General
El texto era antiguo entonces se verificó con hablantes de Norogachi que revisaran si había léxico diferente, etc.
Si se trabaja con personas de otras comunidades tienen que normalizar los datos, es decir adaptarlos a las variaciones dialectales de la otra comunidad. Hubo una hablante de Cusarare, Guachochi que está considerado de la misma lengua y tenía dudas sobre algunas palabras.
