Tag Usage Guide

Pause tags

You can use pause tags anywhere in the text. Various formats are supported:

  • Seconds: [pause:1.5], [pause:2s], [pause:3]
  • Milliseconds: [pause:500ms], [pause:1200ms], [pause:800ms]
Welcome to our show! [pause:1s] Today we will discuss interesting topics.
[Alice] I am so excited! [pause:500ms] This will be great.
[pause:2] Let's move on to the main part.

Paralinguistic tags

The service supports tags for non-verbal sounds: breathing, laughter, coughing, sighs, gasps, background noise, lip smacks, and emphasis. These tags are processed directly by the model during speech generation.

TagEffectExample
<breath>BreathI'm tired <breath> let's rest
<quick_breath>Quick breathRunning <quick_breath> almost there
<laughter>LaughterThat's hilarious <laughter>!
<cough>CoughExcuse me <cough> sorry
<sigh>SighFine <sigh> I'll do it
<gasp>Fright or surpriseOh no <gasp> what happened?
<noise>Background noiseWalking <noise> through the forest
<lipsmack>Lip smackTasty <lipsmack> food
<accent>Accent or emphasisVery <accent> important

Wrapper tags are also supported:

TagEffectExample
<laughing>text</laughing>Speak text with laughter<laughing>so funny</laughing>!
<strong>text</strong>Emphasize text<strong>very important</strong>

Language and character switching

Use square bracket syntax for language and speaker changes:

[en:Alice] Hello world
[ru:Bob] Привет мир
[zh:] 你好世界

Recommendations

  1. Use angle brackets such as <breath> to avoid conflicts with character names.
  2. Insert tags where they fit natural speech, such as pauses before an answer or sighs when tired.
  3. Use tags in moderation: 1-2 tags per sentence is usually enough.
  4. The model controls effect strength; parameters cannot change laughter volume or sigh duration.
