Description

Support selectable audio input device. From user report, even AirPod is connected, on iOS, it is not selected as default. JavaScript is required to select the device and make it default.

Also, today, we have 3 references of microsoft-cognitiveservices-speech-sdk, which take up significantly amount of size in our bundle (~300 KB each). We are going to converge them into a single copy inside the bundle.

We will temporarily bump to a preview build of web-speech-cognitive-services. When we do production release, we will build a production version of web-speech-cognitive-services and bump the version in Web Chat.

Specific Changes

• Update webpack.config.js to reference to the same microsoft-cognitiveservices-speech-sdk package to reduce footprint by ~600 KB
• Add audioContext option to createCognitiveServicesSpeechServicesPonyfillFactory()
  • This is for speech synthesis and supporting our test infrastructure, we will send in a mock audioContext object
• Add audioInputDeviceId option to createCognitiveServicesSpeechServicesPonyfillFactory()
  • If no audioConfig is set, we will use audioInputDeviceId to select the correct audio input device
• Add samples to show how to select audio input device, and a comprehensive sample to try out this feature
• Update HTML test infrastructure to enable testing under IE11
  • Some packages are not transpiled to ES5. We added a postinstall script to transpile them after npm run bootstrap or lerna add. We prefer to use postinstall because build time is substantial and to reduce the tax on our build
  • These packages were not transpiled to ES5:
    • @babel/plugin-proposal-async-generation-functions
      • This package is mainly used under Node.js, hardly in a browser, and rarely on IE11
    • event-iterator
      • This package is using async iterator, which is not natively supported on IE11
    • microsoft-cognitiveservices-speech-sdk
• Bump react-say to not breaking IE11
