# ComfyUI-SparkTTS
ComfyUI_SparkTTS
This is a ComfyUI custom node implementation of [SparkTTS](https://github.com/SparkAudio/Spark-TTS), an advanced text-to-speech system that uses the power of large language models (LLM) for highly accurate and natural-sounding voice synthesis.
![SparkTTS_Node_Sample](https://github.com/user-attachments/assets/ca18bec4-d4b4-44d8-9a0e-a969a279da13)
## Features
ComfyUI-SparkTTS provides the following main functionalities:
1. **Voice Creation**: Create a customized voice by adjusting parameters like gender, pitch, and speed.
2. **Voice Cloning**: Clone a voice from a reference audio sample.
3. **Advanced Voice Cloning**: Clone a voice from a reference audio with control over pitch and speed.
4. **Audio Processing**: Load and process audio files.
5. **Speech-to-Text**: Convert speech to text using Whisper.
6. **Audio Recording**: Directly record audio for voice cloning or processing.
## Installation
### Method 1. install on ComfyUI-Manager, search `Comfyui-SparkTTS` and install
install requirment.txt in the ComfyUI-SparkTTS folder
```bash
./ComfyUI/python_embeded/python -m pip install -r requirements.txt
```
### Method 2. Clone this repository to your ComfyUI custom_nodes folder:
```bash
cd ComfyUI/custom_nodes
git clone https://github.com/1038lab/ComfyUI-SparkTTS
```
install requirment.txt in the ComfyUI-SparkTTS folder
```bash
./ComfyUI/python_embeded/python -m pip install -r requirements.txt
```
### Method 3: Install via Comfy CLI
Ensure `pip install comfy-cli` is installed.
Installing ComfyUI `comfy install` (if you don't have ComfyUI Installed)
install the ComfyUI-SparkTTS, use the following command:
```bash
comfy node install ComfyUI-SparkTTS
```
install requirment.txt in the ComfyUI-SparkTTS folder
```bash
./ComfyUI/python_embeded/python -m pip install -r requirements.txt
```
### 4. Manually download the models:
- The model will be automatically downloaded to `ComfyUI/models/TTS/SparkTTS/` when first time using the custom node.
- Manually download the SparkTTS-2.0 model by visiting this [link](https://huggingface.co/SparkAudio/Spark-TTS-0.5B/tree/main), then download the files and place them in the `/ComfyUI/models/TTSSparkTTS/SparkTTS-2.0` folder.
## Nodes
### SparkTTS Voice Creator 🔊
This node allows you to create a customized voice by adjusting parameters.
**Inputs:**
- `text`: Text to synthesize.
- `gender`: Gender of the voice (female or male).
- `pitch`: Pitch level of the voice (very_low, low, moderate, high, very_high).
- `speed`: Speed level of the voice (very_low, low, moderate, high, very_high).
- `batch_texts` (optional): Additional texts for better control over pacing and intonation.
**Outputs:**
- `audio`: Generated audio with the customized voice.
### SparkTTS Voice Clone 🔊
This node allows you to clone a voice from a reference audio sample.
**Inputs:**
- `text`: Text to synthesize with the cloned voice.
- `reference_audio`: The audio sample to clone the voice from.
- `reference_text`: Transcript of the reference audio to improve cloning quality.
- `max_tokens`: Controls the maximum length of generated speech.
- `batch_texts` (optional): Additional texts for better control over pacing and intonation.
**Outputs:**
- `audio`: Generated audio with the cloned voice.
### SparkTTS Advanced Voice Clone 🔊
This node allows you to clone a voice from a reference audio with control over pitch and speed.
**Inputs:**
- `text`: Text to synthesize with the cloned voice.
- `reference_audio`: The audio sample to clone the voice from.
- `reference_text`: Transcript of the reference audio to improve cloning quality.
- `pitch`: Pitch level of the voice.
- `speed`: Speed level of the voice.
- `max_tokens`: Controls the maximum length of generated speech.
- `batch_texts` (optional): Additional texts for better control over pacing and intonation.
**Outputs:**
- `audio`: Generated audio with the cloned voice.
### Audio Recorder 🔊
This node allows you to directly record audio.
**Inputs:**
- `recording`: Set to True to start recording audio.
- `recording_duration`: Recording duration in seconds.
- `sample_rate`: Audio sample rate.
- `noise_threshold`: Noise reduction threshold.
- `smoothing_kernel_size`: Size of the kernel used for smoothing the audio signal.
**Outputs:**
- `audio`: Recorded audio data.
