Google Speech API v1beta1 very slow?
<p>I was super excited when learning that Google has finally released its official speech API for developers. I have always been amazed by how great Google's speech recognition works in Android, Chrome, and other products.</p>

<p>I created a Google Cloud account, enabled the speech API, and created a few testing scripts following the <a href="https://cloud.google.com/speech/docs/" rel="nofollow">Google Speech API documentation</a>. The accuracy is super high, but the speed is insanely slow. An 18-second audio file would take their engine around 16 seconds to transcribe! Microsoft Bing Speech API only needs 3-4 seconds to do it!</p>

<p>Has anyone experienced the same? Or is it a problem of my configurations? Any help is highly appreciated!</p>

<p>Here is the code I used:</p>

<p>BASH:</p>

<pre><code>time curl "https://speech.googleapis.com/v1beta1/speech:syncrecognize?key={MY_API_KEY}" --header "Content-Type: application/json" --data '{"config":{"encoding":"FLAC","sample_rate":16000,"language_code":"en-US"},"audio":{"uri":"gs://accobot-speech/new_record.flac"}}'
</code></pre>
