How to use google speech recognition api in c#?
Just tested this myself, below is a working solution if you have a valid API key.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
using System.IO;
namespace GoogleRequest
{
class Program
{
static void Main(string[] args)
{
try
{
FileStream fileStream = File.OpenRead("good-morning-google.flac");
MemoryStream memoryStream = new MemoryStream();
memoryStream.SetLength(fileStream.Length);
fileStream.Read(memoryStream.GetBuffer(), 0, (int)fileStream.Length);
byte[] BA_AudioFile = memoryStream.GetBuffer();
HttpWebRequest _HWR_SpeechToText = null;
_HWR_SpeechToText =
(HttpWebRequest)HttpWebRequest.Create(
"https://www.google.com/speech-api/v2/recognize?output=json&lang=en-us&key=YOUR_API_KEY_HERE");
_HWR_SpeechToText.Credentials = CredentialCache.DefaultCredentials;
_HWR_SpeechToText.Method = "POST";
_HWR_SpeechToText.ContentType = "audio/x-flac; rate=44100";
_HWR_SpeechToText.ContentLength = BA_AudioFile.Length;
Stream stream = _HWR_SpeechToText.GetRequestStream();
stream.Write(BA_AudioFile, 0, BA_AudioFile.Length);
stream.Close();
HttpWebResponse HWR_Response = (HttpWebResponse)_HWR_SpeechToText.GetResponse();
if (HWR_Response.StatusCode == HttpStatusCode.OK)
{
StreamReader SR_Response = new StreamReader(HWR_Response.GetResponseStream());
Console.WriteLine(SR_Response.ReadToEnd());
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
Console.ReadLine();
}
}
}
