用于语音识别的 IOS Swift 3 [关闭]

Question

我正在做我的语音识别项目。录制代码运行良好，但我们不知道如何编写代码将音频存储在 firebase 中。

你能帮我写代码吗？

class SpeechViewController: UIViewController,AVAudioPlayerDelegate,AVAudioRecorderDelegate {
     var usersStorageRef: FIRStorageReference!
    var audioPlayer: AVAudioPlayer?
    var audioRecorder: AVAudioRecorder?
    private let speechRecognizer = SFSpeechRecognizer(locale:
        Locale(identifier: "en-US"))!

private var speechRecognitionRequest:
SFSpeechAudioBufferRecognitionRequest?
private var speechRecognitionTask: SFSpeechRecognitionTask?
private let audioEngine = AVAudioEngine()
