That's too strong. For instance, multi-person and high-noise environments will still have room for improvement. Unpopular languages will lag behind in development. I'd consider "solved' to mean that the speech-processing element of a Babelfish-like vocal translator would work seamlessly across many many languages and virtually all environments.
I'd say it will be just below the level of a trained stenographer with something like 80% probability, and "solved" (somewhat above that level in many different languages) with 30% probability.
With 98% probability it will be good enough that your phone won't make you repeat yourself 3 times for a simple damn request for directions.
Instead of prognosticating on AGI/Strong AI/Singularities, I'd like to discuss more concrete advancements to expect in the near-term in AI. I invite those who have an interest in AI to discuss predictions or interesting trends they've observed.
This discussion should be useful for anyone looking to research or work in companies involved in AI, and might guide longer-term predictions.
With that, here are my predictions for the next 5-10 years in AI. This is mostly straightforward extrapolation, so it won't excite those who know about these areas but may interest those who don't:
