Obtaining Encoder Features

[magacc1]

I'm looking to use some of the pretrained speech recognizers and compute their encoder output features in real-time.

When I'm looking at the API of _Recognizer / _sherpa_onnx.OnlineRecognizer as defined here

I see only the following methods, and cannot find a way to get access to specifically compute the encoder outputs:
'create_stream',
'decode_stream',
'decode_streams',
'get_result',
'is_endpoint',
'is_ready',
'reset'

Can anyone help provide pointers on how to get the encoder features, or find the code underneath decode_stream and break it down to compute the encoder results?

Thanks!

We don't provide such an API as general users don't need it.

For the online transducers, you can take a look at

sherpa-onnx/sherpa-onnx/csrc/online-recognizer-transducer-impl.h

Lines 224 to 225 in 8af2af8

	auto pair = model_->RunEncoder(std::move(x), std::move(states),
	std::move(x_copy));
