<b>wchess : voice-controlled chess using Whisper + WebAssembly</b>
|
|
|
|
<br><br>
|
|
|
|
This is a demonstration of using Whisper to recognize voice commands in the browser.
|
|
|
|
<br><br>
|
|
|
|
Usage:<br>
|
|
|
|
<ul>
|
|
<li>Select a Whisper model</li>
|
|
<li>Accept the microphone permission request if prompted</li>
|
|
<li>Hold the button and say a chess move (e.g. "Knight to c3")</li>
|
|
<li>Release the button and wait for the move to be recognized</li>
|
|
<li>Repeat</li>
|
|
</ul>
|
|
|
|
Examples:<br>
|
|
|
|
<ul>
|
|
<li><b>"d4"</b></li>
|
|
<li><b>"e2 e4"</b></li>
|
|
<li><b>"Knight f3"</b></li>
|
|
<li><b>"Bishop to b5"</b></li>
|
|
</ul>
|
|
|
|
Features:<br>
|
|
|
|
<ul>
|
|
<li>Model quantization for reduced memory footprint (~42MB)</li>
|
|
<li><a href="https://github.com/ggerganov/whisper.cpp/pull/1229">Grammar-based sampling</a> for improved recognition accuracy</li>
|
|
</ul>
|
|
|
|
<b>
|
|
Note that not all chess moves are supported. For example, castling and pawn promotion
|
|
currently do not work, but can be easily implemented. There could also be some bugs in
|
|
the move handling logic in general. The main reason for that is to keep the implementation
|
|
simple. The assumption is that a real application would already have a proper move
|
|
validation logic in place.<br><br>
|
|
|
|
The main purpose of this example is to demonstrate the capabilities of whisper.cpp and
|
|
its application in the browser for voice recognition locally on your device.
