However, when I tried it out I get strange results...
//someString is set to different strings each time tested
BOOL test = [someString soundsLikeString:@"Face"];
NSLog(@"sounds like Face: %d",test);
Place = 0
Ace = 0
Mace = 0
Fake = 1
Testing = 0
Brake = 0
It would seem something is off to get negatives on Place, Ace & Mace.
There's this comment in the -soundexString method:
Replace consonants with digits as follows (but do not change the
first letter):
b, f, p, v => 1
c, g, j, k, q, s, x, z => 2
d, t => 3
l => 4
m, n => 5
r => 6
Collapse adjacent identical digits into a single digit of that value.
Remove all non-digits after the first letter.
Return the starting letter and the first three remaining digits. If
needed, append zeroes to make it a letter and three digits.
Assuming the code works as the comment says, and you should read the
code to confirm this, then it doesn't change the first letter. So it
seems to me that "Face" won't match place, ace, or mace.
Maybe you could print the value of the -soundexString method instead
of blindly relying on the boolean of soundsLikeString:.
