# DECTalk TTS Server
|
|
|
|
A simple Node.js server that provides DECTalk text-to-speech with MiniMax-compatible API endpoints for RedBot TTSTOY cog.
|
|
|
|
## Features
|
|
|
|
- Authentic DECTalk voice (Perfect Paul - same as Moonbase Alpha)
|
|
- MiniMax-compatible API endpoint (`/v1/t2a_v2`) for seamless integration with TTSTOY
|
|
- Simple GET endpoint (`/say?text=<text>`) for testing
|
|
- Automatic WAV to MP3 conversion using ffmpeg
|
|
- Health check endpoint (`/health`)
|
|
|
|
## Requirements
|
|
|
|
- Node.js (v14 or higher)
|
|
- npm
|
|
- ffmpeg (for audio conversion)
|
|
- Linux system (DECTalk package doesn't support macOS)
|
|
|
|
### Installing Dependencies
|
|
|
|
**Ubuntu/Debian:**
|
|
```bash
|
|
sudo apt install nodejs npm ffmpeg

|
|
sudo pacman -S nodejs npm ffmpeg
|
|
```
|
|
|
|
**macOS:**
|
|
```bash
|
|
brew install node ffmpeg
|
|
# macOS has built-in 'say' command, no need for espeak
|
|
```
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
cd dectalk-server

The `dectalk` package includes the actual DECTalk binaries and will work on Linux systems.

|
|

You can also use these in Discord:

|
[p]tts [:rate 200] speaking very fast

### Using Different Voices
|
|
|
|
**In Discord:**
|
|
```
|
|
[p]ttstoy voice Paul
|
|
[p]tts Hello, I am Perfect Paul
|
|
[p]ttstoy voice Betty
|
|
[p]tts Hello, I am Beautiful Betty
|
|
```
|
|
|
|
**Direct API:**
|
|
```bash
|
|
curl "http://127.0.0.1:33001/say?text=Hello&voice=paul" -o paul.mp3
|
|
curl "http://127.0.0.1:33001/say?text=Hello&voice=betty" -o betty.mp3
|
|
```
|
|
|
|
**List available voices:**
|
|
```bash
|
|
curl http://127.0.0.1:33001/voices
|
|
```
|
|
|
|
## Customization
|
|
|
|
The server uses the default DECTalk voice (Perfect Paul). The `dectalk` package handles all the voice synthesis internally, so no additional configuration is needed for the authentic Moonbase Alpha sound.
