Thanks! They're not well known outside speech circles. Zipformer is an encoder architecture from the k2 / icefall team (the next-generation Kaldi project), made for fast streaming speech recognition: https://arxiv.org/abs/2310.11230 Banafo is a small company that trained Kroko, a streaming Zipformer2 transducer, and released community models on Hugging Face: https://huggingface.co/Banafo/Kroko-ASR I picked a transducer because it suits a microcontroller. The encoder is 98% of the weights, and it runs once per 1.28 s chunk of audio, so each weight is read from PSRAM once and reused for every…
