![]() I’d encourage you to try speech recognition out on your own in your own apps. These topics are more advanced than this article allows, but if you need longer-running live audio transcription or need to make a “hands-free” voice triggered system, Azure cognitive services' speech API has you covered. These two methods allow us to transcribe a stream of audio with no definitive end (for continuous recognition) and listen for a pre-trained “wake word” similar to how most voice activated smartphone assistants work. Microsoft also gives us the StartContinuousRecognitionAsync and StartKeywordRecognitionAsync along with their associated Stop variants. Of course, there’s more we can do with speech to text. That’s all we have to do to get audio from the mic into a dotnet string! Other Workflows ![]() The operation was cancelled before it could completeĬonsole.WriteLine( "Speech Recognition canceled.")
