For our paper "Warning words in a warming world : Central bank communication and climate change" (Accepted in the European Economic Review), my co-authors and I compiled the most comprehensive collection of central bank speeches ever collected. This data is now open access and will be updated regularly.
CBSpeeches contains 35,487 speeches, drawing on the BIS dataset (18,045 speeches), augmented with a systematic scraping of central banks' websites (15,435 new speeches) and archival work (2,007 additional speeches). Among these new speeches, 5,347 were provided in a non-English language and were translated using Microsoft Translation services.
