P-base is a database of several thousand sound patterns in 500+ languages, which I collected for my dissertation. There is a downloadable version available, and a browser-based version under construction.
The original Python/Tk version can be downloaded here.
P-base 1.92 for Windows (also runs in Linux and Mac OS under Wine)
P-base 1.93 binary for Linux (64-bit)
To run the program, unzip/extract and click on "pbase1.92.exe" in the pbase1.92 folder (Windows) or type "./pbase1.93" (Linux).
P-base 3Segment inventories can be searched on-line, but searching and browsing sound patterns will require downloading the original Python/Tk application until my RAs and I finish converting the sound pattern entries to the new format. The new SQL-based P-base interface was developed with Anthony Brohan from Queen's University. The P-base database can be cited as Mielke, Jeff (2008) The Emergence of Distinctive Features. Oxford: Oxford University Press.
Visualize phoneme frequencies
These are IPA charts in which area represents the crosslinguistic frequency of IPA symbols, according to the segment inventories in P-base. The figures were created using the Cart program, which is used to make density-equalizing maps like in The Atlas of the Real World. The density-equalization algorithm is described in Diffusion-based method for producing density equalizing maps, Michael T. Gastner and M. E. J. Newman, Proc. Natl. Acad. Sci. USA 101, 7499-7504 (2004). For these figures, I made IPA charts with density information based on the frequency of each symbol in phoneme inventories in P-base and used Cart to warp the grid lines to make area reflect frequency, and then plotted them in R.
|Vowels by length and nasality|
|Consonants by labialization and palatalization|
|Consonants by laryngeal parameters|
|Languages with particular segments|
