PCM文件大小400K，时长10s左右。 识别结果需要7-8s，这个时长完全接受不了啊

代码如下：

aip::get_file_content("D:\\pcm\\test.pcm", &file_content);

clock_t start = clock();
std::cout << "recognize start :" << start<Json::Value result = client->recognize(file_content, "pcm", 16000, options);
clock_t ends = clock();
std::cout << "recognize end" <cout << "client->recognize  Running Time : " << (double)(ends - start) / CLOCKS_PER_SEC << endl;
