如下所示，Google 为 TTS 创建了一组新的 API。因此，使用预览实现创建的应用程序将停止在 ICS 中工作：
http:// developer.android.com/reference/android/speech/tts/TextToSpeech.html
上面的链接表示我们应该寻找带有兼容层的博客文章，以防万一我们需要向后兼容。
有谁知道我们如何使用新指南实现 TTS 而不破坏向后兼容性？
任何帮助表示赞赏。
最好的问候，
卡洛斯
As you can see below, Google has created a new set of APIs for TTS. So, apps created using previews implementantions will stop working in ICS:
http://developer.android.com/reference/android/speech/tts/TextToSpeech.html
The link above says we should look for a blog post with a compatibility layer just in case we need to havesome backwards compatibility.
Does anyone knows how we can implement TTS using the new guidelines WITHOUT breaking backwards compatibility?
Any help is appreciated.
Best regards,
Carlos

我使用 Svox 并注意到在 ics 中唯一的默认引擎似乎是 google tts。
我跳回我的姜饼手机，默认 svox 工作正常，因为设置允许我选择 pico 或 svox 作为默认设置。
不幸的是，在 ics 中，虽然您可以设置“首选 tts 引擎”
相比之下，在姜饼中，设置/语音输入和输出/文本转语音设置可用于设置默认 tts 引擎。
因此，我最终得到了某些应用程序，例如使用 svox“首选 tts”的语音警报，但其他程序则不会，除非它是 google tts。
为什么要把这个复杂化以使其更适合 D. ？
如果我们愿意的话，为什么不直接将其设为默认值并让应用程序覆盖......首选是 vaque。他们在姜饼中就已经做到了……为什么要倒退呢？
I use Svox and have noticed that in ics the only default engine seems to be google tts.
I jump back to my gingerbread phone and have svox working fine as the default because the settings allow me to chose pico or svox as the default.
Unfortunately in ics , while you can set the 'preferred tts engine'
In gingerbread by contrast, the settings/voice input & output/text to speech settings can be used to set the default tts engine.
So I end up with certain apps like voice alerts using the svox 'preferred tts' but other programs wount unless it is google tts.
WHY COMPLICATE THIS TO MAKE IT P R E F F E R E D. ?
WHY NOT JUST MAKE IT D E F A U L T and have apps override if we want to....preferred is to vaque. they had it right in gingerbreat...why go backwards ?
我认为您的声明“因此，使用预览实现创建的应用程序将停止在 ICS 中工作：”（我猜您的意思是“先前”而不是“预览”）具有误导性。
我使用 Android 2.2 构建的应用程序在 API 15 模拟器上完美地合成了语音。我希望它在真实设备上也能正常工作。
有几个已弃用方法，但这仅意味着这些方法可能在未来版本中被删除，并不是说它们在当前版本中不起作用。这只是一个警告，表明现在有更新更好的方法可用。
I think your statement "So, apps created using previews implementantions will stop working in ICS:" ( I guess you meant 'previous' not 'previews') is misleading.
My app built with Android 2.2 synthesises speech perfectly well on an API 15 emulator. I would expect it to work just as well on a real device.
There are a couple of deprecated methods but this just means that these methods may be removed in a future version, not that they won't work in the current version. It's just a warning that there are newer and better methods now available.
