voicevox

ROS Interface for VOICEVOX (AI speech synthesis)

Quick Start

Choose the deployment pattern that best fits your needs:

# Pattern A: Direct Docker + ROS client (Multi-machine) | 直接Docker + ROSクライアント（マルチマシン）
# Server machine:
docker run --rm --gpus all -p '50021:50021' voicevox/voicevox_engine:nvidia-ubuntu20.04-latest
# Client machine:
roslaunch voicevox voicevox_texttospeech.launch host:=<server_ip> port:=50021

# Pattern B: ROS-managed Docker + ROS client (Multi-machine) | ROS管理Docker + ROSクライアント（マルチマシン）
# Server machine:
roslaunch voicevox voicevox_texttospeech.launch docker_only:=true
# Client machine:
roslaunch voicevox voicevox_texttospeech.launch host:=<server_ip> port:=50021

# Pattern C: All-in-one (Docker + ROS on same machine) | オールインワン（同一マシンでDocker+ROS）
roslaunch voicevox voicevox_texttospeech.launch use_docker:=true

# Pattern D: Local VOICEVOX without Docker (CPU only) | ローカルVOICEVOX（Dockerなし、CPU版）
# VOICEVOX engine is automatically installed during catkin build
roslaunch voicevox voicevox_texttospeech.launch

Patterns A-C provide GPU acceleration support through Docker. Pattern D runs locally with CPU only. パターンA-CはDockerを通じたGPUによる高速な音声合成をサポート。パターンDはCPUのみでローカル実行。

TERM

VOICEVOX is basically free to use, but please check the terms of use below.

TERM

Each voice synthesis character has its own rules. Please use this package according to those terms.

Installation

Build this package.

cd /path/to/catkin_workspace
catkin build voicevox

Optional (Using Docker with GPU acceleration)

VOICEVOX supports Docker deployment with GPU acceleration, which enables significantly faster speech synthesis compared to CPU-only processing.

Prerequisites

First, install the NVIDIA Container Toolkit:

https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html

Setup

Pull the GPU-enabled VOICEVOX Docker image:

```bash
