With speech the main problem (I have felt) is that mistskes are difficult to correct.
I haven't yet seen an input system which would combine speech with touch in nice way.

Text selection on phones usually sucks, but that's only because you need to disambiguate between clicks and highlighting; if you had a dedicated screen that assumes a user wants to highlight a section it should be a lot more responsive.
I found speech recognition to be useful mostly for brain dumps. I've found I tend to think best when explaining or talking. I used to bring along a voice recorder on long drives, capture what I was thinking, then run it through voice recognition later. It was often a garbled mess, but usefully captured a lot of thinking. Modern recognition systems would do a lot better. Yeah, I should try that again.
Probably you could build some neat solution around this. Like a speakerphone style device with array of microphones to make it easier to identify who is speaking and pick up the words. Or maybe a regular smartphone is enough. The device/app would then just transcript what is spoken and annotate it with names.
Compared to audio recording the benefit would be that going through the written raw stuff is much faster and if you were present, then you can probably recall the stuff even if the transcription is not perfect. Also it might be more socially acceptable to use this solution that to record the meetings.
