Could you build this?

No Writing a streaming speech recognition engine from scratch with custom feature extractors, CTC prefix-beam search, transducer decoders, and latency accounting requires advanced digital signal processing and speech modeling expertise.

What it would actually take: Requires low-level DSP for streaming STFT and log-mel filterbank extraction, custom C++/Cython or highly vectorized NumPy/PyTorch implementations of CTC prefix-beam search and RNN-T alignment, plus forced alignment algorithms. The hard part is managing real-time chunked streaming state, latency accounting, and beam-search pruning efficiency without high runtime overhead. This requires graduate-level speech recognition and digital signal processing engineering knowledge.
