text: 'Hello, how are you?',
options: {
voice: 'en-US-Standard-A',
rate: '+10%',
volume: '+0%',
pitch: '+0Hz'
}
});
Text-to-Speech with File 生成语音文件
await skill.execute({
action: 'tts',
text: 'Hello, how are you today?',
options: {
voice: 'zh-CN-XiaoxiaoNeural'
}
});
// Returns: { success: true, media: 'MEDIA: /path/to/file.mp3' }
Direct Speak 直接播放
await skill.execute({
action: 'speak',
text: 'Hello!'
});

Security 安全
This skill implements enterprise-grade security best practices:
🛡️ Security Features
| Feature | Implementation |
|---|---|
| Input Validation | Voice parameter whitelist validation - only allowed voices can be used |
| No Shell Execution | Uses spawn() with array arguments instead of shell command concatenation |
| Command Injection Prevention | All user inputs are properly validated and escaped |
| Path Safety | Fixed script path prevents path traversal |
Security Details
// ❌ UNSAFE - Don't use exec with string concatenation
exec(`py script.py "${userText}" --voice ${userVoice}`);
// ✅ SAFE - Use spawn with array arguments
spawn('py', [scriptPath, text, '--voice', voice], { shell: false });
Voice Whitelist
Only these voices are allowed:
const allowedVoices = [
'zh-CN-XiaoxiaoNeural', 'zh-CN-YunxiNeural', 'zh-CN-YunyangNeural',
'zh-CN-YunyouNeural', 'zh-CN-XiaomoNeural',
'en-US-Standard-C', 'en-US-Standard-D', 'en-US-Wavenet-F',
'en-GB-Standard-A', 'en-GB-Wavenet-A',
'ja-JP-NanamiNeural', 'ko-KR-SunHiNeural'
];
Any invalid voice parameter will be rejected and replaced with the default voice.
