Swift -如何从语音中保存文本文件

import Speech

SFSpeechRecognizer.requestAuthorization { (authStatus) in
    if authStatus == .authorized {
        // 用户已授权，可以进行语音识别
    }
}

let recognizer = SFSpeechRecognizer()

let request = SFSpeechURLRecognitionRequest(url: audioFileURL)

recognizer.recognitionTask(with: request) { (result, error) in
    if let result = result {
        let transcription = result.bestTranscription.formattedString
        // 将转录的文本保存为文件
        saveTranscriptionToFile(transcription)
    } else if let error = error {
        // 处理错误
    }
}

func saveTranscriptionToFile(_ transcription: String) {
    let fileURL = // 创建保存文件的URL
    do {
        try transcription.write(to: fileURL, atomically: true, encoding: .utf8)
        // 文件保存成功
    } catch {
        // 处理保存文件失败的情况
    }
}
