🗣️ Speech Synthesis

The Speech Synthesis API allows websites to enumerate available text-to-speech voices, which varies by operating system and installed language packs.

🔬 Voice Enumeration

const voices = speechSynthesis.getVoices();
voices.forEach(voice => {
    console.log(voice.name);      // "Microsoft David"
    console.log(voice.lang);      // "en-US"
    console.log(voice.localService); // true/false
    console.log(voice.default);   // true/false
});

📊 What It Reveals

• Operating system: Windows, macOS, Linux have different voices
• Language packs: Installed language support
• Third-party voices: Additional TTS software
• Voice count: Number of available voices
