The despair when your niche interest appears has a brief appearance on social media but you miss it by half a day because of time zones / your own kin-ties get up at 4am so you go to bed early 😅

Please check out kinbank.net for all your kinship terminology variational needs!

Short answer - it's complicated 🤣
Longer answer - the intersection of genealogical, cognitive, linguistic, and cultural variation alongside individual differences in family make-up and personal relationships makes it complicated 🤣🤣

Solomon Island Pijin has increased its first-language speaker pop. by 8,281.85% since 1976, according the Solomon Island Census. In 1976, 1,212 people listed their first language as SIP, but in 2019, that number had increased to 101,588. An incredible transformation of the linguistic environment.

Lucy sings this to our daughter all the time! Is it online or in person?

Thanks to my co-authors for doing the hard work of collecting, building, and cleaning the corpus. More to come on the corpus as a whole.

Thanks to all the speakers of Bislama and Tok Pisin
who contributed to this corpus, as well as the community members who facilitated its construction.

I will be presenting these results at the 63rd Conference for the Association for Computational Linguistics in Vienna tomorrow in the 10.30 am - midday slot

Unfortunately for me, it will be a remote presentation, but I am envious of all the attendees! 🇦🇹

NEW PAPER: English acoustic models perform well in the forced alignment of two Pacific Creoles (Tok Pisin 🇵🇬 & Bislama 🇻🇺). We show that applying existing research to low-resource languages can help speed up their study, particularly for English Creoles.

The Scientific and Cultural Cost of Convenience Sampling in the Face of Rising Language Endangerment: Highlighting the Role of Language Acquisition Abstract. We live in an unprecedented era of language endangerment and loss. In the midst of this crisis, it is becoming more and more evident that the psychological and cognitive sciences know very l...

The scientific loss of languages is overshadowed by the loss of cultural knowledge. Unlike biodiversity, preserving past conditions isn’t viable or desirable. The best way to address this challenge is through coordination between governments, academia, and, most crucially, engaged communities.

Despite growing concern over diversity and more research on child language acquisition, the number of unstudied languages remains steady. Just two new languages are studied each year, while many more stop being passed to children—soon, more will be lost than studied.

Not only are child language studies focused on institutionally similar languages and capture only a narrow range of phonetic and grammatical diversity. About 10% of this diversity can’t be studied in child learners, as those languages are no longer being acquired by children today.

87% of unstudied languages are written, vigorous, or threatened. Children learning these languages experience informal transmission of language. 48% of studied languages are National languages, entrenched throughout the community. Children are unlikely to learn these languages the same way.

NEW PAPER: Linguistics has long debated the scientific cost of narrow sampling, but growing language endangerment makes this debate urgent. We compare studied and unstudied languages in child language acquisition to assess how narrow sampling limits our understanding
