Speech recognition, text analysis and emotion detection using Azure Cognitive Services

This JavaScript-based demo webapp for an article in c't Magazin 18/2017 enables you to transcribe spoken text, fix spelling errors, detect keywords, analyze the emotion of the text and the expression of your face. It uses several Cognitive Services of Microsoft Azure:

• Bing Speech API
• Bing Spellcheck API
• Text Analytics API
• Emotion API

The app comes in two flavours: without-proxy includes the keys in the source code, with-proxy passes requests to 3 of the 4 APIs through a simple PHP proxy which is in the proxy directory. The speech recognition key is used with WebSockets and is only minimally protected by some bit moving mojo. Both flavours of the app are functionally identical.

Live Demo: woerter.de. The live demo does not contain the spellchecker and has limited API quota.
