,.net平台,发送http请求,调用百度API,进行语音翻译,翻译能力为中文,英语,粤语,请看百度语音识别文档.
这里我只贴出了http部分的代码,,也是最关键的,,希望大家多提意见,,优化代码

public string API_id = "你的ID";
public string API_record = null;
public string API_record_format = null;
public string API_record_HZ = null;
public string API_key = "你的KEY";
public string API_secret_key = "你的SECRRET_KEY";
public string API_language = null;
public string API_access_token=null;
public string strJSON = "";

public string getStrAccess(string para_API_key, string para_API_secret_key)
{

//方法参数说明:
//para_API_key:API_key(你的KEY)
//para_API_secret_key(你的SECRRET_KEY)

//方法返回值说明:
//百度认证口令码,access_token
string access_html = null;
string access_token = null;
string getAccessUrl = "https://openapi.baidu.com/oauth/2.0/token?grant_type=client_credentials" +
"&client_id=" + para_API_key + "&client_secret=" + para_API_secret_key;
try
{
HttpWebRequest getAccessRequest = WebRequest.Create(getAccessUrl) as HttpWebRequest;
//getAccessRequest.Proxy = null;
getAccessRequest.ContentType = "multipart/form-data";
getAccessRequest.Accept = "*/*";
getAccessRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)";
getAccessRequest.Timeout = 30000;//30秒连接不成功就中断
getAccessRequest.Method = "post";

HttpWebResponse response = getAccessRequest.GetResponse() as HttpWebResponse;
using (StreamReader strHttpComback = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
access_html = strHttpComback.ReadToEnd();
}
}
catch (WebException ex)
{
MessageBox.Show(ex.ToString());
}

JObject jo = JObject.Parse(access_html);
access_token = jo["access_token"].ToString();//得到返回的toke
return access_token;
}

public string getStrText(string para_API_id, string para_API_access_token,string para_API_language, string para_API_record,string para_format,string para_Hz)
{
//方法参数说明:
para_API_id: API_id (你的ID)
para_API_access_token (getStrAccess(...)方法得到的access_token口令)
para_API_language (你要识别的语言,zh,en,ct)
para_API_record(语音文件的路径)
para_format(语音文件的格式)
para_Hz(语音文件的采样率 16000或者8000)

//该方法返回值:
//该方法执行正确返回值是语音翻译的文本,错误是错误号,可以去看百度语音文档,查看对应错误

string strText = null;
string error = null;
FileInfo fi = new FileInfo(para_API_record);
FileStream fs = new FileStream(para_API_record, FileMode.Open);
byte[] voice = new byte[fs.Length];
fs.Read(voice, 0, voice.Length);
fs.Close();

string getTextUrl = "http://vop.baidu.com/server_api?lan=" + para_API_language + "&cuid=" + para_API_id + "&token=" + para_API_access_token;
HttpWebRequest getTextRequst = WebRequest.Create(getTextUrl) as HttpWebRequest;

/* getTextRequst.Proxy = null;
getTextRequst.ServicePoint.Expect100Continue = false;
getTextRequst.ServicePoint.UseNagleAlgorithm = false;
getTextRequst.ServicePoint.ConnectionLimit = 65500;
getTextRequst.AllowWriteStreamBuffering = false;*/

getTextRequst.ContentType = "audio /"+para_format+";rate="+para_Hz;
getTextRequst.ContentLength = fi.Length;
getTextRequst.Method = "post";
getTextRequst.Accept = "*/*";
getTextRequst.KeepAlive = true;
serverreq.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)";
getTextRequst.Timeout = 30000;//30秒连接不成功就中断
using (Stream writeStream = getTextRequst.GetRequestStream())
{
writeStream.Write(voice, 0, voice.Length);
}

HttpWebResponse getTextResponse = getTextRequst.GetResponse() as HttpWebResponse;
using (StreamReader strHttpText = new StreamReader(getTextResponse.GetResponseStream(), Encoding.UTF8))
{
strJSON = strHttpText.ReadToEnd();
}
JObject jsons = JObject.Parse(strJSON);//解析JSON
if (jsons["err_msg"].Value<string>() == "success.")
{
strText = jsons["result"][0].ToString();
return strText;
}
else
{
error = jsons["err_no"].Value<string>() + jsons["err_msg"].Value<string>();
return error;
}

}
