This tutorial demonstrates how to programmatically create a subtitle track using AssemblyAI's Speech-to-Text API and add it to a Mux video. The process involves uploading an mp4 file to Amazon S3, transcribing the video with AssemblyAI's automatic transcription service, downloading the subtitle files, and uploading them to S3. Finally, the video is uploaded to Mux using their video API along with the subtitle text track. The tutorial provides detailed steps and code snippets for each part of the process.

This tutorial demonstrates how to use Python's PyAudio and websockets libraries along with AssemblyAI's real-time transcription feature to transcribe audio from a microphone in real time. The process involves installing the required libraries, setting up an API key from AssemblyAI, creating a stream using PyAudio, making an asynchronous function for sending and receiving data, and running the code in a loop. The final result is a program that transcribes audio from the microphone to text in real time.

This guide explains how to programmatically use Twilio's voicemail feature with Python. It covers setting up a custom webhook using Flask and ngrok, updating the phone number's webhook to your custom one, downloading Twilio voicemail recordings, and deleting a Twilio phone number. The tutorial also provides code snippets for each step.

In this tutorial, learn how to create a burner phone using Python with Twilio and transcribe incoming calls using AssemblyAI's API. The process involves provisioning a number from Twilio, creating a Flask endpoint to record voice, updating the webhook endpoint for the number, making example calls, downloading .mp3 files, transcribing them via AssemblyAI, comparing transcription accuracy between Twilio and AssemblyAI, and finally deleting the phone number.
