The terms voice and speech are sometimes confused. Here’s the distinction between the terms voice and speech:
“Voice” refers to sound produced in the human vocal tract.
“Speech” is the signal produced by modulating voice into meaningful patterns.
Other examples of terms that are often confused are “sound” and “audio.” Do you know the difference? And how about “tone” and “tonality?”
Another more important example is “Inclusive Design” vs. “Accessible Design.”
For me, Inclusive Design defines a methodology with a focus on the full range of human diversity. The aim is to make everyone feel welcome and included.
Accessible design has a narrower scope than inclusive design. It’s about giving people equal access.
