Adding Audio Output to an Alexa Skill

It’s pretty easy to add audio to an existing Alexa skill. The biggest trick is probably getting the audio converted into an Alexa-Friendly format. Here’s how I did this:

  1. Exported my audio from Adobe Premier (or whatever you’re using to build your audio files)
  2. Used ffmpeg to convert the audio to the right format:
    ffmpeg -i my.mp3 -ac 2 -codec:a libmp3lame -b:a 48k -ar 16000 my-converted.mp3
  3. Upload my new converted audio into an s3 bucket

Adding Audio to an Alexa Skill

Assuming you already have an existing skill, you can use this simple SSML to refer to your file:

<audio src="https://s3-us-west-2.amazonaws.com/yourbucketname/my_converted.mp3" />
