如何从安卓识别器意图获取实时数据?

Question

1. 我想调用RecognizerIntent并让它永远循环，直到用户决定关闭它，我将如何做到这一点？ 每当声音在识别输入后停止时，当前的 Android 识别器意向就会关闭。例如：如果识别出"hi"，则如果用户在此之后大约一两秒钟内不说任何话，则活动将关闭。有什么方法可以阻止活动关闭吗？并永远持续到我选择关闭它(也许通过第二次单击按钮？

2. 我还想获取有关所说的内容的实时数据，而不是在关闭后将其作为活动的额外数据传递。

   package com.example.myapplication
   import android.app.Activity
   import android.content.Intent
   import androidx.appcompat.app.AppCompatActivity
   import android.os.Bundle
   import android.speech.RecognizerIntent
   import android.widget.Toast
   import kotlinx.android.synthetic.main.activity_recordinit.*
   import java.lang.Exception
   import java.util.*
   class Recordinit : AppCompatActivity() {
   val   REQUESTCODE3 = 4
   
   fun audioaction(){
   val speechtotextintent = Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH)
   speechtotextintent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.EXTRA_LANGUAGE_MODEL)
   speechtotextintent.putExtra(RecognizerIntent.EXTRA_LANGUAGE , Locale.getDefault())
   speechtotextintent.putExtra(RecognizerIntent.EXTRA_PROMPT , "Click To Begin Listening on the threat!!")
   try {
   //check to see if the activity can work on this device... and it meets the requirements
   startActivityForResult(speechtotextintent , REQUESTCODE3 )
   
   }
   //if there is any errors we will let the user know in a popup message.
   catch (e : Exception){
   Toast.makeText(this , e.message , Toast.LENGTH_SHORT  ).show()
   }
   
   }
   override fun onCreate(savedInstanceState: Bundle?) {
   super.onCreate(savedInstanceState)
   setContentView(R.layout.activity_recordinit)
   microphonebutton.setOnClickListener{
   audioaction()
   }
   
   }
   override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
   if (REQUESTCODE3 == requestCode ){
   when (resultCode == Activity.RESULT_OK ){
   
   }
   }
   super.onActivityResult(requestCode, resultCode, data)
   }
   

   }

编辑：我发现EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS允许我决定活动如何对沉默做出反应。但我仍然想找到一种方法来实时监控所说的内容。

也许这可以帮助您在活动调用时说出单词。

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == REQUEST_CODE10) {
if (resultCode == RESULT_OK && data != null) {
var result : ArrayList<String> = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS)
}
}
}
