Text To Speech 안드로이드 TTS

텍스트를 음성으로 합성해 주는 TTS(Text To Speech)기능을 사용해 보자.

 

레이아웃에 에디트텍스트와 버튼을 적당히 배치한다.

                // QUEUE_FLUSH - Queue mode where all entries in the playback queue (media to be played
                // and text to be synthesized) are dropped and replaced by the new entry.

    }
}

 

소스를 입력하고 빌드한다.

 

텍스트를 입력하고 버튼을 터치하면 음성이 출력된다.
