Text to Speech not working in Android 4.2 Jelly Bean
<p>We added voice prompts to our app using the Text to Speech API a couple years ago and it has been working well. Recently, we started receiving email from users that upgraded to Android 4.2 Jelly Bean saying that voice prompts are not working and that they are getting a message that the voice data is missing and they need to download it. When they click to download they are given the option of downloading languages other than English.</p>

<p>We implemented text to speech following this <a href="http://android-developers.blogspot.fr/2009/09/introduction-to-text-to-speech-in.html" rel="nofollow">post</a> on the Android Developer's Blog. We are invoking the <code>TextToSpeech.Engine.ACTION_CHECK_TTS_DATA</code> intent and if anything other than <code>TextToSpeech.Engine.CHECK_VOICE_DATA_PASS</code> is returned we invoke the <code>TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA</code> intent.</p>

<p>We don't have access to a device running 4.2. I went into a local store today and downloaded the app on a Nexus 7 tablet with 4.2 installed and was able to reproduce the problem. However, when we create an AVD based on the Nexus 7 and run the emulator the voice prompts work fine and we are not able to reproduce the issue.</p>
