Android文本语音转换和语音文本转换

Question

我正在同时处理文本到语音和语音到文本。 我正在开发一个应用程序，其中它通过文本到语音来询问问题，并通过语音从用户那里得到答案，并且应用程序将其转换为文本。 但它不能正常工作。 两者都像说话一样在同时工作，然后发回短信。 我们可以给它一些延迟吗，以便当它停止说话时，它会听到声音并返回该文本。 `

Answer 1

尝试更改：

speakOut();
promptSpeechInput();

至

promptSpeechInput();

然后添加：

speakOut();

后

eText1.setText(result.get(0));

完成获取文字后，应该说出文字

编辑：使用它来确定语音何时结束。 只是在调用提示符时的提示SpeechInput（）
