Listening to written passages read aloud assists proofreading, editorial revision, language pronunciation practice, and visual accessibility. This audio reader harnesses the Web Speech API built into modern web browsers to convert written text into spoken audio using your device's native speech synthesizers.

### Speech Synthesis Controls The reader provides granular control over audio playback parameters: - **Operating System Voice Selection:** Automatically queries installed system voices from your operating system (such as Microsoft David/Zira on Windows, Apple Samantha on macOS/iOS, or Google voices on Android/Chrome). - **Playback Speed (Rate):** Adjusts speech velocity between half speed (0.5×) and double speed (2.0×), with 1.0× providing natural conversational pacing. - **Voice Pitch:** Tunes voice frequency between deep resonance (0.5) and higher pitch (1.5), with 1.0 representing standard vocal timbre. - **Interactive Playback Controls:** Offers dedicated buttons to Speak, Pause, Resume, and Stop playback without restarting the passage from the beginning.

### Worked Speech Example Consider reviewing an editorial draft: 1. Paste your draft paragraph into the text box. 2. Select your preferred voice from the Voice dropdown menu (e.g., a natural English voice). 3. Set Rate to 1.1× for efficient proofreading and Pitch to 1.0. 4. Click **Speak**. Your browser's audio synthesizer immediately speaks the text through your headphones or speakers. 5. If you notice an awkward phrase, click **Pause**, edit the sentence, and click **Resume**.

### On-Device Audio Privacy Speech synthesis executes entirely on your physical device using the browser's built-in `window.speechSynthesis` API. Your text is never transmitted to remote cloud transcription APIs or speech servers.
