external/svox/pico/src/com/svox/pico/PicoService.java (AOSP默认值)尝试运行CTS，但结果在oero中失败

Question

我正在尝试在默认的AOSP TTS引擎上运行CTS。但是，cts仍然会因为以下命令而失败:为语音运行CTS运行cts --skip-device-info --skip-preconditions -disable-reboot --module CtsSpeechTestCases

模块通过失败的总测试完成x86 CtsSpeechTestCases 4 5 9 true x86_64 CtsSpeechTestCases 3 6 9 true

onUtteranceCompleted(String utteranceId)未取消，在oero中使用UtteranceProgressListener。

aosp默认TTS引擎出现故障的原因

Failed CTS cases:
android.speech.tts.cts.TextToSpeechTest#testSpeak
android.speech.tts.cts.TextToSpeechTest#testSpeakStop
android.speech.tts.cts.TextToSpeechTest#testSynthesizeToFile

We can also reproduce this NE by following steps:
1. Go to Accessibility Settings
2. Select Text to speech output
3. Click play

Analysis:
Exception occurs due to calculation of
picokpr_getAttrValArrInt32(...) is incorrect. The logic here
intends to clear the MSB and return the rest of the bits. We
found if library compiled in Android N environment the result
of comparison operation is different from library compiled in
Android O environment. In Android O, actual returne value doesn't
process the value and returns as it is. This causes invalid
pointer access and hence native exception due to segmentation fault.

Solution: Changed to use bitwise shift instead.

Bug: 64204643
Test: After applying this patch, CTS cases can pass and exception
can be fixed.
