Android Text To Speech -- Check if any app is using TTS service -

is there way determine whether "any" app using android text-to-speech engine? meaning, they've created instance of text-to-speech (http://developer.android.com/reference/android/speech/tts/texttospeech.html) , ready utilize it?

i trying work around bug in several apps assume when "any" accessibility manager service enabled, "talkback" service. result of bug, when enable "my" accessibility service, buggy apps startup tts , start talking.

as fix, when accessibility service enabled, check see if has enabled tts, , if so, disable service not annoy user. inform user service disabled because running on buggy platform.

thanks, j
