Как транскрибировать большой аудиофайл в приложении iOS? ⇐ IOS

[Anonymous]

Я успешно использовал sfspeechRecognizer для транскрибирования небольших аудиофайлов. Но я хочу транскрибировать речь в текст из 30-минутного аудио-файла. Я придумал это решение, но оно не работает вообще. p> [Утилита] +[Afaggregator logdictationFailedWiterRor:] error domain = kafassistanterrordomain code = 203 "corpt" userinfo = {nslocalizedDescription = corpt, nsunderlyingError = 0x28315ca80 {ошибка domain = sirispeecherrord код = 102 "(null)"/pully "/null)"/Pullord pully "/null" (null) "/pull etull)
