# Breeze Text to Speech - ComfyUI Built-in Node Documentation

> Converts text into speech with Breeze TTS 2.

Converts text into speech with Breeze TTS 2. Pick a Breeze voice, choose the language of the text, and optionally direct how the line is performed. English and Chinese can use either Breeze TTS 2 model; every other language uses Breeze TTS 2 Multilingual.

## Inputs

### Common Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `voice` | Breeze voice to speak with, from Breeze Voice Selector or one of the Breeze voice creation nodes. | BREEZE\_VOICE | Yes | - |
| `text` | Text to speak, 1 to 1000 characters. Audio tags such as `(laughs)` or `(sighs)` are performed instead of read. Default: empty. | STRING | Yes | 1 to 1000 characters |
| `language` | Language of the text. English and Chinese can use either model; other languages use Breeze TTS 2 Multilingual. A voice sounds best in its own language, so for another language use a copy made with Breeze Voice Localize. | DYNAMIC\_COMBO | Yes | Multiple options available |
| `delivery` | How the line is performed: `neutral` keeps the voice as it is, `directed` follows written instructions. Default: `"neutral"`. | DYNAMIC\_COMBO | Yes | `"neutral"` `"directed"` |
| `speed` | Tempo multiplier that leaves the pitch unchanged. Default: 1.0. | FLOAT | No | 0.5 to 2.0 (step 0.05) |
| `seed` | Controls whether the node re-runs; results are non-deterministic regardless of the seed. Default: 42. | INT | No | 0 to 2147483647 |
