• Google Speech API - Is there a way to determine if the audio has human voice or not ?

  20 décembre 2019, par stupid_sma

  I am making an audio filtering application at work that reads over hundreds of audio files and filters them. So, if the audio has human voice in it, it will accept it and if it does not- it will delete the audio file.

  I am using ffmpeg to get the details of the audio and add other filters like size and duration and silence (though it is not very accurate in detecting silence for all audio files.)

  My company asked me to try the Google Cloud Speech API to detect if the audio has any human voice in it.

  So with this code, some audio files return a Transcript of spoken words in the audio file, but what I need is to determine if a human is speaking or not.

  I have considered using hark.js for it but there does not seem to be enough documentation and I am short on time !

  Ps. I am an intern and I’m just starting out with programming. I apologize if my question does not make sense or sounds dumb.

• Auto install FFMPEG on Google Compute Engine (Debian Wheezy 7.8)

  1er octobre 2015, par DynamoBooster

  I have a Google Cloud Compute Engine project and want to auto-install FFMPEG on all the instances. I am using the node.js module https://github.com/fluent-ffmpeg/node-fluent-ffmpeg to watermark videos uploaded to the server and generate thumbnails. It’s working perfectly fine on my local machine that has ffmpeg installed. But how do I install/auto install ffmpeg on all virtual machine instances in the google cloud project ?
