Export to ncnn
==============
We support exporting the following models
to `ncnn <https://github.com/tencent/ncnn>`_:
- `Zipformer transducer models <https://github.com/k2-fsa/icefall/tree/master/egs/librispeech/ASR/pruned_transducer_stateless7_streaming>`_
- `LSTM transducer models <https://github.com/k2-fsa/icefall/tree/master/egs/librispeech/ASR/lstm_transducer_stateless2>`_
- `ConvEmformer transducer models <https://github.com/k2-fsa/icefall/tree/master/egs/librispeech/ASR/conv_emformer_transducer_stateless2>`_
We also provide `sherpa-ncnn`_
for performing speech recognition using `ncnn`_ with exported models.
It has been tested on the following platforms:
- Linux
- macOS
- Windows
- ``Android``
- ``iOS``
- ``Raspberry Pi``
- `爱芯派 <https://wiki.sipeed.com/hardware/zh/>`_ (`MAIX-III AXera-Pi <https://wiki.sipeed.com/hardware/en/maixIII/ax-pi/axpi.html>`_).
- `RV1126 <https://www.rock-chips.com/a/en/products/RV11_Series/2020/0427/1076.html>`_
`sherpa-ncnn`_ is self-contained and can be statically linked to produce
a binary containing everything needed. Please refer
to its documentation for details:
