Here’s an example: a market research company is holding a 10-person focus group with folks who do speak English but aren’t native speakers. The group is comprised of teenagers from the rural south. So that’s 10 people, many talking over each other at certain points, who don’t speak English well, use regional dialect, and also use many newly-created words. That’s hard enough for a human to transcribe. But for machines, at this time, it’s not possible to achieve anywhere near 100% accuracy.
In the future, this will likely be solved in some technical way that my non-scientific brain cannot fathom. When it does, Atomic Scribe will evolve, just as language does. For now, it’s best to use human-powered services if you’re looking for accuracy. The rise of the machines will have to wait just a little bit longer.
