Almost every Central and South American country and island nations in the Atlantic speak Spanish. Besides Spain, there are a few other countries besides these where Spanish is a second or third language spoken by citizens. Despite the number of countries where Spanish is spoken, the dialects, cultures, and slang are wildly different. It is almost as difficult to fully learn and understand as an Asian language is. That said, you may either want to learn some Spanish or use one of the following Spanish interpreters or translators:
Spoken Translation on Mobile Devices
The closest the human race has come to the universal communicators from programs like Star Trek are the spoken translation apps in mobile devices. Simply download a translation app, or use the built-in one on your smartphone, speak what you want to say in another language, and the phone translates it into the native language of the person you are trying to speak to. Additionally, the other person can speak in his/her native language, and the phone or phone app translates it back to you.
Written or typed Spanish on a computer is quickly translated. Companies such as Google and Facebook now offer a prompt on-screen that asks you if you would like the writing translated. If you click on it, or click on "yes," the translation is automatic and you can read what the native Spanish speaker has written. There are also lots of free language translator websites online that you can use to translate the written/typed words.
There are special devices that you can connect to your phone line which not only translates Spanish into English but also screens the Spanish being spoken for key words that signal what country the speaker is from. Slang in Mexican Spanish is very different from the slang in Honduras, Puerto Rico, Argentina, Chile, or Spain. Usually, this device is used by the police or investigative teams trying to locate where the speaker is from and where the speaker might be now.
Human Spanish Translator
If you need an expert Spanish translator who knows several dialects from several Spanish-speaking countries, then you should hire a human Spanish translator. Most translators charge by the hour or the day. This option is actually the best since you can learn a lot about the culture and slang of the country from the person with which you are trying to communicate.
Contact a local Spanish interpreter for more information and assistance.
