Do you have a source for that information I can research?
Alas, all of my research is from decades ago, which are now long lost, though I haven't noticed (on my own observations) that much, if anything, has changed. The few that I've tried aren't any better than those decades old, and few of the 'old guard', like Dragon Naturally Speaking, haven't had any substantial increases in a long time either.
Again, they all adapt to the latest changes in OS additions, but no one wants to rewrite their base coding, as they already have all the customers they expect to get. :( Essentially, it's a stagnant industry. The little research being done is in listening (mostly to casual comments about products those listening can then market to them), rather than making the underlying products any better.
On a side note, the products which I had almost 30 years ago (with a now defunct computer company) were vastly suprerior to what's available now. Back then, we had tools to rapidly craft tools to parse and decode language, whereas now, if it's done at all, you've got to code everything yourself from the ground up.
In my day, I could slap together a new language translator in a matter of days, now ...
Without the backing of an industrial base, and with no apparent sign of huge, hungry market, no one's investing anything at all into the industry (which I guess also includes me, since I actually know better).
Still, what tools are still available are all roughly equivalent. You'll need to speak fairly slowly and clearly, you need to say punctuation in order to enter it (ex: "This is a full stop, period."), and you'll need to waste quite a bit of time editing the garbage that results. It still works, it's just not any better than what we struggled with years ago, and does add to your editing time (think 'pre-edit' edits).
