should these be named as SPEECH_INPUT_RECORDING_STARTED (and similarly below) as
they are specifically about recording and not about the full session (i.e.
results available as well) ?

Fixed. Result availability is not required as these notifications are actually
dispatched to allow SpeechInputAsyncFunction to detect manager state machine
changes.
