Obtaining Free-form Speech Input

In addition to using voice actions to launch activities, you can also call the system's built-in Speech Recognizer activity to obtain speech input from users. This is useful to obtain input from users and then process it, such as doing a search or sending it as a message.

In your app, you call

startActivityForResult()

using the

ACTION_RECOGNIZE_SPEECH

action. This starts the speech recognition activity, and you can then handle the result in

onActivityResult()

.

private static final int SPEECH_REQUEST_CODE = 0; // Create an intent that can start the Speech Recognizer activity private void displaySpeechRecognizer() {    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); // Start the activity, the intent will be populated with the speech text    startActivityForResult(intent, SPEECH_REQUEST_CODE); } // This callback is invoked when the Speech Recognizer returns. // This is where you process the intent and extract the speech text from the intent. @Override protected void onActivityResult(int requestCode, int resultCode,        Intent data) {    if (requestCode == SPEECH_REQUEST_CODE && resultCode == RESULT_OK) {        List<String> results = data.getStringArrayListExtra(                RecognizerIntent.EXTRA_RESULTS);        String spokenText = results.get(0);        // Do something with spokenText    }    super.onActivityResult(requestCode, resultCode, data);

String language =  "us-US"; Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,language); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, language); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, language); intent.putExtra(RecognizerIntent.EXTRA_ONLY_RETURN_LANGUAGE_PREFERENCE, language); startActivityForResult(intent, RESULT_SPEECH_GUEST);

Android wear 개발방법(Adding Voice Capabilities)

두종류의 voice action types

System-provided  이미 시스템상에서 지정된 voice action

App-provided  app에서 지정하거나 특정 app의 activity를 실행하는 경우

Declare System-provided Voice Actions

When users speak the voice action, your app can filter for the intent that is fired to start an activity. If you want to start a service to do something in the background, show an activity as a visual cue and start the service in the activity. Make sure to call finish() when you want to get rid of the visual cue.

<activity android:name="MyNoteActivity">      <intent-filter>          <action android:name="android.intent.action.SEND" />          <category android:name="com.google.android.voicesearch.SELF_NOTE" />      </intent-filter>  </activity>

몇몇의 voice intent의 예시들

더 많은 voice intent를 참조하려명  see Common intents.

Declare App-provided Voice Actions

you can start your apps directly with a "Start MyActivityName" voice action.

<application>  <activity android:name="StartRunActivity" android:label="MyRunningApp">      <intent-filter>          <action android:name="android.intent.action.MAIN" />          <category android:name="android.intent.category.LAUNCHER" />      </intent-filter>  </activity> </application>

label에 해당하는 내용이 Start 다음에 들어갈 명령어에 해당한다.

Obtaining Free-form Speech Input(사용자로 부터 음성으로 입력값을 받는 방법)

private static final int SPEECH_REQUEST_CODE = 0; // Create an intent that can start the Speech Recognizer activity private void displaySpeechRecognizer() {    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); // Start the activity, the intent will be populated with the speech text    startActivityForResult(intent, SPEECH_REQUEST_CODE); } // This callback is invoked when the Speech Recognizer returns. // This is where you process the intent and extract the speech text from the intent. @Override protected void onActivityResult(int requestCode, int resultCode,        Intent data) {    if (requestCode == SPEECH_REQUEST_CODE && resultCode == RESULT_OK) {        List<String> results = data.getStringArrayListExtra(                RecognizerIntent.EXTRA_RESULTS);        String spokenText = results.get(0);        // Do something with spokenText    }    super.onActivityResult(requestCode, resultCode, data); }

startActivityForResult() 를 통해 음성으로 입력값을 받을 activity를 실행한다.이때 action은  ACTION_RECOGNIZE_SPEECH 으로 지정한다. 그리고 그 결과는  onActivityResult() 에서 받을수 있다.
