Guru to Go: a speech-controlled meditation assistant and sentiment tracker
Here, you see a Demo video of a voice-controlled meditation assistant that we worked on in the course “Conversational Agents and speech interfaces for learning” (Course Description)
The central goal of the entire project was to make the Assistant be entirely speech controlled, such that the phone needn’t be touched while immersing yourself in meditation.
The Chatbot was built in Google Dialogflow, a natural language understanding engine that can interpret free text input and identify entities and intents within it. We wrote a custom python backend to then use these evaluated intents and compute individualized responses.
The resulting application runs in Google Assistant and can adaptively deliver meditations, visualize sentiment history and comprehensively inform about meditation practices. Sadly, we used beta functionality from the older “Google Assistant” Framework, which got rebranded months after by Google into “Actions on Google” and changed core functionality requiring extensive migration that neither Aron, my partner in this project, nor I found time to do.
Nevertheless, the whole Chatbot functioned as a meditation player and was able to graph and store recorded sentiments over time for each user.
