# Custom Vocabulary

> Teach Utter your unique words, names, and terminology

Add words you use often so Utter transcribes them correctly the first time.

Custom vocabulary helps Utter accurately transcribe words it might not recognize by default, such as names, technical terms, brand names, or industry jargon.

## Why Use Custom Vocabulary

<CardGroup cols={2}>
  <Card title="Names" icon="user">
    Colleague names, company names, product names
  </Card>

  <Card title="Technical Terms" icon="code">
    Programming terms, acronyms, specialized jargon
  </Card>

  <Card title="Brand Names" icon="building">
    Products, services, or companies you mention often
  </Card>

  <Card title="Unique Words" icon="lightbulb">
    Internal terminology, project codenames, abbreviations
  </Card>
</CardGroup>

## Adding Custom Vocabulary

<Steps>
  <Step title="Open Settings">
    Click Utter in the menu bar > **Settings**
  </Step>

  <Step title="Go to Vocabulary">
    Navigate to the **Vocabulary** section
  </Step>

  <Step title="Add Words">
    Click **Add Word** and type your custom term
  </Step>

  <Step title="Save">
    Press Enter or click Save
  </Step>
</Steps>

**What to expect:** New recordings should use your saved spelling for those terms.

**If that did not work:** Add alternate spellings or pronunciation hints for terms that still come out wrong.

## Best Practices

### Spelling Matters

Enter words exactly as you want them transcribed:

| You Say      | Without Custom   | With Custom Vocabulary |
| ------------ | ---------------- | ---------------------- |
| "Kubernetes" | "cooper netties" | "Kubernetes"           |
| "OAuth"      | "oh auth"        | "OAuth"                |
| "NextJS"     | "next jay ess"   | "NextJS"               |

### Include Variations

Add multiple spellings or variations if needed:

```
PostgreSQL
Postgres
```

### Add Context (Advanced)

For words that sound like common words, you can add pronunciation hints:

```
Supabase (sounds like "super base")
```

## Tips

  Start with the words you use most frequently. You can always add more later as you notice transcription errors.
</Tip>

<Note>
  Custom vocabulary improves over time as you use Utter more. The system learns your speaking patterns and context.
