Natural language processing
QUESTION: What are the useful things that can be done with using natural language processing?
Audacity is a free, open-source, cross-platform software for recording and editing sounds. It is available for both Windows, Mac, GNU/Linux, and other operating systems.
There are a number of tools you can use to record your podcast. The simplest might be Online Voice Recorder. However, you can also consider using Audacity. To record your podcast with Audacity consult the step-by-step Audacity Development Manual tutorial or choose another online voice recording tool. I recommend Audacity because it’s open-source and students won’t have to pay anything to use it.
