iOS 음성을 텍스트 API에, 텍스트를 음성 API에 함께 사용하려고합니다. 기본적으로 사용자는 말을하고 텍스트는 텍스트로 기록됩니다. 그런 다음 사용자는 텍스트보기의 텍스트에서 음성으로 텍스트를 제공하는 버튼을 누릅니다. 내 오류는 사용자가 speech-to-text 단추를 누르면 text to speech 단추가 작동을 멈추는 것입니다. 그러나 텍스트 단추로 연설을 전혀 누르지 않고 키보드를 통해 텍스트보기에 일부 텍스트를 입력하지 않으면 텍스트가 음성 단추로 작동합니다. 텍스트 버튼을 연설하는 데 문제가 있다고 생각합니다. 내 코드에서 어떤 오류도 발생하지 않고 있으며 무슨 일이 일어나고 있는지 혼란 스럽다. 누를 때텍스트 음성 변환 오류, 텍스트 음성 변환 버튼과 충돌
