I am trying to find the audio file that is played immediately after you manually start audio input via tapping the round microphone button on the search line of the Google Now application or saying "OK Google Now".

I find it kind of odd that the speech recognition extension for Chrome is still in its beta stage while the Android application is so polished but case in point, the sound file used for the extension is obnoxious. Not only is it three times as loud as every other desktop notification sound and genuinely painful to listen to with headphones but it plays every time you open a tab containing the google search engine. It'd be one thing if I could just drop the playback volume on Chrome through the audio control panel but I usually use Google Music for audio playback.

Anyway, I found the irritating mp3 reference in the code for the extension and I was hoping to copy and download the one used in Google Now from my phone to my laptop, move it to the Background.html folder and replace the reference with the mp3 that I want.

Either the location of the file within Android or the actual name of the audio file used would be great; if I can't find it through the file explorer, being able to find it online is just as good but so far I haven't had much luck.

  • You're probably having trouble finding it because the sound isn't part of Google Now, it's part of the voice recognition engine. – Dan Hulme Mar 5 '14 at 9:10
  • I realize that, I've checked just about every path that I can think of though. It isn't kept with the rest of the system sounds and since it is the same across multiple devices, it can't be in the framework or any of the carrier/manufacturer specific files groups. Since the sound works offline it can't be an HTML reference. If it is part of the voice recognition engine, what is the file location of it? – Austin Mar 5 '14 at 10:00
  • It could be inside the appropriate APK. – Dan Hulme Mar 5 '14 at 10:06

    I found what I suspect to be the right file (open.wav) through the path Velvet.apk/res/raw/open.wav the only problem is it doesn't seem to be your typical wave file. I extracted and decompressed the apk using a desktop utility but it is still unreadable. Any ideas? – Austin Mar 5 '14 at 10:48
