No. The Indo-Guyanese (descendants of Indian indentured laborers, 1838–1917) speak English—specifically Guyanese Creole (Creolese) as vernacular and Standard English officially.
Guyanese Creole: English-lexicon creole with West African, Indian (Bhojpuri, Awadhi), Dutch, Portuguese substrates. "Mi de go" = "I am going." Mutually intelligible with effort for English speakers.
Heritage languages: Some elders retain Bhojpuri/Hindi phrases (religious, familial). Hindi taught in some schools; Indian Cultural Centre offers classes. But daily language = Creole/English.
Spanish? Only as foreign language (school, Venezuelan migrants, Brazilian border trade). Not community language.
