When babies open their mouths, they're not just spewing gibberish. They're actually talking in a highly advanced, adult-proof cipher...

The Baby-talk Cipher

When a baby talks, it could look something like gogooa gagooook aagaaoooy Each single-space separated section represents a character (so the example above represents 3 characters).

To decipher a section, we must count number of As and Os it contains. However, we only count those which are adjacent to another vowel. For example, the A in 'gag' would not count, but both the A and O in 'gaog' would.

Counting the example above would look like this:

Section    | Num Os | Num As

gogooa     | 2      | 1
gagooook   | 4      | 0
aagaaoooy  | 3      | 4

We then use these values to convert the input into plaintext on a Polybius square. This is a 5x5 representation of the English alphabet, omitting 'J' (please note that, in baby-talk, 0-counting rules apply to the table):

  0 1 2 3 4
0 A B C D E
1 F G H I K
2 L M N O P
3 Q R S T U
4 V W X Y Z

Using the number of Os as the column, and number of As as the row, we find which character each section represents:

Section    | Num Os | Num As | Character

gogooa     | 2      | 1      | (2,1) -> H
gagooook   | 4      | 0      | (4,0) -> E
aagaaoooy  | 3      | 4      | (3,4) -> Y

Which tells us that the baby was just saying "HEY".

Notes:
- If a section representing a character has more than 4 As or Os, ignore the extras, because 4 is the maximum value on the table. - For this task, Y is not a vowel - only A, E, I, O and U.

The Challenge

Your task is to create a full program which takes one input, a word in baby-speak, and prints it in plaintext.

  • Your program must be able to take input in uppercase, lowercase, and a mix of both.
  • The input will only contain ASCII alphabet letters (A-Z and a-z), with single spaces to seperate the baby words.
  • The output text can be in any case.
  • You should the take the input from STDIN and print the plaintext on STDOUT. If your language does not have these, use the nearest equivalent.
  • This is , so the shortest code in bytes wins - but any solution is welcome.

Try it online!

Explanation in steps

  1. split on spaces to form words
  2. replace konsonants in words with spaces
  3. split words on spaces to form groups of vowels
  4. remove vowel groups with a length shorter than 2
  5. get min of count(a) and 4, multiply by 5
  6. get min of count(o) and 4
  7. add counts
  8. get letter at that index of alphabet (excluding "j")

Perl, 82 bytes

Includes +1 for -a

Give input on STDIN:

perl -M5.010 baby.pl <<< "OOaGOG GoGOOoGoU gAA bLAA GOUGoOUgAIGAI"

baby.pl:

#!/usr/bin/perl -a
say map{$A=$O=$_=uc;y/AEIOU/@/c;s/(\B.|.\B)/$$1+=$$1<4/eg;(A..I,K..Z)[5*$A+$O]}@F

This assumes a recent enough perl version where -a implies -n. If your perl is too old you will need to add an explicit -n option.

It also assumes babies can't say general ASCII strings that start with digits like 1 this will not work

This was a pretty good way to kill a couple of hours.

Requires a brainfuck interpreter that uses 8-bit wrapping cells, allows you to go left from cell 0 and returns 0 if , is used when stdin is empty. In my experience, these are the most common settings.

This program does not consider Y a vowel, but if OP wants it to it's an easy fix.

It seems like writing this would be a daunting task but if you have some familiarity with the language there's nothing surprising or new in the code. Standard brainfuck tactics: Read the input but make sure you leave a couple of empty cells between each byte, use those empty cells to store data about the input, use the data you stored to decide how to transform it and spit something out at the end. In this case it was get the input, set it all to uppercase, figure out which cells are vowels, throw that information away after using it to determine which cells are next to vowels, set everything that isn't next to a vowel to some value that will never be relevant so they're not in the way later, and you're basically done. From there you just have to count your As and Os, multiply As by 5 and add the number of Os, special case anything above 8 to avoid J and output. I did choose to handle this one word at a time, rather than taking the whole input at once, so I had to set up the part of the code that reads stdin to break at 0 or 32, but that's not too big of a problem (just wrap the subtraction by 32 in a conditional so it doesn't happen if the value is already 0, then correct for any < or > instructions you missed later).

I don't know how helpful it will be because I wrote it mostly to keep my thoughts straight rather than as a real explanation, but here's the code with my comments and its original indentation:

+[[>>>,[>++++[<-------->-]]<]get an entire word of input
                            each character lowered by 32
                            two empty cells between characters
                            stops when reaching a space or null byte

any lowercase letters have become uppercase; anything with a value below 65 used
to be an uppercase character; fix it

<<[>]<-[+                for each character until hitting 1:
  [<+>>+<-]              make a backup
  subtract 64 from the character but stop if it hits 0
  ----[>>+<<----]>>+     generate the number 64
  [                      64 times:
    <[                     if the character is not 0:
      -                    subtract 1
      <                    go to a guaranteed 0 cell to break the loop
    ]

Perl, 159 +1 = 160 bytes

+1 byte for -n flag. Whitespace is not part of the code and is only provided for readability.

for(split$",lc){
    $b=0;
    @a=sort/([ao](?=[aeiou])|(?<=[aeiou])[ao])/g;
    $b++until$b>$#a||$a[$b]eq o;
    $c=($d=$#a-$b+1)>4?4:$d;
    $b=$b>4?4:$b;
    print+(a..i,k..z)[5*$b+$c];
}

The code splits the input by spaces and converts each baby word to lowercase before proceeding. The regex finds all a or o vowels that are followed by another vowel, or are preceeded by a vowel, and sorts them, a's at the start, o's at the end, then finds the index of the first 'o'. If the remaining number of matches (aka, the number of 'a's) is greater than 4, then we care about 4 a's, and if there are more than 4 o's, we care about 4 o's. Then it pulls the appropriate letter out of the matrix and prints it, then moves onto the next baby word.

