Pronounceology uses these sources, or online dictionaries, to search for your terms. It uses a “cascading” style to search, meaning it looks to bring you one result. This means the order of your sources will be the order it looks – if it finds your search term in the first or second source in the list, it will not look for that term in the others.
In the example below, Pronounceology starts with Merriam Webster, then goes on down the list. Make sure turn off any sources you don’t want to use.
