<break> tags to insert an explicit silence at a specific point:
before a verification code, between list items, or wherever punctuation alone
doesn’t give you the pause you want.
Syntax
Use the self-closing form with at most one attribute. Attribute values may
use single or double quotes. A tag with both
time and strength is not
recognized and stays in the text, and an unknown strength value becomes the
default 200 ms pause.
Durations are snapped
The model is trained on three discrete pause lengths: 200 ms, 400 ms, and 500 ms. Whatever you request is snapped to the nearest trained value (ties resolve to the longer pause), so the effective pauses are:
Need a silence longer than 500 ms? Chain tags:
<break time="500ms"/><break time="500ms"/> ≈ 1 s.
Example
- Python
- JavaScript
- cURL
Notes & limits
- Breaks survive normalization. The text around a break is normalized
independently and the pause is re-inserted afterwards, so
normalize: trueand break tags compose. - Model support:
kugel-3supports break tags (see Models). Most legacy model IDs do not: on those, break tags are stripped and synthesis continues without the pause. Usekugel-3. - Punctuation first. For natural rhythm, commas/periods/ellipses are usually better; see Punctuation as pacing. Breaks are for deliberate silences of a specific length.
- Inside
<spell>blocks, don’t place break tags. Use the spell tag’sgroupattribute for paced codes instead.
