абстрактный метод "com.google.api.gax.tracing.ApiTracer" ошибка от TextToSpeechApi, как ее решить?

Question

Я использую TextToSpeechApi для чтения текста с несколькими языками и голосами.Но он показывает java.lang.AbstractMethodError: ошибку в строке SynthesizeSpeechResponse.Как решить эту проблему.

Мой gradle:

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'

implementation 'com.google.cloud:google-cloud-translate:1.65.0'
// add these dependencies for the speech client
implementation 'io.grpc:grpc-okhttp:1.10.0'
implementation 'com.google.cloud:google-cloud-speech:0.53.0-alpha'
implementation 'com.google.cloud:google-cloud-texttospeech:0.53.0-beta'

implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'
}

Мой Java Код:

private static final String TAG = "TextReadCloudApi";

    super.onCreate(savedInstanceState);

    Button button = (Button) findViewById(R.id.readBtn);

    button.setOnClickListener(new View.OnClickListener() {

                // Write the response to the output file.
