我正在使用谷歌的对话框流程（API.AI）创建一个Android应用程序聊天机器人。问题是，如果我正在为我的意图发送文本输入，它正在给出正确的响应，而如果我使用语音输入发送相同的内容，则会得到错误的响应。我无法理解问题所在。 这是我的代码： -
public class MyChatActivity extends AppCompatActivity implements View.OnClickListener, AIListener {
public String TAG = this.getClass().getSimpleName();
private List<ChatMessageBean> chatList = new ArrayList<>();
private String CLIENT_ACCESS_TOKEN = "My dialog flow agent's client access token";
AIConfiguration config;
AIService aiService;
AIRequest aiRequest;
AIDataService aiDataService;
TextToSpeech textToSpeech;
RecyclerView chatRecyclerView,menuRecyclerView;
ChatMessageListAdapter chatMessageListAdapter;
FloatingActionButton sendMessageButton,recordMessageButton;
EditText enterMessage;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_chat_activity);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
initializeVariables();
setListeners();
}
public void initializeVariables() {
config = new AIConfiguration(CLIENT_ACCESS_TOKEN, AIConfiguration.SupportedLanguages.English, AIConfiguration.RecognitionEngine.System);
aiService = AIService.getService(getApplicationContext(), config);
aiRequest = new AIRequest();
aiDataService = new AIDataService(getApplicationContext(), config);
chatRecyclerView = (RecyclerView) findViewById(R.id.chat_list_recycler_view);
setMenuRecyclerView();
enterMessage = (EditText) findViewById(R.id.enter_text_message);
sendMessageButton = (FloatingActionButton) findViewById(R.id.send_message_button);
recordMessageButton =(FloatingActionButton) findViewById(R.id.record_message_button);
textToSpeech = new TextToSpeech(getApplicationContext(),new TextToSpeech.OnInitListener(){
@Override
public void onInit(int status) {
if(status != TextToSpeech.ERROR) {
textToSpeech.setLanguage(Locale.US);
}
}
});
}
public void setListeners() {
sendMessageButton.setOnClickListener(this);
aiService.setListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.record_message_button:
aiService.startListening();
break;
case R.id.send_message_button:
String message = enterMessage.getText().toString().trim();
enterMessage.setText("");
sendMessage(message);//sending message with text input
break;
}
}
private boolean validateMessage(String message) {
if ((message.equals("")) || (message.isEmpty()) || (message.length() == 0))
return false;
return true;
}
public void sendMessage(String message) {
// In this method i am sending the message to dialog flow
if (validateMessage(message)) {
ChatMessageBean chatMessageBean = new ChatMessageBean(message); // this is the bean I am using for chatbot app's messages
chatList.add(chatMessageBean);
chatMessageListAdapter = new ChatMessageListAdapter(chatList);// this is the adapter for recycler view that I am using for app's messages
chatRecyclerView.setAdapter(chatMessageListAdapter);
chatRecyclerView.setLayoutManager(new LinearLayoutManager(this));
aiRequest.setQuery(message);
new AsyncTask<AIRequest, Void, AIResponse>() {
@Override
protected AIResponse doInBackground(AIRequest... aiRequests) {
final AIRequest request = aiRequests[0];
try {
final AIResponse response = aiDataService.request(aiRequest);
return response;
} catch (AIServiceException e) {
}
return null;
}
@Override
protected void onPostExecute(AIResponse response) {
if (response != null) {
Result result = response.getResult();
String reply = result.getFulfillment().getSpeech();
ChatMessageBean chatMessageBean = new ChatMessageBean(reply.trim());
chatList.add(chatMessageBean);
chatMessageListAdapter = new ChatMessageListAdapter(chatList);
chatRecyclerView.setLayoutManager(new LinearLayoutManager(PersonaAssistantChatActivity.this));
chatRecyclerView.setAdapter(chatMessageListAdapter);
textToSpeech.speak(reply,TextToSpeech.QUEUE_FLUSH,null);
if(reply.trim().equalsIgnoreCase(API_ACCESS_STRING)){ //API_ACCESS_STRING is the string after which I have to get response from my own defined intents. So I am cheking if the reply is equal to API_ACCESS_STRING
String intentName=result.getMetadata().getIntentName();
switch(intentName){
case "AvailableEmployees":
Log.d(TAG, "CallIntents: AvailableEmployees:"+intentName);
String jobName=result.getStringParameter("JobName");
String date = result.getStringParameter("Date");
Log.d(TAG,"JobName:"+jobName+"date: "+date); // When I send voice input here I get jobName="AvailableEmployees" automatically, and dialog flow doesnot ask for jobName, where as with text input I get everything right.
}
}
}
}
}.execute(aiRequest);
} else {
Toast.makeText(getApplicationContext(), "Please enter some text first or record your message", Toast.LENGTH_LONG).show();
}
}
@Override
public void onResult(AIResponse result) {
String message= result.getResult().getResolvedQuery().toString().trim();
sendMessage(message);//sending message with voice input
}
@Override
public void onError(AIError error) {
Log.i(TAG, ": onError" + error);
}
@Override
public void onAudioLevel(float level) {
Log.i(TAG, ": onAudioLevel:" + level);
}
@Override
public void onListeningStarted() {
Log.i(TAG, ": onListeningStarted");
}
@Override
public void onListeningCanceled() {
Log.i(TAG, ": onListeningCanceled");
}
@Override
public void onListeningFinished() {
Log.i(TAG, ": onListeningFinished");
}
}
答案 0 :(得分：0)
您无法在sendMessage(message);//sending message with voice input方法中致电onResult。当aiService完成侦听并且已经向Dialogflow发送请求并获得响应时，将调用此方法。当您调用aiService.startListening();时，服务会检测用户说的内容并将其发送到Dialogflow。
如果你想知道文字＆＃34; aiService＆＃34;发送到Dialogflow你必须使用PartialResultsListener并实现它：
@Override
public void onPartialResults(final List<String> partialResults) {
if (!partialResults.isEmpty()) {
String partialResult = partialResults.get(0);
}
}
通过这种方式，您将获得用户所说的内容，但请注意，该方法将在onListeningFinished()结束前调用。
祝你好运Handler.postDelayed()：）
