Names, product terms, and jargon are the hardest part of dictation. Most tools do not let you upload a custom dictionary. That does not mean you have to type every hard word by hand.
Say the word slowly the first time
Speak the term one syllable at a time on the first mention.
Then say it normally for the rest of the session.
Fix the first mention on screen after paste.
Use a paste dictionary
Keep a text file of your hardest terms with correct spellings. After dictating, open find and replace in your editor and swap common misfires for the correct term.
Spell out sparingly
Only spell out truly hard proper nouns. Spelling breaks flow and slows the session. Better to accept one bad guess and fix it later.
Save time with autocorrect
Add your hardest terms to your OS autocorrect.
Type a short code, get the full term on replace.
Combine with dictation for the fastest fix.
Make the workflow survive a bad day
A voice workflow is only useful if it still works when you are tired, distracted, or on a noisy train. The way to prove handle names and jargon in voice typing is real is to use it on a day where you do not feel like it. Keep the mic close, speak in short sentences, and accept that the transcript will be uglier than usual. The point is not a perfect first pass — it is that you got the thought out of your head and onto the page before it evaporated. A rough voice draft on a bad day still beats an empty document on a good one.
Where Zahvox fits after the raw capture
Zahvox is the careful second pass that turns a rough voice draft into something you would actually send. Paste the transcript into the free tool at /tool, tighten the wording, fix the shape of the sentences, and copy the result back into wherever it needs to live. That two-tool loop — raw capture anywhere, careful edit in Zahvox — is the whole workflow, and it stays the same whether the source was a laptop, a phone, or a meeting.
