ios - 有没有办法在离线模式下使用 iOS 语音识别？

Question

我想知道是否有办法在离线模式下使用 iOS 语音识别。根据文档 ( https://developer.apple.com/reference/speech )，我没有看到任何相关内容。

Answer 1

恐怕没办法做到(但是，请确保在答案末尾检查更新)。

如 Speech Framework Official Documentation 所述:

Best Practices for a Great User Experience:

Be prepared to handle the failures that can be caused by reaching speech recognition limits. Because speech recognition is a network-based service, limits are enforced so that the service can remain freely available to all apps.

从最终用户的角度来看，尝试在不连接到网络的情况下获得 Siri 的帮助应该显示类似于以下的屏幕:

此外，当尝试发送消息时 - 例如 - 如果设备未连接到网络，您会注意到麦克风按钮应该被禁用。

iOS 本身在检查网络连接之前无法使用此功能，我假设第三方开发人员在使用 Speech Framework 时也是如此。

更新:

看完Speech Recognition API Session (尤其是 03:00 - 03:25 部分)，我想出了:

语音识别 API 通常 需要互联网连接，但有些新设备始终支持此功能；您可能想检查给定的语言是否可用。

改编自SFSpeech​Recognizer Documentation :

Note that a supported speech recognizer is not the same as an available speech recognizer; for example, the recognizers for some locales may require an Internet connection. You can use the supported​Locales() method to get a list of supported locales and the is​Available property to find out if the recognizer for a specific locale is available.
