However, note that the app was still responsive enough overall. So essentially you get the same excellent speech recognition as seen on the desktop software – the only meaningful difference we noticed was a very slight delay in our spoken words appearing on the screen (doubtless due to processing in the cloud). Replace the contents of SpeechRecognition.Dragon Anywhere is the Nuance mobile product for Android and iOS devices, however this is no ‘lite’ app, but rather offers fully-formed dictation capabilities powered via the cloud. Install the Speech SDK in your new project with the NuGet package manager. You can use the Azure portal or Azure Command Line Interface (CLI) to remove the Speech resource you created.Ĭreate a new C++ console project in Visual Studio Community 2022 named SpeechRecognition. For more information, see How to use compressed input audio. For compressed audio files such as MP4, install GStreamer and use PullAudioInputStream or PushAudioInputStream.Using var audioConfig = AudioConfig.FromWavFileInput("YourAudioFile.wav") To recognize speech from an audio file, use FromWavFileInput instead of FromDefaultMicrophoneInput:.For information about continuous recognition for longer audio, including multi-lingual conversations, see How to recognize speech. This example uses the RecognizeOnceAsync operation to transcribe utterances of up to 30 seconds, or until silence is detected.Now that you've completed the quickstart, here are some additional considerations: RECOGNIZED: Text=I'm excited to try speech to text. What you speak should be output as text: Speak into your microphone. Speak into your microphone when prompted. If you don't set these variables, the sample will fail with an error message. Make sure that you set the SPEECH_KEY and SPEECH_REGION environment variables as described above. Run your new console application to start speech recognition from a microphone: dotnet run For details about how to identify one of multiple languages that might be spoken, see language identification. The default language is en-US if you don't specify a language. To change the speech recognition language, replace en-US with another supported language. OutputSpeechRecognitionResult(speechRecognitionResult) Var speechRecognitionResult = await speechRecognizer.RecognizeOnceAsync() Using var speechRecognizer = new SpeechRecognizer(speechConfig, audioConfig) Ĭonsole.WriteLine("Speak into your microphone.") Using var audioConfig = AudioConfig.FromDefaultMicrophoneInput() SpeechConfig.SpeechRecognitionLanguage = "en-US" Var speechConfig = SpeechConfig.FromSubscription(speechKey, speechRegion) Static void OutputSpeechRecognitionResult(SpeechRecognitionResult speechRecognitionResult)Ĭonsole.WriteLine($"RECOGNIZED: Text=") Ĭonsole.WriteLine($"CANCELED: Did you set the speech resource key and region values?") Static string speechRegion = Environment.GetEnvironmentVariable("SPEECH_REGION") Static string speechKey = Environment.GetEnvironmentVariable("SPEECH_KEY") This example requires environment variables named "SPEECH_KEY" and "SPEECH_REGION" Replace the contents of Program.cs with the following code. Install the Speech SDK in your new project with the. The Program.cs file should be created in the project directory. Open a command prompt where you want the new project, and create a console application with the. Recognize speech from a microphoneįollow these steps to create a new console application and install the Speech SDK. For example, westus.įor more configuration options, see the Xcode documentation. Set SPEECH_REGION to the region of your resource. To set the environment variable for your Speech resource region, follow the same steps. Enter SPEECH_KEY for the Name and enter your Speech resource key for the Value.Under Environment Variables select the plus (+) sign to add a new environment variable.Select Arguments on the Run (Debug Run) page.For example, follow these steps to set the environment variable in Xcode 13.4.1. Xcodeįor iOS and macOS development, you set the environment variables in Xcode. bash_profile, and add the environment variables: export SPEECH_KEY=your-keyĪfter you add the environment variables, run source ~/.bash_profile from your console window to make the changes effective. export SPEECH_KEY=your-keyĪfter you add the environment variables, run source ~/.bashrc from your console window to make the changes effective. For example, if you are using Visual Studio as your editor, restart Visual Studio before running the example. If you only need to access the environment variable in the current running console, you can set the environment variable with set instead of setx.Īfter you add the environment variables, you may need to restart any running programs that will need to read the environment variable, including the console window.
