Sometimes a transcription engine may mistake one word for another that sounds similar. If you notice the same word being consistently transcribed incorrectly, you can use a Substitution dictionary to automatically replace the incorrect transcription with the correct term.
Creating a Substitution dictionary
Before you can use a substitution dictionary, you'll need to create one:
- Open the Substitution dictionaries page from the sidebar.

- Click New substitution dictionary
- Enter a name for the dictionary and select the language it will apply to
- Add your substitution rules by completing the Find... and Replace with... fields, then click + Add rule
- Click Create dictionary to save your dictionary

Using a Substitution dictionary with Timbra
Once your substitution dictionary has been created, you can apply it to a Timbra project:
- Create or open your Timbra project and navigate to Languages & Settings
- Under Source language settings, locate the Substitution dictionaries option
- Click + Add and select the dictionary you want to use

- The selected substitution dictionary will be applied during the final stage of the transcription process, automatically replacing any matching terms according to the rules you have defined
Substitution dictionaries are particularly useful for correcting recurring transcription errors involving names, brands, product terminology, acronyms, or other words that are frequently confused by speech recognition engines.
