Google Speech API - 无响应且DEADLINE_EXCEEDED

Question

我使用以下java代码来调用Google Cloud语音API，但我没有得到任何回复，有时甚至是DEADLINE_EXCEEDED消息

注意：这适用于家庭wi-fi，仅在公司网络中我看到此问题。任何指针都非常感激

如果我错过了什么，请告诉我。此外，对于身份验证部分，我如何验证它是否经过身份验证？

   FileInputStream credentialsStream = new FileInputStream("C:/service-account-file.json");
    GoogleCredentials credentials = GoogleCredentials.fromStream(credentialsStream);
    FixedCredentialsProvider credentialsProvider = FixedCredentialsProvider.create(credentials);

    SpeechSettings speechSettings = 
            SpeechSettings.newBuilder()
                .setCredentialsProvider(credentialsProvider)
                .build();       


    // Instantiates a client

    SpeechClient speechClient = SpeechClient.create(speechSettings);    


        RecognitionConfig.AudioEncoding encoding = RecognitionConfig.AudioEncoding.FLAC;
            int sampleRateHertz = 16000;
            String languageCode = "en-US";
            RecognitionConfig config = RecognitionConfig.newBuilder()
              .setEncoding(encoding)
              .setSampleRateHertz(sampleRateHertz)
              .setLanguageCode(languageCode)
              .build();

             String fileName = "C:\\Hello.flac";

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

              RecognitionAudio audio = RecognitionAudio.newBuilder()
                .setContent(audioBytes)
                .build();


             RecognizeResponse response = speechClient.recognize(config, audio);


            List<SpeechRecognitionResult> results = response.getResultsList();

            for (SpeechRecognitionResult result: results) {
              // There can be several alternative transcripts for a given chunk of speech. Just use the
              // first (most likely) one here.
              SpeechRecognitionAlternative alternative = result.getAlternativesList().get(0);
              System.out.printf("Transcription: %s%n", alternative.getTranscript());
            }
            speechClient.close();
    }catch(Exception e){
        e.printStackTrace();
    }
