I tried to include TensorFlow in the submission headline, but that would have been too long. "Show HN: State-of-the-Art German Speech Recognition in 284 lines of C++" uses up 72 of the 80 character limit. Originally I also wanted to mention that this is and offline, cloud-free, and privacy-respecting, but that, too, didn't fit.
I can appreciate your dilemma, but I think the submission would have been better served if the title emphasizes the real win, which is improved accuracy over some alternatives (like you mention elsewhere in the comment thread), rather than lines of code (because that invites scrutiny on the wrong, non-salient dimension).
