我想使用谷歌云语音应用程序接口和安卓应用程序，我正在使用这个链接，由谷歌 https://cloud.google.com/speech-to-text/docs/libraries#client-libraries-install-java 提供

我已经尝试了link https://developers.google.com/accounts/docs/application-default-credentials 中提供的解决方案，但它仍然不起作用。

Windows环境变量用户和系统都有GOOGLE_APPLICATION_CREDENTIALS=C:\Users\ANSH\Downloads\credential.json

所有必要的导入都已准备就绪。

 private void recognizeSpeech(){
        SpeechClient speechClient = SpeechClient.create();
        String languageCode="en-US";
        int sampleRateHertz=16000;
        RecognitionConfig.AudioEncoding encoding = RecognitionConfig.AudioEncoding.LINEAR16;
        RecognitionConfig config =
                RecognitionConfig.newBuilder()
                        .setLanguageCode(languageCode)
                        .setSampleRateHertz(sampleRateHertz)
                        .setEncoding(encoding)
                        .build();
        Path path = Paths.get(fileName);
        byte[] data = Files.readAllBytes(path);
        ByteString content = ByteString.copyFrom(data);
        RecognitionAudio audio = RecognitionAudio.newBuilder().setContent(content).build();
        RecognizeRequest request =
                RecognizeRequest.newBuilder().setConfig(config).setAudio(audio).build();
        RecognizeResponse response = speechClient.recognize(request);
        for (SpeechRecognitionResult result : response.getResultsList()) {
            // First alternative is the most probable result
            SpeechRecognitionAlternative alternative = result.getAlternativesList().get(0);
            outputText.setText(alternative.getTranscript());
