Source description

medocr-asr-bn — on-device Bangla ASR (ONNX) for the MedOCR pharmacy app

INT8 (MatMul-only dynamic quantization) ONNX export of the encoder of ai4bharat/indicconformer_stt_bn_hybrid_ctc_rnnt_large (MIT license, AI4Bharat), plus its CTC head, vocabulary, and mel filterbank. MatMul-only quantization is used because onnxruntime-android has no ConvInteger kernel.

Used by the MedOCR Android app for offline voice stocking (the pharmacist speaks price / expiry / quantity). The app downloads asr_encoder_bn.onnx once on first use; the small files ship inside the APK.

asr_ctc_bn.onnx	11559655

Contract: encoder audio_signal [1,80,T] float32 + length [1] int64 → [1,512,T']; ctc → logprobs [1,T',5633]; aggregate SentencePiece vocab, blank id 5632; 16 kHz mono input.
