I need a simple Google Speech API example for .NET in which I upload a voice file and receive the text. Thanks.

Just worked for me, you can create a class as follow:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
namespace GoogleAPI{
public class GoogleSpeech
{
public string URL { get; set; }
public void GetSpeechTranscript(string filePath)
{
try
{
FileStream fileStream = File.OpenRead(filePath);
MemoryStream memoryStream = new MemoryStream();
memoryStream.SetLength(fileStream.Length);
fileStream.Read(memoryStream.GetBuffer(), 0, (int)fileStream.Length);
byte[] resBytes = memoryStream.GetBuffer();
HttpWebRequest request = null;
request = (HttpWebRequest)HttpWebRequest.Create(this.URL + "&key=YOUR_API_KEY");
request.Credentials = CredentialCache.DefaultCredentials;
request.Method = "POST";
request.ContentType = "audio/x-flac; rate=44100";
request.ContentLength = resBytes.Length;
Stream stream = request.GetRequestStream();
stream.Write(resBytes, 0, resBytes.Length);
stream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
StreamReader reqStream = new StreamReader(response.GetResponseStream());
var result = reqStream.ReadToEnd();
Console.WriteLine(result);
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
Console.ReadLine();
}
}
}
Hope this help!
