Lectura directa, řápida i fázil del español (LDŘF), (Direct, Fast & Easy Reading of Spanish) is a software tool that converts texts in our language, Spanish, into a simplified, binuivocal spelling system, in which each sound corresponds to one, and only one, letter; thus facilitating understanding for new readers, (whether they are children who are native Spanish speakers or speakers of other languages who are learning Spanish). Any change that occurs is indicated in red, to illustrate that this letter corresponds to a different one in the normative system.

Our application consists of a text box where you can type or paste any text in normative writing, and, using the command, "CONVERT", to obtain a conversion to our direct reading system, quickly and easily.
In addition, we also offer the option of choosing between Northern Peninsular Spanish or Southern Peninsular and Latin American Spanish.
Furthermore, you have the option of writing all of the text in capital letters, which many pedagogical trends advise using to improve the process of learning to read.

Unlike many other languages, Spanish has a system of writing that we could categorize as “mathematical.” There are no exceptions, since every written expression corresponds to one, and only one reading interpretation, (except in the unique case of “w” which went from being pronounced as /b/ due to the influence of the German, to being pronounced as /gu/, due to the influence of the English.) This fact is an undeniable advantage in the learning and practice of reading and writing, since there is no ambiguity and we know in advance how a word should be read, without having prior knowledge of reading it.

However, that is not to say that the system of writing is simple or completely biunivocal, (that each sound corresponds to one, and only one letter), which would be ideal for easy and effective learning.

In our writing, there are five circumstances that prevent biuniqueness:

• Sounds represented by two letters (including three:/k/ (c,qu,k): /b/ (b, v); /g/ (g, gu); /i/ (i, y)...
• Letters that represent two sounds: c (/k/, /z/); r (/ř/, /r/)...
• Double letters that represent only one sound: ch (/č/); rr (/ř/)...
• A single letter that represents two sounds: x (/ks/).
• A letter that is silent: h.

Perhaps it would be logical in the current historical and linguistic context, to make biunivocal changes to the Spanish spelling that exceeded the circumstances that we have just described, to facilitate literary acquisition, and with it, the dissemination of our language. But this is beyond our reach. Therefore, in order to simplify the learning and practice of reading, we offer this simple computer application that allows us a biunivocal reading, which, also safeguards the current spelling, by marking in red all of the changes that we have inserted in the text and which indicate to us, in the normative writing system, that they are written in a different way. It will suffice to have the equivalency table on hand to determine how something is written with the official spelling.

Here we point out the changes that occur with our LDŘF system:

NORMATIVE SPELLING	➝	OUR SPELLING
(a e i o u)h!	➝	(a e i o u)!
c followed by e,i	➝	z
ch	➝	č
g followed by e,i	➝	j
gu followed by e,i	➝	g
h(a e i o u)	➝	(a e i o u)
k	➝	c
ll	➝	y
qu	➝	c
r at the beginning of a word or after a consonant l, n o s	➝	ř
rr	➝	ř
ü	➝	u
v	➝	b
w	➝	gu (except in wagon-lit, Wagner and wagneriano, Wenceslao, Wolframio, Kuwait and Holiwood that is pronounced with a b).
y at the end of a word	➝	i
x	➝	cs o s (if it is at the beginning of a word)
On the other hand, at the phonological level, Spanish contains a subtle difference between what we can call the Northern Peninsular variety (from the central and northern Iberian Peninsula) and the Southern Peninsular and Latin American variety (southern Iberian Peninsula, the Canary Islands and Latin America). It differentiates between the (Northern Peninsular) and the (Southern Peninsular and Latin American varieties with the distinction between the sibilant /s / y / z/. In the case of Southern Peninsular and Latin American Spanish, only the archiphoneme /S/ is used. For this reason, in our application, we offer two versions: Northern Peninsular Spanish and Southern Peninsular and Latin American Spanish. This sole difference is reflected in the Southern Peninsular and Latin American Spanish version with a distinguishing command:
c, followed by e,i	➝	s (instead of z)
z	➝	s

In addition, there are many literacy experts who defend the use of exclusively capital letters during the early stages of learning. This is due to their being more easily identified because there are no graphic varieties, since all of the letters are the same size and they are not connected, (which could hinder their interpretation). Consequently, we have also included a command that allows for all of the text to be typed in capital letters.

Ultimately, we believe that our Lectura directa, řápida i fázil (fásil in the Latin American version) (LDŘF) (Direct, Fast & Easy Reading of Spanish) is a useful and effective tool to help both children and adults, native speakers and foreigners, to begin to learn and develop a command of our language.
