0 - default mode (no latency optimizations)
1 - normal latency optimizations (about 50% of possible latency improvement of option 3)
2 - strong latency optimizations (about 75% of possible latency improvement of option 3)
3 - max latency optimizations
4 - max latency optimizations, but also with text normalizer turned off for even more latency savings (best latency, but can mispronounce eg numbers and dates).
