Android文本到语音和语音到文本(Android Text to speech And Speech to text)

 我正在同时处理文本到语音和语音到文本。 我正在制作一个应用程序，通过文本到语音提问，并通过语音和应用程序从用户获得答案将其转换为文本。 但它不能正常工作。 两者都在同时工作，就像它说的那样，它发回信息。 我们可以给予一些延迟，以便当它停止说话时，它会听取声音并返回该文本。 `

I am working with text to speech and speech to text at the same time. I am making an app in which it ask a question through text to speech and get the answer from the user through speech and app convert it to text. but it does not work fine. both are working at the same time like what it speak, it text it back. can we give some delay so that when it stop speaking then it listen for the voice and return that text. `
