我正在努力执行续.AVCapture在iOS 10 beta上使用语音识别.我已经设置captureOutput(...)了不断获得CMSampleBuffers.我将这些缓冲区直接放入SFSpeechAudioBufferRecognitionRequest我之前设置的中,如下所示:

... do some setup
  SFSpeechRecognizer.requestAuthorization { authStatus in
    if authStatus == SFSpeechRecognizerAuthorizationStatus.authorized {
      self.m_recognizer = SFSpeechRecognizer()
      self.m_recognRequest = SFSpeechAudioBufferRecognitionRequest()
      self.m_recognRequest?.shouldReportPartialResults = false
      self.m_isRecording = true
    } else {
      print("not authorized")
    }
  }
.... do further setup


func captureOutput(_ captureOutput: AVCaptureOutput!, didOutputSampleBuffer sampleBuffer: CMSampleBuffer!, from connection: AVCaptureConnection!) {

if(!m_AV_initialized) {
  print("captureOutput(...): not initialized !")
  return
}
if(!m_isRecording) {
  return
}

let formatDesc = CMSampleBufferGetFormatDescription(sampleBuffer)
let mediaType = CMFormatDescriptionGetMediaType(formatDesc!)
if (mediaType …

有谁知道iOS 10(每台设备或每个应用程序)的语音识别是否有限制？
