If SuprFlow repeatedly writes a name or acronym the wrong way, open Dictionary and add the version you want it to recognize. The installed 1.0.0 (12) screen is labeled “Custom corrections for transcription” and shows a searchable Wrong word → Correct word form with Add and Clear All controls. It is useful for surnames, company names, deal names, legal terms, and acronyms that a general speech model may miss. Test the entry with a harmless sentence before trusting it in a client document.
There is an important limit: SuprFlow passes the correct word to WhisperKit as vocabulary guidance. It does not perform a guaranteed find-and-replace of every wrong word after transcription. A Dictionary entry can improve recognition, but you still need to proofread material names and figures.
Add a correction in the current app
- Open SuprFlow from the menu bar and choose Dictionary.
- In Add Entry, put the mistaken spelling in Wrong word and the intended spelling in Correct word. For example, use fictional “Corwin Capital” if the app keeps writing “Corwin capitol.”
- Select Add. Search the Dictionary list to confirm the new entry appears.
- Dictate a short sentence that includes the term in the same context you normally use: “The Corwin Capital committee meets on Thursday.”
- Inspect the inserted text. Repeat with a second sentence and, if relevant, the exact accent, microphone, and model you use at work.
The app stores entries locally in preferences and supplies the replacement targets as a vocabulary string to the speech model. That is different from sending a custom dictionary to a hosted AI provider. If you later enable Cloud API formatting, the transcript text and formatting instructions can go to that provider; review that path separately.
Pick entries that help the recognizer
Add uncommon proper nouns and acronyms that recur often. Start with a small list: a person's surname, a firm name, a product, and an industry term. Avoid loading the dictionary with every ordinary English word; a large, ambiguous list can make it hard to tell whether an entry helped. There is no published accuracy curve for dictionary size, so use your own repeated test.
For similar-sounding names, put the word in context when testing. “Dara approved the note” and “data approved the note” are more informative than speaking “Dara” alone. For acronyms, try both the letters and the spoken expansion. If a number, negation, or date is wrong, a dictionary entry is not a substitute for checking the final sentence against your source.
If you need a guaranteed expansion, use Snippets for a distinct trigger phrase. Snippets are applied to the text after formatting and before insertion. Choose an uncommon trigger so it does not unexpectedly replace an ordinary word. The snippet guide explains the trade-off.
A five-minute acceptance test for a team
Use synthetic names and account or matter numbers. Ask three users with different speaking styles to dictate the same short paragraph before and after the entry. Track whether the intended spelling appears, whether another word was incorrectly changed, and whether the meaning of the whole sentence survives cleanup. Save the app version, model, language, and formatting mode with the result. A one-user anecdote is not evidence that an entire firm can stop reviewing names.
For a law firm, bank, or audit practice, build a controlled list with a policy owner. A local dictionary can itself contain sensitive client or matter names on a managed device; decide whether entries, backups, and device access meet the firm's rules. SuprFlow stores Dictionary entries in local preferences, so the list may outlive a single transcription.
Questions people ask
Does SuprFlow learn automatically when I fix a word?
The Dictionary uses explicit entries. Do not assume editing a pasted transcript trains the recognition model. Add a correction deliberately and test it.
Will a Dictionary entry always replace the wrong word?
No. SuprFlow uses the correct spelling to condition WhisperKit recognition. It is guidance, not a deterministic final-text replacement. Snippets perform text expansion later in the pipeline, but must be chosen carefully.
Does my dictionary stay private?
Entries are stored locally in SuprFlow 1.0.0. That does not settle the whole app's network behavior: release telemetry, account traffic, and optional hosted formatting are separate. Avoid putting confidential names into a shared or unmanaged Mac without checking device and backup policy.
