Final answer:
The question asks about a persistent regional dialect feature in Ottawa Valley speech among young English speakers, but the detail isn't provided. Regional dialects are influenced by history, geography, and socio-cultural factors, and are often preserved by geographical isolation as seen in other dialects like Appalachian English.
Step-by-step explanation:
The specific regional dialect feature that is still clearly found in the speech of the youngest generation of English speakers in the Ottawa Valley today isn't explicitly mentioned in the provided information. However, it's important to understand that regional dialects are forms of a language specific to a particular region, influenced by various factors such as migration patterns, geographical isolation, and socio-cultural dynamics. For instance, the unique dialectical features found in Appalachian English, influenced by Scottish and Irish settlers, have been preserved due to the region's inaccessibility, leading to limited in-migration. Similarly, the speech of the Ottawa Valley could retain certain features if influenced by similar isolating factors. Linguists utilize tools such as dialect maps to analyze and represent these linguistic variations. Midland American English, perceived as more neutral, contrasts with regional dialects shaped by geography, such as mountain or coastal regions which tend to have more distinct linguistic features.
