Uncover the science behind the transformation of sounds into speech — speech Speech is the faculty of producing articulated sounds, which, when blended together, form language.

Distinguishing between a dialect and a separate language is often complex, as the boundary between them is not absolute and can be somewhat arbitrary.12

Typically, the primary criterion used is mutual intelligibility: dialects of the same language are generally considered to be mutually intelligible, meaning speakers can understand one another despite differences in grammar or vocabulary. In contrast, different languages are generally not mutually intelligible without specific learning. However, this criterion is relative, as intelligibility is rarely complete between dialects and may still exist to some extent between closely related languages.12

Sociopolitical factors also play a significant role in this distinction. Linguistic varieties that are viewed as dialects in one historical or political context may be reclassified as distinct languages in another, often reflecting shifts in national or local identity. Because of these social and historical influences, there is no precise, universally applicable limit that separates a dialect from a language; rather, they exist on a scale of communication.12
