Speech Recognition
Turning spoken words into text. It underpins voice search, dictation and call transcription, and it now handles accents and background noise far better than it used to.
Related terms
Human-in-the-Loop
Keeping a person in the decision, either approving what the AI produced or handling the cases it flags. The usual sensible middle ground between doing everything by hand and trusting a machine completely.
Hallucination
When an AI states something false with complete confidence — an invented price, a policy you never had, a product you do not sell. The usual cause is that the correct fact was not available anywhere it could read.
BreadcrumbList Schema
Markup describing where a page sits in the site’s hierarchy. It helps both search engines and assistants understand that a page is a service under a category, not a stray document.
Google-Extended
The robots.txt setting that controls whether Google may use your content for Gemini and AI Overviews. It is separate from ordinary Google Search, so you can allow one and refuse the other.
Prompt Engineering
The craft of writing instructions that get reliable results from an AI — being specific, giving examples, saying what to avoid. Less mysterious than it sounds, and mostly the same skill as briefing a new colleague well.
Tool Use
An AI reaching outside itself to do something it cannot do alone: run a search, do arithmetic reliably, read a live page. Nearly every useful assistant depends on it.
