compulim/web-speech-cognitive-services
Polyfill Web Speech API with Cognitive Services for both speech-to-text and text-to-speech service.
Implements a ponyfill pattern that wraps Azure Cognitive Services Speech SDK to provide W3C-compliant SpeechRecognition and SpeechSynthesis APIs without polluting the global namespace. Supports flexible credential management (subscription keys, authorization tokens, or custom hostnames) and integrates with Web Audio API for synthesis playback, requiring WebRTC for recognition on HTTPS or localhost. Available as both UMD bundle and NPM package, with optional AudioContext priming for Safari compatibility.
