Voice
Natural calloutsCustom words only
Record each phrase with your microphone (permission required). The same phrase uses its recording across word lists. No network, account, or usage fee; this does not generate speech for new words. Unrecorded words use the selected built-in voice. Enhanced/Premium voices may not appear in iPhone Safari. Recordings stay on this device and may be erased with Safari site data. Keep this screen visible during drills.
