Nidaba
I have written a database and web tools for comparing segment distributions between languages and dialects.
It can be used for finding loan words, finding elicitation items for experiments, figuring out a phonemic inventory from phonetic transcriptions, figuring out syllable structure, comparing patterns across languages, comparing different phonemic analyses of the same data, locating marginal patterns, and more.
It is currently in beta, and I would welcome any feedback. It can be found here: nidaba.co.uk
The database currently contains lexicons for Welsh, German, Greek, English, French, Irish, Cheke Holo, Dutch, Portuguese, Spanish, Sylheti, Ambel, and Matbat.
I hope to add more Oceanic, Indo-Aryan, Bantu, and Germanic languages - as well as every other language family!
If you have a lexicon for a language or dialect, be it 300 words or 30,000, please register on the website and upload it. And let me know at me at elizabeth.eden.11@ucl.ac.uk.
ACCDIST
Mark Huckvale (UCL) has written a tool for measuring accent distance based on vowel production, which has been successfully applied to different native accents of English. I am extending this to speakers of other languages.
The data from my pilot project is here
If you would be interested in collaborating on this project, please get in touch. I would like to run the experiment in as many languages as possible, and for that I need lots of non-English speakers, preferably in their home countries.
