How do speech-to-text tools work?

Though the specifics vary across different speech-to-text tools, they all follow the same general process:

  1. The sound waves generated from a voice are recorded using a microphone and converted into digital signals a computer can understand.
  2. These digital signals are processed to remove any unwanted noise and matched with phonemes (units of sound in language).
  3. These phonemes are analyzed and combined, often using artificial intelligence, to build corresponding words and sentences.
  4. These words and sentences are then stored as text.

If you’d like to see this process in action, try QuillBot’s free speech-to-text converter.

It’s called an online QR code because you need an internet connection for it to work. Some QR code content—such as Wi-Fi login details—needs to be available offline, so it must be stored in a “static QR code,” where all the information is directly contained in the code itself.

What’s the difference between editing and adding text in a PDF?

Editing a PDF involves changing the actual text of the document, whereas adding text is more like annotating. Editing is difficult and in many cases not worth it—it is better to go back to the course document and amend it before creating a new PDF.

Adding text to a PDF is simple with an online tool like the QuillBot PDF editor. As well as text, you can add images, highlighting, and drawings.
