📱 Meeting Maker (Detailed Guide)
-
Client A client is developed with Jetpack Compose. It is a basic app that allows users to record their meetings and upload them to a server. Ktor is used for uploading the recording to the server.
-
Server A server is developed with Python. It is a basic server that allows users to upload their recording(mp3 files) and process them into well organized meeting notes using FastAPI and whisper-large-v3-groq model. In the future, it will be enhanced to generate action items from the meeting notes.
📱 Child Care (Detailed Guide)
- Child Care is a mobile app that is developed in flutter. It is a app which used a child cryping voice and it predict what are the reason of child cry. It uses librosa library to extract features from the audio and then uses a pre-traineed llama-3.3-70b-versatile model to predict the reason of child cry.
- Server A server is developed with Python. It is a basic server that allows users to upload their recording(mp3 files) and process them into well organized meeting notes using FastAPI and whisper-large-v3-groq model.
