Scripting Audio Conversations (part 2) - User Files Upload with Google SpeechToText and Python Dash

Hello Everyone! My name is Andrew Fung, in this video, I will be showing you how you can upload an audio conversation file and get the transcription of using Google’s Speech-To-Text API and display the script on the web using Python Dash. In this second part of the video, we will be focusing on allowing users to input multiple audio files and displaying the transcription results on the website.
