Embarcadero has a blog post from September 2013 that highlights a Text To Speech (TTS) unit that was created by Jeff Overcash. The TTS unit wraps the native Android Text to Speech API and gives you access to it from your Delphi XE5 Firemonkey application. You can take a look at the Android SDK information for android.speech.tts to see the full help on using the API. The interfaces that are implemented in the wrapper are listed below:
|
1 2 3 4 5 6 7 8 9 |
JSynthesisCallback = interface; // android.speech.tts.SynthesisCallback JSynthesisRequest = interface; // android.speech.tts.SynthesisRequest JTextToSpeech = interface; // android.speech.tts.TextToSpeech JTextToSpeech_Engine = interface; // android.speech.tts.TextToSpeech$Engine JTextToSpeech_EngineInfo = interface; //android.speech.tts.TextToSpeech$EngineInfo JTextToSpeech_OnInitListener = interface; // android.speech.tts.TextToSpeech$OnInitListener JTextToSpeech_OnUtteranceCompletedListener = interface; // android.speech.tts.TextToSpeech$OnUtteranceCompletedListener JTextToSpeechService = interface; // android.speech.tts.TextToSpeechService JUtteranceProgressListener = interface; // android.speech.tts.UtteranceProgressListener |
And here is a sample from the demo that is included with the wrapper:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |
procedure TForm1.TttsOnInitListener.onInit(status: Integer); var Result : Integer; begin if (status = TJTextToSpeech.JavaClass.SUCCESS) then begin result := FParent.tts.setLanguage(TJLocale.JavaClass.US); if (result = TJTextToSpeech.JavaClass.LANG_MISSING_DATA) or (result = TJTextToSpeech.JavaClass.LANG_NOT_SUPPORTED) then ShowMessage('This Language is not supported') else begin FParent.Button1.Enabled := true; FParent.button2.Enabled := false; end; end else ShowMessage('Initilization Failed!'); end; procedure TForm1.SpeakOut; var text : JString; begin text := StringToJString(Memo1.Lines.Text); tts.speak(text, TJTextToSpeech.JavaClass.QUEUE_FLUSH, nil); end; |

How I can configure it in Spanish?
What I did was, I download a spanish tts to my android phone, then on “TttsOnInitListener.onInit” procedure I replace this:
result := FParent.tts.setLanguage(TJLocale.JavaClass.US);
with this
result := FParent.tts.setLanguage(TJLocale.JavaClass.getDefault);
Hi, how download the spanish language to android? and to change this line:
FParent. tts.setLanguage (TJLocale.JavaClass.getDefault); the app crash.
Speech to Text without VirtualKeyboard button?
Not sure what you mean?
It does not work on the Galaxy . (TTS INIT ERROR)
What is the reason ?
my phone: Samsung GalaxyNote-2 (Jellybin 4.3)
First of all, thank you for this example.
On my Samsung S3 (Android 4.3) example doesn’t work.
Program crashes on
tts := TJTextToSpeech.JavaClass.init(SharedActivityContext, ttsListener);
Prior to upgrade of Android version everything was working fine. On another device (Android 4.0.4) there is no problem.
I noticed that there were some changes in API level 18 for TTS. Maybe that’s the reason?
Best regards,
