If the sounds come out wrong, switch Play to “Words only”. Speech engines mangle isolated phonemes — they were never trained on them — but they say real words accurately, so Words only plays two real words sharing the sound and your daughter works out the phonogram. It’s the mode that always sounds right. For the voice itself, pick one marked ★; on Windows, opening this page in Microsoft Edge unlocks Microsoft’s “Natural” neural voices. Hand signs are ASL fingerspelling, one shape per letter.
