow recognised professional codes of practice. Each report documents the data, the analytical steps and the interpretation, and discusses alternative explanations and uncertainty: the points the checklist above asks you to look for.

A LADO case rarely ends with the report. Our transcription service produces accurate, time-coded transcripts of recorded interviews, with translation where needed, and our document translation team provides certified translations with a signed statement of accuracy accepted by UK authorities. For client conferences, hearings and appointments, we supply face-to-face interpreters, telephone interpreting and video interpreting, matched by language, dialect and, on request, gender, across 350+ languages and dialects. Our immigration and asylum and legal pages explain how these services fit together.
