ios ml 深度学习做字幕

1:使用前需要导入头文件

importSpeech

2:设置请求权限

//请求权限
        SFSpeechRecognizer.requestAuthorization { (state) in
           print(state)
        }

3:配置info.plist

Privacy-Speech Recognition Usage Description   -> “xxx”

4:初始化识别器

//初始化一个识别器

letrecognizer = SFSpeechRecognizer(locale: Locale(identifier: "zh_CN”))

代码

   assert(status == .authorized)            DispatchQueue.main.async {            }                        //path            let url = Bundle.main.url(forResource: "video", withExtension: "mp4")                        //初始化一个识别请求            let request = SFSpeechURLRecognitionRequest(url: url!)                        //开始一个识别请求            self.speechRecognizer.recognitionTask(with: request, resultHandler: { (result, error) in                if error != nil{                    print("识别错误")                    return                }                else{                    print(result?.bestTranscription.formattedString)                }            })        }
