How to Dictate Numbers, Dates and Currency Cleanly
Voice typing feels magical until you hit an invoice total, a meeting date or a price. Suddenly you are staring at "twelve dollars fifty" spelled out in words when you wanted a clean figure. Here is how to dictate numbers, dates and currency so they land formatted the way you meant, without fixing them by hand.
Key takeaways
- Say figures naturally: raw speech engines write short numbers as words, and that is normal.
- AI cleanup is what turns spoken numbers into digits, dates and currency, not the microphone.
- A custom dictionary keeps names, tickers and product codes correct next to your numbers.
- With BlaBlaType this all runs on your Mac, so financial and personal figures never leave the device.
Why dictated numbers come out messy
Speech recognition models transcribe the sounds you make, and English speech is ambiguous about numbers. "Fifteen hundred" could mean 1,500 or a time of day. "Two thousand and five" could be a year or a quantity. Short numbers below ten are conventionally written as words, so a plain transcript of "I owe you five dollars" often stays spelled out. None of this is a bug: it is the model faithfully writing what it heard.
The fix is not a better microphone, it is a second pass that understands context. Modern voice typing separates two jobs: recognition, which turns audio into words, and cleanup, which turns those words into the format you actually want. If you are still deciding on a tool, our roundup of the best dictation software for Mac in 2026 compares which apps do that second pass well.
How to dictate numbers, dates and currency cleanly
The goal with any voice to text on Mac setup is to speak once and get formatted output. Follow these steps and your speech to text will handle figures without you touching the keyboard.
Speak the value the natural way
Say "twelve dollars and fifty cents" or "the fourteenth of March" exactly as you would to a person. Do not try to spell out digits or symbols. Natural phrasing gives the cleanup step the context it needs.
Turn on AI cleanup
Enable the on-device AI cleanup pass so raw speech is rewritten into polished text. This is the feature that converts "three hundred euros" into a formatted currency amount and fixes punctuation around it.
Set a custom prompt for your format
Use a custom AI prompt to lock in one style, for example day-month-year dates or a specific currency symbol. Now every figure you dictate follows the same house style automatically.
Add tricky terms to your dictionary
Product codes, tickers and unusual names sit right next to numbers in real writing. Add them to the custom dictionary so they are recognized every time and never garbled into digits.
Because most people speak around three to four times faster than they type, getting figures right by voice saves real time across a day of invoices, notes and messages. It is the same reason dictation shines for longer writing, such as when you dictate emails on your Mac that are full of dates and amounts.
Before and after: what clean formatting looks like
Here is a realistic example. On the left is a raw transcript of spoken speech. On the right is the same passage after an on-device AI cleanup pass has formatted the numbers, dates and currency.
Notice what changed: the currency picked up its symbol and decimal, the spelled-out dates became standard dates, the quantity became digits, and the time was formatted. You said it once, naturally, and the tool did the tidying.
Getting the format you want every time
Consistency is where a custom prompt earns its keep. Dates are the classic trap, because "next Friday" or "the third" can be written many ways. By setting your preferred style once, you avoid a document where half the dates read "March 3" and the other half read "3/3/26". The same applies to currency: decide whether you want the symbol before or after the amount and let the cleanup enforce it.
For proper nouns that live beside numbers, such as a client name on an invoice or a stock ticker in a note, the custom dictionary is the reliable route. Apple's own built-in Dictation guide shows the basics of voice input, but it does not reformat figures the way an AI cleanup step does, which is the gap this workflow closes. If you are weighing how these tools are priced, our look at subscription versus one-time dictation apps is worth a read before you commit.
Speed, accuracy and privacy together
Dictating figures well is not just about tidy output. Numbers are often the most sensitive part of what you write: salaries, invoices, medical values, legal amounts. Sending that audio to a cloud server to be formatted is a real privacy trade-off. Speaking is also fast, and by most measures people talk far quicker than they type, a point the reference on words per minute makes clear.
BlaBlaType keeps both the recognition and the AI cleanup on your Mac. Your audio and transcripts never leave the device, so formatting a payroll figure or a client's date of birth stays completely private. You get the clean output without the cloud round trip. You can compare plans on the pricing page when you are ready.

Why does dictation spell out numbers instead of using digits?
Speech engines transcribe what they hear, and short numbers are often written as words. An AI cleanup pass converts spoken figures into the digit, date and currency formats you actually mean, so you do not have to fix them by hand.
How do I dictate a currency amount like twelve dollars fifty?
Say the full amount naturally, for example twelve dollars and fifty cents. With on-device AI cleanup this becomes a properly formatted figure with the currency symbol, so you rarely need to type the symbol or decimal yourself.
Can I dictate dates in a specific format?
Yes. Speak the date the way you would say it out loud, then let a custom AI prompt standardize it to the format you prefer. You can set one style for everything you dictate so dates stay consistent.
Does cleaning up numbers require sending my audio to the cloud?
No. BlaBlaType runs both speech recognition and AI cleanup on your Mac. Your audio and transcripts never leave the device, so formatting numbers, dates and currency stays completely private.
How do I dictate names, tickers or product codes accurately?
Add them to a custom dictionary so the app recognizes them every time. This is the most reliable way to keep proper nouns, jargon and codes correct alongside your numbers and dates.
