<h1> APKs for two-pass speech recognition </h1>
This page lists the <strong>two-pass speech recognition</strong> APKs for <a href="http://github.com/k2-fsa/sherpa-onnx">sherpa-onnx</a>,
one of the deployment frameworks of <a href="https://github.com/k2-fsa">the Next-gen Kaldi project</a>.
<br/>
The name of an APK has the following rule:
<ul>
<li> sherpa-onnx-{version}-{arch}-asr-{lang}-{model}.apk
</ul>
where
<ul>
<li> version: It specifies the current version, e.g., 1.9.23
<li> arch: The architecture targeted by this APK, e.g., arm64-v8a, armeabi-v7a, x86_64, x86
<li> lang: The lang of the model used in the APK, e.g., en for English, zh for Chinese
<li> model: The name of the model used in the APK
</ul>
<br/>
<span style="color:red;">Two-pass:</span> Two models are used during the recognition. A streaming model
is used in the first pass, while a non-streaming model is used in the second pass. The purpose
of the first pass is to give feedback to users that the system is working and it displays results while
users are speaking. When an endpoint is detected, the samples between two endpoints are sent to the second
pass model for recognition. The output of the second pass model is the final recognition result.
<br/>
<br/>
<span style="color:red;">Features of the first-pass model:</span>
<ul>
<li> A streaming model
<li> Low latency
<li> Small in model size
<li> Runs very fast
<li> Low accuracy
</ul>
<br/>
<span style="color:red;">Features of the second-pass model:</span>
<ul>
<li> A non-streaming model
<li> High latency
<li> Large in model size
<li> Runs a bit slow
<li> High accuracy
</ul>
<br/>
<br/>
You can download all supported models from
