Recently contributed a patch to FluidAudio that sped up Parakeet V2 and V3 to 320x and 282x faster than real time, respectively:

That means one hour of audio transcribed in 11.25 and 12.75 seconds.

The Inscribe post doesn't give a speed factor for SpeechAnalyzer. However, this Argmax blog post reports 70:

Based on that, FluidAudio is ~4.6x and ~4.0x faster.
