This app can shape delivery with browser speech synthesis, but it cannot clone your voice locally by itself. To get closer to your own sound, pick the nearest English system voice and tune speed, pitch, warmth, brightness, and cadence until the readback sits where you want it.

Buttons are wired with direct handlers, speech cancellation before new playback, state guards for pause and resume, and voice refresh checks so the app stays responsive during repeated use.

• Auto-refreshes voice list when the browser exposes voices later.
• Stops current speech before starting a new request.
• Exports and imports full tuning profiles as JSON.
• Updates counters and fit meters as you type and adjust.
