swift - SFSpeechRecognizer 失败并出现错误 kAFAssistantErrorDomain Code=1107

Question

我正在尝试在我的应用程序中转录本地音频文件。短文件识别良好，但如果音频超过 15 分钟，则不是。控制台立即显示此错误：

2020-01-17 12:57:07.528986+0300 App[2816:791131] [Utility] +[AFAggregator logDictationFailedWithError:] Error Domain=kAFAssistantErrorDomain Code=1107 "(null)"

这是我的代码：

        let localRecognitionRequest = SFSpeechURLRecognitionRequest(url: fileUrl)
        localRecognitionRequest.shouldReportPartialResults = false
        if speechRecognizer.supportsOnDeviceRecognition {
            localRecognitionRequest.requiresOnDeviceRecognition = true
        }
        recognitionTask = speechRecognizer.recognitionTask(with: localRecognitionRequest, delegate: self)

当出现错误时，只会触发一个委托方法：

    func speechRecognitionTask(_ task: SFSpeechRecognitionTask, didFinishSuccessfully successfully: Bool) { }

和successfully = false

我有 Xcode 11.3.1

仅在设备上试用 - iPhone XS (iOS 13.3)

有没有人遇到过这个问题？
