Text To Speech

Today, I set the "TTS" function in my app!!

First, accessing the "TextToSpeech" function provided in android

Declaring TextToSpeech: control the "TTS" android library

Declaring TTSUtteranceProgressListener: listener class that receive the station of speech (start, error, end)

Second, create TextToSpeech instance in "onCreate" process

Initializing preferences -> set to Korean speech

Third, speechOut method to print out text to speech

AudioManager: get volume information from audio preferences

maxVolume: get possible max volume to print out

curVolume: get current volume

am.setStreamVolume: set volume for the maximum volume

Fourth, if-else statement produced by the version of android SDK

One way implements when android SDK version is over 11

Other way implements when android SDK version is under 11

After speakApi13 implements, the volume will be reset as a current volume

Fifth, the method of printing out text to speech

Final result: Let's see how it works!!
