设备上的语音识别是一件事吗?

iOS 13的新功能,您应该可以这样说(import Speech

let req = SFSpeechAudioBufferRecognitionRequest()
let loc = Locale(identifier: "en-US")
guard let rec = SFSpeechRecognizer(locale:loc)
    else {print("no recognizer"); return}
print("rec isAvailable says: \(rec.isAvailable)")
if rec.supportsOnDeviceRecognition {
    print("on device recognition")
    req.requiresOnDeviceRecognition = true
} else {
    print("no on device recognition")
}

问题是我在所有设备上都收到"no on device recognition"。我可以做语音识别。我只是无法在设备上进行语音识别。此功能是真实的,还是Apple的理想?

您可能在13.1上遇到supportsOnDeviceRecognition的已知问题。来自iOS/iPadOS 13.1 Release Notes

  

supportsOnDeviceRecognition属性在首次访问时始终返回false。几秒钟后,再次访问它会返回正确的值。 (47822242)
