我正在尝试在我的spring boot应用程序中使用javasdkforjava从gcp语音到文本api得到json响应，然后将其传递到angular前端以得到显示。但问题是google doc建议回复类似于gcp doc link

{
  "results": [
    {
      "alternatives": [
        {
          "transcript": "how old is the Brooklyn Bridge",
          "confidence": 0.98360395,
          "words": [
            {
              "startTime": "0s",
              "endTime": "0.300s",
              "word": "how",
              "confidence": SOME NUMBER
            },
            ...
          ]
        }
      ]
    }
  ]
}

但是当我调用speechclient.recognize并尝试使用gsn库将其转换为json时，如下所示

Path path = Paths.get(fileName);
            byte[] data = Files.readAllBytes(path);
            ByteString audioBytes = ByteString.copyFrom(data);

            // Builds the sync recognize request
            RecognitionConfig config =
                    RecognitionConfig.newBuilder()
                            .setEncoding(AudioEncoding.LINEAR16)
                            .setLanguageCode("en-US")
                            .setEnableWordConfidence(true)
                            .setEnableWordTimeOffsets(true)
                            .build();
            RecognitionAudio audio = RecognitionAudio.newBuilder().setContent(audioBytes).build();

            // Performs speech recognition on the audio file
            response = speechClient.recognize(config, audio);
            Gson gson = new GsonBuilder().setPrettyPrinting().create();

            logger.error(gson.toJson(response));

            file.write(gson.toJson(response));

            file.flush();
            file.close();

这是文件里写的

所有这些额外的东西加上结尾的“\”是不希望有人能帮我的。
谢谢
