Centres that have phonetically transcribed resources:

* MPI: [http://hdl.handle.net/1839/00-0000-0000-0003-467F-7@view Corpus Spoken Dutch], [https://corpus1.mpi.nl/media-archive/MPI_CGN/Regions/Dutch_regions/Overgangsgebied/Gelders_Rivierengebied/Annotations/fn000002.bpt sample], using SAMPA, example: {{{hoxst@}}} ("hoogste")
* BAS: several corpora, eg [http://hdl.handle.net/11858/00-1779-0000-0024-7040-7 PhatSessionz], [https://clarin.phonetik.uni-muenchen.de/BASRepository/Corpora/PHATTSESSIONZ/3945/AAA394501_0.par sample], example: {{{tsv'aI}}} ("zwei")

Idea: using a common CQL index (e.g. "phonetic") to allow searches in all the phonetically transcribed material
