What is Valtec Vietnamese TTS?
Valtec Vietnamese TTS is a powerful local speech synthesis tool powered by the VITS2 architecture, designed specifically for high-quality Vietnamese audio generation. Unlike cloud-based solutions, this skill operates entirely offline, ensuring data privacy and reducing latency for voice-enabled applications. It provides a robust set of Openclaw Skills for developers looking to integrate natural-sounding Vietnamese voices into their workflows without relying on external APIs.
The skill excels in providing diverse vocal options, including Northern and Southern dialects for both male and female speakers. Its standout feature is the zero-shot voice cloning, which allows users to replicate a specific voice using only a five-second reference audio clip. This makes it an essential addition to the library of Openclaw Skills for creating personalized AI interactions or localized content.
Valtec Vietnamese TTS Use Cases
- Generating natural-sounding Vietnamese voiceovers for videos or presentations without cloud costs.
- Developing offline Vietnamese virtual assistants or accessibility tools.
- Cloning specific voices for localized AI character interactions using short reference clips.
- Automating high-volume text-to-speech tasks in private, secure environments.
How Valtec Vietnamese TTS Works
- The user provides a Vietnamese text string and specifies a speaker or a reference audio file.
- The skill processes the text through a phoneme conversion layer to handle Vietnamese diacritics.
- The VITS2 model performs inference locally using either CPU or GPU (CUDA) acceleration.
- If zero-shot mode is active, the model extracts features from the reference audio to style the output.
- A high-quality WAV file is generated and saved to the specified output path.
Valtec Vietnamese TTS Setup
First, clone the repository and install the necessary Python dependencies to prepare your environment for Openclaw Skills usage:
git clone https://github.com/tronghieuit/valtec-tts.git ~/.openclaw/tools/valtec-tts
cd ~/.openclaw/tools/valtec-tts
pip install -e .
Then, update your ~/.openclaw/openclaw.json configuration to include the environment variable for this specific skill:
{
"skills": {
"entries": {
"valtec-tts": {
"env": {
"VALTEC_TTS_DIR": "~/.openclaw/tools/valtec-tts"
}
}
}
}
}
Valtec Vietnamese TTS Data Schema & Taxonomy
The skill utilizes a CLI-based schema for managing audio synthesis. On the first run, it downloads approximately 300MB of model weights to the local cache. The following parameters define how the skill organizes its output:
| Flag | Default | Description |
|---|---|---|
--speaker |
NF |
Pre-defined voice: NF (North Female), SF (South Female), NM1/2 (North Male), SM (South Male) |
--zeroshot |
N/A | Enables cloning from reference audio |
--reference |
N/A | Path to 3-10 second source WAV file |
-o, --output |
tts.wav |
Destination path for the generated audio file |
--speed |
1.0 |
Playback speed adjustment (range 0.5 to 2.0) |
