Natural on-device voice (Piper)

's own natural on-device voices; free for everyone and offline. They are listed grouped by language, in six languages: Turkish (Fettah, DFKI), English (Lessac and Kristin US, Alba UK), German (Thorsten), Spanish (Davefx, Sharvard), French (Siwis), Portuguese (Faber, Brazil). Each voice is downloaded once (about 64 MB; the size shows on the row) and then works without internet.

1. 1Tap the download icon next to a voice; on mobile data you are asked first, and progress shows on the row.
2. 2Play a sample with the speaker icon next to a downloaded voice, or delete it with the bin.
3. 3Tap a row to choose the voice; if reading is under way it continues from the current sentence with the new voice.

Each natural voice reads in its own language. Parts of a document in another language, and translations, are read with a downloaded natural voice for that language if there is one, otherwise with the device voice; for example, while Fettah reads a Turkish document, an English quote is read by Lessac. Even if the selected voice isn't downloaded, reading doesn't stop if another natural voice is.
