SFTranscriptionSegment的时间戳始终为0 [英] SFTranscriptionSegment's timestamp is always 0

问题描述

这是有关新的iOS 10语音框架的提问.我使用以下方法获得语音识别结果

This is a questoin regarding new iOS 10 Speech framework. I get the speech recognition result using following method

 recognitionTask =   [speechRecgzr recognitionTaskWithRequest:recognitionRequest resultHandler:^(SFSpeechRecognitionResult * _Nullable result, NSError * _Nullable error) {

    }

但是结果中每个SFTranscriptionSegment的时间戳为0，置信度始终为0

But the timestamp of each SFTranscriptionSegment in result is 0 and also confidence is always 0

这里可能是什么问题?苹果还没有正确实现API吗?

What can be the problem here? Have apple not implemented the API properly yet?

谢谢.

推荐答案

几周后，我发现通过设置此项可以得到时间戳和置信度:

After few weeks I found that by setting this I can get timestamp and confidence:

speechRecgzr.defaultTaskHint = SFSpeechRecognitionTaskHintDictation;
