In this post we will create a Windows console app that integrates with Azure Cognitive Services Speech Service to convert to text what we are speaking.
In Visual Studio, create a new console app:
You will see:
Add Microsoft.CognitiveServices.Speech through NuGet:
Click on the Solution->Configuration Manager:
Change the platform to your current platform:
Add the code. This is based on this sample code here. For yourapikey, use the key created here. For the region, use your region such as westus.
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using Microsoft.CognitiveServices.Speech; namespace Carl.SpeechRecognitionHelloWorld { class Program { public static async Task RecognizeSpeechAsync() { var factory = SpeechFactory.FromSubscription(yourapikey, yourregion); using (var recognizer = factory.CreateSpeechRecognizer()) { Console.WriteLine("Say something..."); var result = await recognizer.RecognizeAsync(); if (result.RecognitionStatus != RecognitionStatus.Recognized) { Console.WriteLine($"Recognition status: {result.RecognitionStatus.ToString()}"); if (result.RecognitionStatus == RecognitionStatus.Canceled) Console.WriteLine($"There was an error, reason: {result.RecognitionFailureReason}"); else Console.WriteLine("No speech could be recognized.\n"); } else Console.WriteLine($"We recognized: {result.Text}"); } } static void Main() { RecognizeSpeechAsync().Wait(); Console.WriteLine("Please press a key to continue."); Console.ReadLine(); } } }
Press F5 to run the application. You will see “Say something”. After saying something, it will appear in text, i.e. below I said “Testing 123” and it converted it to text and displayed it on the screen:
Once we get a response from the Speech API, we can use this to look perform any number of actions.
In our next post we will use voice input to look up the weather.
I AM SPENDING MORE TIME THESE DAYS CREATING YOUTUBE VIDEOS TO HELP PEOPLE LEARN THE MICROSOFT POWER PLATFORM.
IF YOU WOULD LIKE TO SEE HOW I BUILD APPS, OR FIND SOMETHING USEFUL READING MY BLOG, I WOULD REALLY APPRECIATE YOU SUBSCRIBING TO MY YOUTUBE CHANNEL.
THANK YOU, AND LET'S KEEP LEARNING TOGETHER.

Hi Carl,
SpeechFactory is deprecated or not. Because I try your advice and SpeechFactory not exist.
If deprecated how I must customize your code?
Thanks in advance.
