In NuGet, add the “” package.Īdd the following code to your console app, changing lines 13, 53 and 55 and run the program. Also note the region, you will need these for your program. table file where the application can access it.įinally at the top right, click the gear icon and select “speech resources” and click the show key icon to get the speech key. Select the pronunciations you desire and click Train.Īfter training is complete (it does take a while), download the keyword file for your program. ![]() Name you model and add your Keyword phrase and click Next. To start, Log into the Azure Speech Portal: and select Custom Keyword.Ĭreate a new Project and Click Train Model. You can use anything, just make sure it is unique as you don’t want the program falsely interacting. Without this, you would have to continually stream audio to the cloud just to determine if the user is trying to interact with the system.īeing a Marvel fan, I decided my Key Word would be “Hello Jarvis”. Key Word Spotting at the edge is critical for this, as it does not incur bandwidth or have a dependency on latency. This post only focuses on the first two steps, KWS and Speech to Text - both part of the Azure Speech Service. Consider the following diagram that shows the interaction. From that point, we can leverage Speech to Text and LUIS to take real action. With a recent addition of “Key Word Spotting” (KWS) in the Azure Speech Service, the process is really quite simple, as shown below.īefore getting started, understand that KWS, is just the entry point. RecognizedSpeech)Ĭonsole.For fun, I wanted to write my own “virtual assistant” and not use an Echo Dot or the like. For long-running multi-utterance recognition, use StartContinuousRecognitionAsync() instead. ![]() shot recognition like command or query. Note: Since RecognizeOnceAsync() returns only a single utterance, it is suitable only for single The task returns the recognition text as result. single utterance is determined by listening for silence at the end or until a maximum of 15 Starts speech recognition, and returns after a single utterance is recognized. Using ( var recognizer = new SpeechRecognizer( config))Ĭonsole. Creates a speech recognizer using microphone as audio input. FromSubscription( "YourSubscriptionKey ", "YourServiceRegion ") Replace with your own subscription key and service region (e.g., "westus"). Creates an instance of a speech config with specified subscription key and service region.
