This is a sample application that uses Azure real-time speech recognition service.Azure key is stored only on the server side. Client token for using the service is issued from Azure server by Consume REST API with the key on the server side.Client uses Azure Speech SDK from CDN.The implementation of JavaScript for using the SDK is really simple.
Please note that this sample application can only be used as PWA or on a browser.It seems that the WebView of the native-built app doesn't fully support the Web API's media handling features. The Speech Service JavaScript SDK used in this component is based on the Web API.
