推荐答案

我从事过对我有用的相同工作.

I have worked on same things which are working for me.

我的项目包中有音频文件.因此，我编写了以下代码将音频转换为文本.

I have audio file in my project bundle which. So I have written following code to convert audio to text.

let audioURL = Bundle.main.url(forResource: "Song", withExtension: "mov")

let recognizer = SFSpeechRecognizer(locale: Locale(identifier: "en-US"))
let request = SFSpeechURLRecognitionRequest(url: audioURL!)

request.shouldReportPartialResults = true

if (recognizer?.isAvailable)! {

    recognizer?.recognitionTask(with: request) { result, error in
        guard error == nil else { print("Error: \(error!)"); return }
        guard let result = result else { print("No result!"); return }

        print(result.bestTranscription.formattedString)
    }
} else {
    print("Device doesn't support speech recognition")
}

首先从存储音频文件的位置获取音频URL. 然后使用所需的语言环境创建SFSpeechRecognizer的实例. 创建用于请求recognitionTask的SFSpeechURLRecognitionRequest实例.

First get audio url from where you have store audio file. Then create instance of SFSpeechRecognizer with locale that you have want. Create instance of SFSpeechURLRecognitionRequest which are used to requesting recognitionTask.

recognitionTask将给您结果和错误.结果包含bestTranscription.formattedString. formmatedString是音频文件的测试结果.

recognitionTask will give you result and error. Where result contains bestTranscription.formattedString. formmatedString is your test result of audio file.

如果设置为request.shouldReportPartialResults = true，则将给出每行音频通话的部分结果.

If set request.shouldReportPartialResults = true, this will give your partial result of every line speak in audio.

我希望这会对您有所帮助.
