Apple Speech API - SFTranscriptionSegment具有相同的置信度值

Question

我注意到使用Apple Speech Framework的一种奇怪行为。

在我自己的应用程序中实现并使用Apple和在线提供的示例后，我注意到语音框架总是在语音检测结果后为每个转录段返回相同的置信度。

以下是我在本Q底部使用原始转储执行的测试的格式化数据，您会注意到，对于每个SFTranscription，索引的段具有相同的置信度值，尽管具有不同转录的不同对象。

我认为这是不正确的，因为它在文档中说，结果是自信地排序，首先是最自信的。

如果有人知道对此有所修正，或者可以将我指向明确承认存在问题的地方，那将是最有帮助的。
