My Experience at Hack The North 2020++

What is Hack The North anyways?

What is

How did we do it?

  1. IBM Watson: We used the tone analyzer API offered by IBM Watson to figure out the emotion in the user’s verbal journal entry. This works using a neural network trained to recognize tone in text on the IBM Cloud.
  2. VoiceFlow: VoiceFlow is a software that makes designing voice-enabled applications super easy. The key features we used were the API block, the logic tools, custom JavaScript (JS) and the integrated Google Sheets API. We used the API block to send IBM Watson the message that the user speaks and retrieve a response. We wrote some JS to a) correctly format the user’s speech so that it could be easily understood by the Watson API and b) to parse the .json file returned and extract the relevant data. The integrated Google Sheets API allowed us to have a database where we stored the relevant data from each API call. The logic units were used to check if the last three entries were negative emotions, and if so it would randomly suggest a mood-boosting activity.

Key takeaways:

  • Can’t wait for the next Hack The North!
  • Making a voice app doesn’t have to be hard.
  • I gained a lot of experience working with APIs.
  • Demoing our LIVE app to the judges was the most satisfying part of the whole experience!
  • If you’d like to try out for yourself, shoot me an email @ and I will add you to our alpha tester list!
