Google SpeechClient API

Question

I am trying to do some work using the Google Speech API. How can I specify the authentication keys using the Google Speech API Java library? I am using this method Google Speech API credentials

I want to convert audio file into text

Thank you

CredentialsProvider credentialsProvider = FixedCredentialsProvider.create(ServiceAccountCredentials.fromStream(new FileInputStream("home/hussain/AndroidStudioProjects/NestedLogics/RouteApplication/service-account.json")));

        SpeechSettings settings = SpeechSettings.newBuilder().setCredentialsProvider(credentialsProvider).build();
        //SpeechClient speechClient = SpeechClient.create(settings);
        SpeechClient speech = SpeechClient.create(settings);

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            Path path = Paths.get(file_path);
            byte[] data = Files.readAllBytes(path);
            ByteString audioBytes = ByteString.copyFrom(data);
            RecognitionConfig config = RecognitionConfig.newBuilder()
                    .setEncoding(RecognitionConfig.AudioEncoding.LINEAR16)
                    .setSampleRateHertz(16000)
                    .setLanguageCode("en-US")
                    .build();
            RecognitionAudio audio = RecognitionAudio.newBuilder()
                    .setContent(audioBytes)
                    .build();

            RecognizeResponse response = speech.recognize(config,audio);
            List<SpeechRecognitionResult> results = response.getResultsList();
            for (SpeechRecognitionResult result: results)
            {
                SpeechRecognitionAlternative alternative = result.getAlternativesList().get(0);
                Log.d("HOME", "convertAudioToSpeech: "+alternative.getTranscript());
            }
        }

Are you using the Google Cloud SDK?

After you generated a JSON file with credentials, put it under app/src/main/res/raw/credential.json in the Android project sources. And then in the speech service creating code:

InputStream stream = getContext().getResources().openRawResource(R.raw.credential);                   
SpeechSettings settings =
  SpeechSettings.newBuilder().setCredentialsProvider(
    new CredentialsProvider() {
      @Override
      public Credentials getCredentials() throws IOException {
        return GoogleCredentials.fromStream(stream);
      }
    }
  ).build();

i tried this but i got an error Caused by: java.lang.NoSuchMethodError: No direct method <init>(Lcom/google/api/gax/rpc/ClientContext;)V in class Lcom/google/api/gax/rpc/ClientSettings$Builder; or its super classes (declaration of 'com.google.api.gax.rpc.ClientSettings$Builder' appears in /data/app/com.example.hussain.routeapplication-BtQ8fKEs7dp_ENQO4aatuw==/split_lib_dependencies_apk.apk) at com.google.cloud.speech.v1.SpeechSettings$Builder.<init>(SpeechSettings.java:259)

It's hard to say just from this error message. Highly likely, it's a problem with dependencies, so check that your gradle configs look exactly like in the sample application.

Or may be you're using an outdated version of google-cloud-speech. Mine is implementation 'com.google.cloud:google-cloud-speech:0.41.0-alpha'

Alexander.. build.gradle is up there.

@hussainabbas I recommend to change the dependency version from 0.30.0 to 0.41.0-alpha

I don't have much experience with the Google Cloud SDK but from what I understand you should:

Create the project under the Google Cloud Services.

After you create the project and set up a payment method (as this service is not free) you will be able to download a private key in the form of a JSON file.

You then need to set up an environment variable name GOOGLE_APPLICATION_CREDENTIALS on your machine to point to that file. Then you should be ready to go.

You can read a detailed step by step how to here.
