Did you know: sperm whales communicate with codas, short patterns of clicks, and whales that share
a coda dialect form a “vocal clan”. Across the Pacific, researchers have
identified seven clans, each with its own dialect.

A man who had arrived in the UK said he came from Daraa, a city in southern Syria, which he had left at 16 (Matras, 2018).
| English | Applicant | Syria (Daraa) | Egypt (Cairo) |
|---|---|---|---|
| here | [hoːn] | /hoːn/ | /henaː/ |
| don’t go | [laː truħ] | /laː truħ/ | /maː tiruħ/ |
| two sons and a daughter | [waladeːn uː binit] | /waladeːn uː binit/ | /waladiːn wa bint/ |
| like this | [heːk] ~ [kida] | /heːk/ | /kida/ |
| teacher (f.) | [mudarrísa] | /mudárrisa/ | /mudarrísa/ |

Did you know: in the Pacific, the “identity codas” that
mark a clan are more distinct where two clans
share the same waters, much as human groups mark their identity more
strongly where they meet.

Without papers, two kinds of evidence can show where someone comes from: their body (for example medical evidence of torture or injury) and their story, including the way they speak.
Linguistic Analysis in the Asylum Procedure (LAAP, also LADO, LOID or LingID) analyses a claimant’s speech for features of language, dialect, grammar and vocabulary, as in speaker profiling, to test whether they grew up where they say.
Figures as reported in Leemann et al. (2024). The Netherlands runs LAAP in about 10% of asylum cases, Switzerland 600–1,000 interviews a year. UK figure from a recent survey (Hoskin, 2022).
In the Netherlands and Switzerland, about half of the reports go against the claimed origin. In the UK, about 5% do.
In some countries, including the Netherlands and the UK, a rejected applicant can ask an independent counter-expert to assess the report. The counter-expert works for the asylum seeker, re-analyses the recordings, and may make new ones.
Judges only take the counter-report seriously if it raises strong doubt about the original.
Did you know: off Dominica, the “1+1+3” coda, three
evenly spaced clicks after two slower ones, has been the most common
coda for at least 30 years, and has only ever been recorded in the Caribbean.

In 2004, 19 linguists from the US, Europe and Australia drew up guidelines for LAAP (LNOG, 2004). Among their points:
The guidelines also set out who should do the analysis, and how to state the result:
Professional bodies have endorsed the guidelines, but they say nothing about how to run an interview, analyse it, or write a report.
From the opening of a LINGUA interview, translated (Hubbuch, 2019):
C: I do, I do, but who are you? I: Well, how shall I put this… I am an independent expert. C: And where are you? I: It doesn’t matter. C: Mhm. Yes it does.
The interview that followed was successful. In most cases, LAAP is reported to be straightforward (Hubbuch, 2019).
In the UK, a LAAP report should:
Not all agencies follow these principles. Some reports do not make clear how the interview was run or how the conclusion was reached.
An applicant said he came from the Central African Republic and spoke Sango, Gbaya and French. Asked to translate simple French words, he could not speak Sango or Gbaya fluently (Cambier-Langeveld, 2018).
| English | French | Applicant | Sango |
|---|---|---|---|
| head | tête | [sətok] | /li/ |
| fish | poisson | [gwɛk] | /susu/ |
| I | je | [ɲi] | /mbi/ |
| dog | chien | [gwi] | /mbo/ |
His words matched Moghomo, a language spoken in Cameroon.
Did you know: sperm whale codas vary in timing with the
conversation and sometimes gain an extra click. Researchers call these
features rubato and ornamentation, and found
that they combine with rhythm and tempo into a large inventory of
distinct codas.

Placing someone by their speech seems easy: we do it every time we meet a stranger. In an asylum interview, four things get in the way:
Simulated, following the pattern of a 2007 study described in Leemann et al. (2024): some native speakers who had lived abroad for years were rated non-native, and some learners passed as native. Nativeness is gradient.
No study can show how a Syrian teenager’s dialect changes in two years in Egypt. In such cases the analysis rests on the analyst’s judgement of the claimed circumstances.
Did you know: off Dominica, two sperm whale clans share
the same waters, but family units only associate within
their own clan, one of them with “1+1+3” codas and the other
mostly with regular codas.

In 2009, the International Association for Forensic Phonetics and Acoustics (IAFPA) accepted a role for trained native speakers working under the supervision of linguists. In practice:
The Netherlands uses native speaker analysts; in Switzerland, native speakers may take part in interviews, but only linguists analyse.