This works with or without a trailing newline in the input.

Try it online.

Each character is processed mod 32 (with control flow such that the code implementing the mod operation only occurs once in the program). This enables case insensitivity, as well as collapsing the space character and EOF into a single case. A trailing newline is treated the same as J, which doesn't affect the output.

Sketch of memory layout:

0 x C c y a A b B

where c is the input character, C is the char mod 32, x is whether it is a vowel, y is whether the previous char was a vowel, A and B are the counts of valid (next to vowels) a and o chars respectively, and a and b are their respective buffers that get copied or cleared depending on whether there is an adjacent vowel.

When a space or EOF is reached, some juggling is done to reduce counts greater than 4 and to skip the letter J, and then the decoded character is printed.

Uses regex to find all string of vowels larger than 2, counts As and Os with maximum of 4, and then prints.

APL, 60

{⎕A[a+9<a←5⊥+/¨'ao'∊⍨¨⊂⍵/⍨0(,∨,⍨)2∧/⍵∊'aeiou']}¨' '(≠⊂⊢)819⌶

Note that ⎕IO←0 and ⎕ML←3

Example:

fn←{⎕A[a+9<a←5⊥+/¨'ao'∊⍨¨⊂⍵/⍨0(,∨,⍨)2∧/⍵∊'aeiou']}¨' '(≠⊂⊢)819⌶
fn 'Aoao U oOOAoa oaoAoo aoAoAOa'
NAPPY

Works in Dyalog 15.0, since it's the version in which 819⌶ was introduced to lowercase a string.

R, 261 bytes

I think I spent way too much time just to get this working and I believe this is an unnecessarily complicated solution, although it works. Takes input from stdin, it's important that the string is enclosed in quotes.

x=el(strsplit(toupper(scan(,""))," "))
cat(apply(sapply(c("A","O"),function(y)sapply(sapply(regmatches(x,gregexpr("[AEIOU]{2,}",x,)),paste,collapse=""),function(s)min(sum(el(strsplit(s,""))%in%y),4)))+1,1,function(z)t(matrix(LETTERS[-10],5))[z[1],z[2]]),sep="")

The use of four nested apply-family could theoretically be reduced to only two by making use of mapply instead. But because inputs to mapply will not be of the same length, the shorter one is recycled which complicates things and I couldn't figure out a working solution.

If anyone is interested I'll add an ungolfed explanation later.

Try all the test cases on R-fiddle

Please note that this version takes input as a function argument instead from stdin because scan doesn't work on R-fiddle. Furthermore, added a newline to make it easier to read.

Less Golfed (The comments are the variables in the shortened code):

babyTalk = input('Baby Talk: ').lower() #b
vowels = 'aeiou' #v
numbers = list(range(26)) #n
del numbers[9]
letters = 'abcdefghiklmnopqrstuvwxyz' #l

for word in babyTalk.split(): #w in b
 Os = len(findAll('o[aeiou]', word)) + len(findAll('[aeiou]o', word)) #O
 As = len(findAll('a[aeiou]', word)) + len(findAll('[aeiou]a', word)) #A
 if Os > 4: Os = 4
 if As > 4: As = 4
 print(As, Os)
 finalText += letters[As*5+Os]

  • \$\begingroup\$ This doesn't work for a word blaoaoaog: the interlaced vowels are counted more than once, giving z when it should be t (though it does work on just aaaooo, though I cannot figure out why....) \$\endgroup\$ – CAD97 Nov 2 '16 at 1:13
  • \$\begingroup\$ @CAD97 Are you saying that aooa should be p, not n? \$\endgroup\$ – nedla2004 Nov 2 '16 at 1:50
  • \$\begingroup\$ not on purpose; aooa == (2,2) == n, aoaoao == (3,3) == t \$\endgroup\$ – CAD97 Nov 2 '16 at 2:11
  • \$\begingroup\$ just tested it and CAD is correct, gaoaoaog prints Z instead of T. I think it's because your regex is picking up [ao,oa,ao,oa,ao], which counts 5,5, then constricts it to 4,4, printing Z. \$\endgroup\$ – FlipTack Nov 2 '16 at 20:48

Kotlin, 221 209 bytes

Now much more ugly and slow, all in the name of 11 bytes

readLine()!!.toLowerCase().split(" ").map{fun
c(c:Char)=Regex("([aeiou]{2,})").findAll(it).fold(0){a,b->a+b.value.count{it==c}}.let{if(it>4)4 else it}
(('A'..'I')+('K'..'Z'))[c('a')*5+c('o')]}.forEach(::print)

Save it to a file (ex. BabyTalk.kts) to run as a script. Or, the above code can be prepended with fun main(z:Array<String>)= and compiled normally for a cost of 26 more bytes.

Indented:

readLine()!!
    .toLowerCase()
    .split(" ")
    .map {
        fun c(c: Char) =
            Regex("([aeiou]{2,})")
                .findAll(it)
                .fold(0) {
                    a, b ->
                    a + b.value.count { it == c }
                }
                .let { if (it > 4) 4 else it }
        (('A'..'I') + ('K'..'Z'))[c('a') * 5 + c('o')]
