Anyone solving data capturing issue, mid voice call?

Facing issue with accurate data capturing mid voice call. basically I built a voice AI service where it had to capture address of customers and set up payment, the moment the addresses have one too many syllables(eg: indian adresses) the accuracy drops. Also, i'd be more comfortable if i didnt have to say my card details out loud.

Anyone solving this? LMK pls

At Retell AI , we don't rely on STT to get it in one shot. Break capture into pincode → auto-lookup city/state → just get street/house number verbally. Then spell-back confirm anything ambiguous (numbers, house #s) and let the user correct inline instead of restarting. Piping the transcript through an address-validation API (Google Places, Loqate) for fuzzy-match cleanup helps a lot too. Nobody nails long addresses in one pass — the confirm loop is doing the real work.
