Speech to text lab with Raspberry Pi

[jimbobbennett]

The cart contains a Raspberry Pi, along with a USB speakerphone containing a microphone and speaker.

One of the labs we need to use this is speech to text based off the Azure cognitive services speech service, all coded in Python.

There isn't a Speech SDK in Python for the Raspberry Pi at the moment, so this lab should use the REST API.

Hardware

• Raspberry Pi 4
• M0 USB speakerphone

Lab parts

This lab should focus on the Speech to Text scenario, with output to the console. As this lab needs to explain all the steps it needs to be documented either as markdown, or a Jupyter notebook that can be run on the Pi.

The lab should have a structure something like:

• Setting up the Pi (ideally with links to existing content such as the Microsoft RPI resources
• Setting up Jupyter Notebooks (if needed) - this can link to the existing documentation on this in this repo
• Setting up the Cognitive Service - ideally using a link to the relevant documentation in Microsoft Docs
• Recognizing speech and outputting the text

All labs should follow the lab contribution guidelines.
