English Text-to-Speech & Read Aloud Tool

In the top settings bar:

• Change Voice Role: Open the "Voice Role" dropdown to select from American English (en-US), British English (en-GB), and other male or female voices.
• Adjust Speed: Fine-tune the "Speed" option (from 0.5x slow to 2.0x fast). A rate of 0.8x - 0.9x is recommended for shadowing practice.

Two convenient methods are available for repeating a sentence:

• Popover Menu: Click any word in the target sentence, and select "🎯 Read Sentence Only" or "🔁 Loop This Sentence" from the popup menu.
• Global Loop: Check the "Loop playback" option under the text input box to restart reading automatically when finished.

Click any word in the text display panel, then select "🔊 Read Word" from the popup menu to instantly listen to its individual pronunciation. Click blank space to close the menu.

Check the "☑ Auto-scroll" box in the display panel header (enabled and saved by default):

• Viewport Tracking: As speech progresses through long text, the page smoothly scrolls to keep the currently active sentence centered on screen.
• Manual Control: Uncheck "Auto-scroll" anytime to pause tracking and browse the article freely.

This tool supports high-precision sentence active glowing and real-time word focus highlighting:

• Engine Capability Differences: Speech engines across operating systems and browsers vary. Some voices support exact word-level alignment, while others support sentence-level highlighting.
• Optimization Tip: Try testing different "Language" and "Voice Role" options in the top settings bar to find your preferred voice with full word-level highlighting support.
