print('$volume');
},
onResults: (String result, isLast) {
print(result.toString());
},
onCompleted: (Map<dynamic, dynamic> errInfo, String filePath) {
print('onCompleted');
}
);
voice.start(listener: listener);

The result type is based on the parameter result_type you setted before. It may be json/xml/plain.
