iOS 10.0 Speech Recognition Error kAFAssistantErro

问题:

I try using speech recognition as below

    let urlpath = Bundle.main().pathForResource("myvoice2", ofType: "m4a")
    let url:URL = URL.init(fileURLWithPath: urlpath!)

    let recognizer = SFSpeechRecognizer()
    let request = SFSpeechURLRecognitionRequest(url: url)
    recognizer?.recognitionTask(with: request, resultHandler: { (result, error) in
        print (result?.bestTranscription.formattedString)

    })

The result is nil, I debug and see the error as below

Error Domain=kAFAssistantErrorDomain Code=1101 "(null)"

Do you have any idea?

回答1:

I have the same error, but identical code worked fine on device. So, install iOS 10 beta on a physical device and run your code. Something like this ought to do the trick:

SFSpeechRecognizer.requestAuthorization { authStatus in
    if authStatus == SFSpeechRecognizerAuthorizationStatus.authorized {
        if let path = Bundle.main().urlForResource("test", withExtension: "m4a") {
            let recognizer = SFSpeechRecognizer()
            let request = SFSpeechURLRecognitionRequest(url: path)
            recognizer?.recognitionTask(with: request, resultHandler: { (result, error) in
                if let error = error {
                    print("There was an error: \(error)")
                } else {
                    print (result?.bestTranscription.formattedString)
                }
            })
        }
    }
}
