Animales

A highly qualified team of experts in the Spanish language translated the Animals articles into Spanish for Animales. Trusted Translations, an authority in Spanish translation services, has worked extensively to find the best in Spanish-language translators. The Animales translations were triple-verified: first by a translator, then an editor, and then finally, after audio-recording, the audio was reviewed for pronunciation and quality. All articles were translated contextually. This is important because, for example, in Spanish, animal terms can vary depending on the animal’s gender and age, whereas in English, the same term is used. All of the audio in Animales was recorded by professional voice over artists who are native Spanish speakers.
