Language Differences[]

Phonetically speaking, English and Spanish are similar enough to allow for conversions between them to be understandable. Despite the fact that English has 20 vowel sounds and Spanish only 5, the spanish vowels can be used as approximates for the english ones with a varying degree of closeness (Ex: "a" in spanish can be used for "@", "V", etc.).

Accent is a large issue in creating understandable English from Spanish. One main issue is the accentation of "r" and "x". Due to Spanish having a trilled "r", the untrilled "r" obtains an amount of trill. Another example, with a larger and more noticable difference, is the Spanish "x" phoneme being used in place of the English "h" phoneme. The "x" phoneme becomes harsher than "h" and slightly trilled, causing it to be closer to the German sound used for "ch". This can be alleviated partially by adding "_0" to "x" creating "x_0". The "_0" removes some of the harshness creating a closer approxomation, however, further editing is required to create a closer approxomate.

Spanish to English[]



As opposed to english voicebanks where the dipthongs are included as seperate phonetics, spanish voicebanks have the dipthongs formed from a combination of two vowels.(Ex: "aI" as opposed to "a I")
