How to add extra language dictionaries

Spellcheck in the editor is powered by the spylls package. Spylls comes with the en-US dictionary from Hunspell for spellchecking. To use a different language dictionary, such as en-GB, download the desired dictionary extension from LibreOffice. LibreOffice packages all English dictionaries together as one oxt zip file (link).

Steps to add a dictionary for Windows is below but should be similar for other operating systems.

1. Download and modify the file ending from oxt to zip.

2. Open the zip file. The files are paired together, one *.dic file with one *.aff file, both with the same file name. For en-GB, this will be en_GB.dic and en_GB.aff.

3. Copy the *.dic and *.aff file into the spellcheck folder within the transcript folder if this is only for the transcript and into the plover2CAT/spellcheck folder in the Plover configuration folder if the dictionary is supposed to be available for all transcripts.

4. Re-open the transcript and select the desired dictionary for spellcheck from the dropdown list.

Uncompressed *.dic and *.aff files can be moved directly into the spellcheck folder.
