Я интегрирую диалоговый поток в мой файл swift, который включает вопросы, отображаемые в одном поле с именем chipresponse, и он должен выводить голос, а затем поле сообщения получит ввод через голос, и вот мой код, и он завершается.

Когда я использую этот код, голосовой текст чип-ответа становится слишком низким, а затем завершается и произносит nullptr () - иногда нажмите на ошибку, а иногда она показывает ошибку кода IFFormat
Пожалуйста, помогите мне,Спасибо
