Spanish is the most-widely spoken language in Ecuador, though great variations are present depending on several factors, the most important one being the geographical region where it is spoken. The three main regional variants are:
Other sociolinguistic factors that influence in the way of speaking are the ethnic or social class of the speaker, and whether the speaker lives in an urban or rural area. Since the Coast and the Highlands are the most populous areas, these are the country's most widely used dialects, despite being quite different from each other. For instance, there are many idioms specific to each region or province, and others that are used and understood nationwide.
This Spanish variant is classified within the Equatorial Spanish dialect, which extends from the south Pacific coastal Colombia to the northern coast of Peru, crossing the Ecuadorian seacoast. The influential linguistic center of this dialectal region is the port city of Guayaquil.
The most remarkable feature of this variant, is the aspiration of the letter "s" at the end of words or when preceded by another consonant, often being pronounced as a smooth English "h". Likewise, letter "j" is not pronounced as strongly as in other variants [x] but rather smoothly and aspirated [h]. These features are shared with the Caribbean and Canary Islands dialects of Spanish.
Thus, this dialect set the phonemical axis of accentual-tonal transition throughout the American varieties of Spanish, which extends geographically from the northern semi-low intonation of Central American and the Caribbean dialects (since only the European variants of Spanish are particularly low-pitched) to the sharp high intonation characteristic of the lands located south, typical of Peru, Chile and Argentina.
