To say that someone speaks Engpsh with a "foreign accent" or "foreign intonation" means that they pronounce Engpsh words or phrases in a way that is characteristic of a different language or region. For example, if someone speaks Engpsh with a French accent, they might pronounce certain sounds or syllables differently than a native Engpsh speaker, or they might have a distinct intonation pattern that is typical of French speech.
It is important to note that having a foreign accent in a language does not necessarily mean that someone is not proficient in that language. Many people learn a second or third language as adults and may retain some elements of their first language's pronunciation or intonation, even after becoming proficient in the new language.
