无法调用SpeechClient.recognize(RecognizeRequest请求):抛出异常 [英] Cannot call SpeechClient.recognize(RecognizeRequest request): Throwing Exception
问题描述
这是我第一次发布,因此我对规则不太熟悉,但是可以。
我一直在尝试使Google Cloud Speech API在Android上运行,但无济于事。相同的代码在Java上可以正常工作,但在Android上却不能。
我的代码可以正常运行,直到使用语音客户端调用Recognition方法为止。
这是错误:
This is my first time posting, so I'm not too familiar with the rules, but here goes. I've been trying to get the Google Cloud Speech API to work on Android, but to no avail. The same code works just fine on Java, but not on Android. My code runs fine until I call the recognize method, using a speech client. Here is the error:

我不知道为什么会这样。这是我的代码:
I don't know why this is happening. Here is my code:
package capstone.speechrecognitionsimple;

public class MainActivity extends AppCompatActivity {

init.execute();
}
class InitTask extends AsyncTask<ByteString, Void, String> {
SpeechClient speechClient = null;
protected String doInBackground(ByteString... strings) {
String transcript = "Transcript:\n";
try {
Log.i("InitTask", "Creating client...");
InputStream credentialsStream = getAssets().open("credentials.json");
GoogleCredentials credentials = GoogleCredentials.fromStream(credentialsStream);
FixedCredentialsProvider credentialsProvider = FixedCredentialsProvider.create(credentials);

byte[] data = IOUtils.toByteArray(path);
ByteString audioBytes = ByteString.copyFrom(data);
SpeechSettings speechSettings =
SpeechSettings.newBuilder()
.setCredentialsProvider(credentialsProvider)
.build();
Log.i("InitTask", "Settings Created");
speechClient = SpeechClient.create(speechSettings);
Log.i("InitTask", "Client Created");
RecognitionConfig.AudioEncoding encoding = RecognitionConfig.AudioEncoding.LINEAR16;
Log.i("InitTask", "Encoding Created");
int sampleRateHertz = 16000;
String languageCode = "en-US";
RecognitionConfig config = RecognitionConfig.newBuilder()
.setEncoding(encoding)
.setSampleRateHertz(sampleRateHertz)

.build();

for (SpeechRecognitionResult result : results) {

for (SpeechRecognitionAlternative alternative : alternatives) {
transcript+= alternative.getTranscript();
}
}
}
catch(Exception e){
Log.e("Client", "" + e.toString());
e.printStackTrace();
}
try {
speechClient.close();
} catch (Exception e) {
Log.e("Client", "" + e.toString());
e.printStackTrace();
}
return transcript;
}
protected void onPostExecute(String transcript) {
Log.i("Transcript", "" +transcript);
}
}
}

推荐答案
我在Protobuf中遇到了同样的问题。对于遇到此问题的其他人,请确保您在顶级build.gradle中具有以下内容:
I had the same issue with Protobuf. For others running into this issue, make sure you have the following in your top-level build.gradle:
classpath'com.google.protobuf:protobuf-gradle-plugin :0.8.6'
classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.6'
