Readable follows your Mac’s language. To change it, open System Settings → General → Language & Region; you can also set a language for Readable alone under Applications on that page.
The language Readable speaks depends on the voice you choose — see Choosing a Voice. Word prediction follows your Mac’s language and spelling preferences.
