Coarticulation — where sounds of successive letters blend together in natural speech — is a major factor making speech recognition difficult
Summary
In natural speech, the shape of one sound bleeds into the next, so a recognition system can't simply listen for clean, textbook pronunciations of each letter in isolation. This blending is a core reason why turning spoken language into text is fundamentally harder than it looks, because the raw audio signal doesn't line up neatly with the discrete units the system is trying to identify.
