    copied!<p>I tried LatticeDemo.java. And, I could get the result as shown in the example result. This example is using "AudioFileDataSource" for voice data (10001-90210-01803.wav). I am trying to recognize this voice data in a different way using StreamDataSource.</p> <p>But, I get a different result. I would like to hear any idea.</p> <p>The following is the steps I took:</p> <ol> <li><p>get Byte data from 10001-90210-01803.wav by the following code</p> <pre><code>File f = new File(file); ByteArrayOutputStream out = new ByteArrayOutputStream(); BufferedInputStream in; try { in = new BufferedInputStream(new FileInputStream(f)); return ByteStreams.toByteArray(in); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } </code></pre></li> <li><p>Then, just put this byte data called "data" into ByteArrayInputStream like the following</p> <p>StreamDataSource dataSource = (StreamDataSource) cm.lookup("streamDataSource"); ByteArrayInputStream st = new ByteArrayInputStream(data); dataSource.setInputStream(st, "Main Stream");</p></li> </ol> <p>Actually, when we use "setInputStream" function, the second argument(i.e. "Main Stream") has special meaning? I cannot see why this argument is needed.</p> <p>The configuration for streamDataSource is the following:</p> <p>&lt;component name="streamDataSource" type="edu.cmu.sphinx.frontend.util.StreamDataSource"&gt; &lt;property name="sampleRate" value="16000" /&gt; &lt;property name="bigendianData" value="false" /&gt; &lt;/component&gt;</p> <p>The output is</p> <pre><code>Loading... 17:48:01.941 WARNING dictionary Missing word: &lt;unk&gt; 17:48:02.543 WARNING dictionary Missing word: &lt;unk&gt; &lt;s&gt; i. &lt;/s&gt; &lt;s&gt; i. &lt;sil&gt; &lt;/s&gt; &lt;s&gt; i. a. &lt;/s&gt; &lt;s&gt; i. a &lt;/s&gt; &lt;s&gt; i &lt;/s&gt; &lt;s&gt; i a &lt;/s&gt; &lt;s&gt; i &lt;sil&gt; &lt;/s&gt; &lt;s&gt; i a. &lt;/s&gt; &lt;s&gt; high a &lt;/s&gt; &lt;s&gt; i &lt;/s&gt; &lt;s&gt; a i &lt;/s&gt; &lt;s&gt; a i. &lt;/s&gt; &lt;s&gt; i i &lt;/s&gt; &lt;s&gt; i i. &lt;/s&gt; &lt;s&gt; i. &lt;/s&gt; &lt;s&gt; i. i. &lt;/s&gt; &lt;s&gt; high &lt;/s&gt; &lt;s&gt; higher &lt;/s&gt; &lt;s&gt; tight &lt;/s&gt; &lt;s&gt; right &lt;/s&gt; &lt;s&gt; wright &lt;/s&gt; I heard: i </code></pre> <p>Regards</p>
