百度语音api调用

这周是第六周。

本周使用百度的api调用，利用线程池容纳线程进行语音的分析，这样不会因为语音太多而造成卡顿或者造成速度下降等问题。

调用百度api,

设置请求参数和secret和secret_key,

接收返回的数据.

import java.util.List;

public class voice_recog {

			String baidu_id,String baidu_key,String baidu_secret)
	{
		ArrayList list=new ArrayList();
		//Calendar calendar=Calendar.getInstance();
		//System.out.println(calendar.getTime().toString());
        AipSpeech client = new AipSpeech(baidu_id,baidu_key,baidu_secret);

        // 可选：设置网络连接参数
        client.setConnectionTimeoutInMillis(2000);
        client.setSocketTimeoutInMillis(60000);

        // 调用接口
        JSONObject res = client.asr(file, type, 8000, null);
        //System.out.println(res.toString(2));
        //calendar=Calendar.getInstance();
        //System.out.println(calendar.getTime().toString());
        JSONArray jsonarr= res.getJSONArray("result");
