How to add a sound to Android pico TTS engine?

Question

I'm using the pico default android TTS engine with IPA caracters doing this

String text3 = "<speak xml:lang=\"fr-FR\"> <phoneme alphabet=\"ipa\" ph=\"+"+words+"\"/>.</speak>";
        myTTS.speak(text3, TextToSpeech.QUEUE_ADD, null);

It's generally working, but for some letters it doesn't like "ã" or "ɑ" etc.

So my question is, How can I add theses letters/sounds, to this TTS engine ?

Hey you can use addEarcon() to add sounds to testToSpeech link. This medthod is used to add earcons.It will link a text to a speecific sound file. You can also find example on this.

mTts = new TextToSpeech(this, new OnInitListener() {
        @Override
        public void onInit(int status) {
            mTts.addEarcon("[tock]", "com.ideal.itemid", R.raw.tock_snd);
            showRecordingView();
        }
    });

There is also a very good explanation on addEarcon in book Professional Android Sensor Programming by Greg Milette, Adam Stroud at page no 366 and 367.
