Speaking Thai
Thai is a tonal language belonging to the group of Ka-Tai languages, the five tones are monotone, low, falling, high, and rising. This can be a rather complicated language for the visitor; however, English is quite widely understood, particularly in Bangkok where it is almost the major commercial language.
