Hotwords

Create and enable a groupCopy Anchor Link

1. Open Settings → Hotwords, create a group, and name it.
2. Add names, products, or technical terms, such as VoicePaste.
3. Enable the group you want to use. You can save multiple groups, but only one is active at a time.

Bulk entry and weightsCopy Anchor Link

• Separate terms with English commas and press Enter, for example VoicePaste, Anthropic, Claude.
• Use term|weight for an optional weight, such as Anthropic|8. The range is 1–10; the default is 4.

Enhancement and replacementCopy Anchor Link

Configure these options in the current recognition model's parameters. Enhancement controls whether hotwords are added to polishing requests; it does not disable the recognizer's own hotword support:

• Enhancement · Auto: Prefer the model's own hotword support. If unavailable and this input uses polishing, provide the terms to the language model.
• Enhancement · Off: Do not add hotwords to the language model request.
• Enhancement · On: Always add terms when this input uses a language model, even if the recognizer already supports hotwords.
• Replacement: Restore matched terms to their saved form after recognition, including capitalization, punctuation, or special formatting.

Check the resultCopy Anchor Link

Enable the group and test a sentence containing the term. See the Volcengine guide for online hotword tables.

Common questionsCopy Anchor Link

Why can recognition still be wrong after adding hotwords?Copy Anchor Link

Hotwords are hints, not a guarantee of correct recognition. Check the active group and your model's supported features in the compatibility list.

Why do the same weights behave differently across models?Copy Anchor Link

How weights affect recognition depends on the model. Results are not identical across providers.
