* Improved native TTS interface header.David 'Digit' Turner2010-06-112-74/+129
| | | | | | | | | | | | | | | The purpose of this patch is to add a C-based ABI that can be exposed by the NDK for developers wanting to write a TTS Engine. This replaces the C++ ABI that is currently under frameworks/base/include/tts/TtsEngine.h but is *binary* compatible with it. As a consequence, the svox pico plugin under external/svox/pico/tts/, which links against tts/TtsEngine.h can be loaded by the TTS service properly. Another patch would modify the pico tts to use <android/tts.h>, then we will be able to get rid of <tts/TtsEngine.h> in the source tree. Change-Id: I16844cef9b5b006cc32655a29e4f9f193c8c1a91

The track volume should be initialized to it nominal level. Volumes above 1 do not provide amplification, so setting the volume to 2 is not necessary.

| | | | | | | If files were being synthesized to while the service was being killed, it would have left partially written files (with no header). This CL checks if the service is rendering to a file at the time the service is destroyed: if it is, it will stop the rendering and deletes the file.

| * Fix bug 2046705 where the output of the speech synthesizer is too low.Jean-Michel Trivi2009-08-141-3/+93
| | | | | | | | | | | | | | | | | | | | The language files for the SVOX Pico engine result in the output of the synthesizer to be too soft, and barely audible on a phone speaker. The change implements a low shelf filter on the output of the synthesis and a drastic amplification. This works as intended because the synthesized data contains too much energy in the lower frequencies that is wasted on a phone speaker. Once filtered out, they leave room for amplication to address the volume issue.

| * Fix bug 2043140.Jean-Michel Trivi2009-08-111-18/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | A race condition is encountered when an application invokes shutdown() on its TextToSpeech object while is has speak() requests still running. Since the TTS service destructor releases the synthesizer resources and sets the corresponding synth reference to null, an NPE was observed. The fix consists in catching NPEs whenever the sNativeSynth object is accessed, and return the matching error for the call. This change is a "low risk" version of the fix for bug 2025765i (same issue) which was reverted because it was higher risk than this CL: it affected the logic of each call to sNativeSynth. This CL only sets an error code when an NPE is fired because sNativeSynth is null.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Talkback produced a null pointer exception when being enabled and disabled repeatedly due to a race condition between the onDestroy() of the service, and the use of the service itself. The error occurs when one Talkback thread initiates the destruction of the service (call to onDestroy()) when it invokes shutdown() on its TextToSpeech instance (the client of the service). At the same time, Talkback tries to say that "Accessibility" is unchecked from another thread. During onDestroy(), the reference to the TTS engine (sNativeSynth) is reset to null, which is used in the service in speakInternalOnly(), and setLanguage(). The fix consists in the addition of a static variable that signals that the service has entered onDestroy(). Once this flag is set, all method invocations on sNativeSynth will be dismissed. Note that access to the native resources used by sNativeSynth are synchronized at the native layer, therefore preventing sNativeSynth.shutdown() to interfere with a sNativeSynth.speak() call already underway.

| | | | | | | | | | | | | | | | | | Removed the TTS_ prefix in the TextToSpeech class to follow the standard naming convention. Moved the TTS-related intents from the Intent class to TextToSpeech and TextToSpeech.Engine. Renamed the TextToSpeech.Engine constants that are used as extras for the ACTION_TTS_CHECK_TTS_DATA intent to prefix them with EXTRA_. Cleaned up the other TextToSpeech.Engine constant to remove superfluous mentions of "TTS" in the name.
