Question

我使用的是iOS 13的语音识别，但没有返回正确的讲话率，平均暂停时间或语音分析。

正确打印了口语单词，但这是我打印出的段信息：

segment：，substringRange = {0，2}，时间戳= 0，持续时间= 0，置信度= 0，子字符串=因此， AlternativeSubstrings =（），phoneSequence =，ipaPhoneSequence =， voiceAnalytics =（null）

感谢您的帮助！

func startSpeechRecognition() throws{

    if let recognitionTask = recognitionTask {
        recognitionTask.cancel()
        self.recognitionTask = nil
    }

    try audioSession.setCategory(AVAudioSessionCategoryPlayAndRecord)
    try audioSession.setMode(AVAudioSessionModeMeasurement)
    try audioSession.setActive(true, with: .notifyOthersOnDeactivation)

    recognitionRequest = SFSpeechAudioBufferRecognitionRequest()
    let inputNode = audioEngine.inputNode

    if speechRecognizer.supportsOnDeviceRecognition {
        print("support on device recognition")
        recognitionRequest?.requiresOnDeviceRecognition = true
    }

    guard let recognitionRequest = recognitionRequest else {
        fatalError("Unable to created a SFSpeechAudioBufferRecognitionRequest object")
    }

    recognitionTask = speechRecognizer.recognitionTask(with: recognitionRequest) { result, error in

        if let result = result {
            let bestString = result.bestTranscription.formattedString
            self.spokenWords = bestString
            if self.spokenWords != nil{
                self.numberOfWordsRecorded = self.spokenWords!.components(separatedBy: .whitespacesAndNewlines).count
                print(bestString)
            }

            for segment in result.bestTranscription.segments {
                print("segment: \(segment)")
            }
        }
    }
}

最终的工作是从

更改SFSpeechRecognizer的语言环境。

var speechRecognizer = SFSpeechRecognizer(locale: Locale(identifier: "en_US"))!

到

var speechRecognizer = SFSpeechRecognizer(locale: Locale(identifier: "en-US"))!

语音识别语音分析返回Null（Swift iOS 13）
