American and British English voices, clearly filtered.

Level 1 shows compatible American and British Android voices already on your phone. Pro also shows optional Piper and Kokoro downloads with clear memory and power needs.

How Readream keeps speech smooth

Natural pauses and up to five parts prepared ahead.

Readream reads full passages instead of stopping at each screen line. It can prepare up to five parts ahead to reduce gaps between passages.

Pro can keep reading aloud in the background or when the screen is off. You can use play or pause from a media notification and headset buttons. Basic stops when you close the reader, move the app to the background, or turn the screen off.

Read deeply. Listen naturally. Create freely.
