Custom dictionary
A personal list of words and spellings a dictation tool should prefer.
Speech models guess from sound. Names, product titles, and internal acronyms are where they guess wrong, repeatedly. A custom dictionary is the list of spellings you want instead. It does not retrain a public model. It tells this app how those words should be typed.
Murmur includes a custom dictionary alongside snippets. Add a word, dictate a sentence that uses it, and see what lands in the focused app. The steps are in Custom dictionary and snippets. We do not describe a shared team dictionary.
