분실 - 일상

아이들은 아직 xbox controller 가 무엇인지 알지 못한다.
나의 책상에는 여러 집기 들이 있지만 xbox controller 는 아이의 눈으로도 가지고 노는 물건으로 보인 것에 틀림 없다.
그렇게 책상에 올려두었다는 이유로 나의 xbox controller 는 어디론가 사라져버렸다.
안녕, Dead cells !

timit phone set (61 to 39) - 컴퓨터

ref: http://cdn.intechopen.com/pdfs/15948/InTech-Phoneme_recognition_on_the_timit_database.pdf
Timit[1] data set originally contains 61 phones but in Graves RNN-T paper [2] and in many other pieces of literature use 39 phoneme sets.
Here is a mapping table from 61 classes to 39 classes, as proposed by Lee and Hon[3].
You can find the table far below. I'll fix it later..;

aa, ao	aa
ah, ax, ax-h	ah
er, axr	er
hh, hv	hh
ih, ix	ih
l, el	l
m, em	m
n, en, nx	n
ng, eng	ng
sh, zh	sh
uw, ux	uw
pcl, tcl, kcl, bcl, dcl, gcl, h#, pau, epi	sil
q	-

1. Decoding module
2. input noise, then can fully reproduce the RNN-T paper.
3. peephole, then can fully reproduce the CTC paper.

Timit data preperation..

prep timit dataset accoring to the RNN-T paper..
- train 3512
- valid 184 (drawn from training set) why...?
- test 192
but .. Timit composes of 4620 training, 1680 test uttrances..
