Я хочу к разработке приложения, которое должно поддерживать речи в текст и текста в речь,текста в речь и речи в текст Признание -> Самосовершенствование - Распознавание происходит
я) Речь на Шрифтом- процедуры, у меня есть используется речевая структура для речи в тексте, всякий раз, когда я открываю приложение, и если я начинаю говорить, приложение должно распознавать голос и должно преобразовывать речь в текст. Это работает
ii) Текст в речь - процедура -i есть используется библиотека AVFoundation и MediaPlayer. Если пользователь нажимает кнопку воспроизведения, он должен преобразовать текст, т. е. все, что появляется на экране, в речь. Работая сейчас.
Вот проблема я перед при обработке текста в речь, то распознаватель речи распознает голос игры и печать слова снова в текстовом поле.
Пример: если я говорю «Hello Good Morning», это печатает в текстовом поле, а затем, если я нажимаю кнопку воспроизведения, он воспроизводит голос Привет, Доброе утро, но в это время речь в тексте распознает этот голос i значит само- признание и это печать "Hello Good Morning Hello Good Morning"
Я хочу, чтобы остановить Speech To Text процесса при обработке Text To Speech
для этого я остановился запрос распознавания речи во время воспроизведения речи здесь код,
