Word replacements

Word replacements rewrite text after recognition finishes — for fixed errors, brand spellings, and filler words.

Open

• Settings → Text processing → Word replacements
• Menu bar entry
• Deeplink: voicehotkey://word-replacements (see Deeplinks)

Rule fields

Field	Meaning
Original	Match text; comma-separated variants OK
Replacement	Result (empty = delete)
Regex	Optional; $1 groups
Timing	Before processing / After / Both (relative to LLM polish & translation; if no AI runs, rules still apply once to the raw transcript)

Matching is usually case-insensitive; literal rules match on word boundaries where possible. For regex, add \b yourself.

Examples

Original	Replacement
raycast, reycast	Raycast
air pods	AirPods
\b(um|uh)\b (regex)	(empty)

Difference from recognition dictionaries

• Engine context / prompt: helps ASR hear it right the first time.
• Word replacements: an output-level safety net, works with every engine.

You can use both together.
