Voice selection

American, British, and Mandarin voices, clearly filtered.

Level 1 surfaces compatible installed American and British Android voices. Pro also presents optional Piper and Kokoro downloads, including Mandarin choices, with their RAM and power needs kept visible.

Neural voice archives come directly from open-source sherpa-onnx model releases inside Pro. Downloading a model is not cloud speech processing; speech runs locally after the archive is on the device.

Real synchronized narration in Reader.

How narration stays smooth

Passages, a natural pause, and five segments of lookahead.

Readream reads semantic passages instead of stopping at visual line edges. It can pre-generate up to five upcoming segments so the reading queue has room to stay seamless.

Pro supports background and screen-off narration through a media-style notification with play/pause plus headset button control. Basic stops narration when the reader closes, the app backgrounds, or the screen turns off.

Read deeply. Listen naturally. Create freely.
