[Android] TTS(Text To Speech) 사용하기

Text To Speech는 안드로이드에서 제공하는 텍스트 음성변환 기능이다.

아래 영상과 같이 텍스트 입력 부분에 글을 입력하고

말하기 버튼을 누르면 음성으로 출력해준다!

    xmlns:tools="http://schemas.android.com/tools"
    package="com.example.ttspractice">

    <queries>
        <intent>
            <action android:name="android.intent.action.TTS_SERVICE" />
        </intent>
    </queries>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        
    </application>

</manifest>

 

Android 11을 타겟팅 하는 경우 AndroidManifest에서 INTENT_ACTION_TTS_SERVICE을 반드시 선언해야 한다.(Line 6~10)

그렇지 않으면 소리가 나지 않는다.
