Description
Related to #3974.
Feature Request
In packages/bundle/src/speech/createMicrophoneAudioConfigAndAudioContext.ts, we are using PcmRecorder from Speech SDK:
- It is not using audio worklet via blob URL
- It is hardcoded to 16-bit mono 16 kHz, not dynamic according to the microphone input

Research direction
Start in packages/bundle/src/speech/createMicrophoneAudioConfigAndAudioContext.ts and inspect how Speech SDK's PcmRecorder is used. The work is complete when the project has its own recorder using an audio worklet via a blob URL and adapts to the microphone input instead of assuming 16-bit mono 16 kHz audio.
