TIMIT语音库（转）
TIMIT语音库为大多数论文及研究中常用的语音库，适用于语音识别、说话人识别等语音信号处理。在MIT网站可以找到一些， 为 16kHz sampling, 16 bit sample, PCM encoding。样例才160个句子，不够用。这儿能找到，用抓取工具全部下载下来有600多M但问题是虽然其为wav结尾，matlab中wavread却读不了，用二进制打开文件发现&google一下，原来其为&整个语音库有6300个文件，如何全部转换为普通的wav文件？step1&遍历整个文件夹，把所有wav文件全找出来&find_wav.mfunction [ wav_files ] = find_wav( path )%FIND_WAV, find all wav file recursivelywav_files = [];if(isdir(path) == 0)endpath_files = dir(path);fileNum = length(path_files);for k= 3:fileNum

&&&&&&&&& The DARPA TIMIT Acoustic-Phonetic Continuous Speech Corpus
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& (TIMIT)
&&&&&&&&&&&&&&&&&&&&&&&&&&& Training and Test Data
&&&&&&&&&&&&&&&&&&&&&&&&&& NIST Speech Disc CD1-1.1
The TIMIT corpus of read speech has been designed to provide speech data for
the acquisition of acoustic-phonetic knowledge and for the development and
evaluation of automatic speech recognition systems.& TIMIT has resulted from
the joint efforts of several sites under sponsorship from the Defense Advanced
Research Projects Agency - Information Science and Technology Office
(DARPA-ISTO).& Text corpus design was a joint effort among the Massachusetts
Institute of Technology (MIT), Stanford Research Institute (SRI), and Texas
Instruments (TI).& The speech was recorded at TI, transcribed at MIT, and has
been maintained, verified, and prepared for CD-ROM production by the National
Institute of Standards and Technology (NIST).& This file contains a brief
description of the TIMIT Speech Corpus.& Additional information including the
referenced material and some relevant reprints of articles may be found in the
printed documentation which is also available from NTIS (NTIS# PB91-100354).
1. Corpus Speaker Distribution
-- ---------------------------
TIMIT contains a total of 6300 sentences, 10 sentences spoken by each of 630
speakers from 8 major dialect regions of the United States.& Table 1 shows the
number of speakers for the 8 dialect regions, broken down by sex.& The
percentages are given in parentheses.& A speaker's dialect region is the
geographical area of the U.S.& where they lived during their childhood years.
The geographical areas correspond with recognized dialect regions in U.S.
(Language Files, Ohio State University Linguistics Dept., 1982), with the
exception of the Western region (dr7) in which dialect boundaries are not
known with any confidence and dialect region 8 where the speakers moved around
a lot during their childhood.
&& Table 1:& Dialect distribution of speakers
&&&&& Dialect
&&&&& Region(dr)&&& #Male&&& #Female&&& Total
&&&&& ----------& --------- ---------& ----------
&&&&&&&& 1&&&&&&&& 31 (63%)& 18 (27%)&& 49 (8%)&
&&&&&&&& 2&&&&&&&& 71 (70%)& 31 (30%)& 102 (16%)
&&&&&&&& 3&&&&& &&&79 (67%)& 23 (23%)& 102 (16%)
&&&&&&&& 4&&&&&&&& 69 (69%)& 31 (31%)& 100 (16%)

&&&&&& ------&&&& --------- ---------& ----------
&&&&&&&& 8&&&&&&& 438 (70%) 192 (30%)& 630 (100%)
The dialect regions are:
&&&& dr1:& New England
&&&& dr2:& Northern
&&&& dr3:& North Midland
&&&& dr4:& South Midland
&&&& dr5:& Southern
&&&& dr6:& New York City
&&&& dr7:& Western
&&&& dr8:& Army Brat (moved around)
2. Corpus Text Material
-- --------------------
The text material in the TIMIT prompts (found in the file &prompts.doc&)
consists of 2 dialect &shibboleth& sentences designed at SRI, 450
phonetically-compact sentences designed at MIT, and 1890 phonetically-diverse
sentences selected at TI.& The dialect sentences (the SA sentences) were meant
to expose the dialectal variants of the speakers and were read by all 630
speakers.& The phonetically-compact sentences were designed to provide a good
coverage of pairs of phones, with extra occurrences of phonetic contexts
thought to be either difficult or of particular interest.& Each speaker read 5
of these sentences (the SX sentences) and each text was spoken by 7 different
speakers.& The phonetically-diverse sentences (the SI sentences) were selected
from existing text sources - the Brown Corpus (Kuchera and Francis, 1967) and
the Playwrights Dialog (Hultzen, et al., 1964) - so as to add diversity in
sentence types and phonetic contexts.& The selection criteria maximized the
variety of allophonic contexts found in the texts.& Each speaker read 3 of
these sentences, with each sentence being read only by a single speaker.
Table 2 summarizes the speech material in TIMIT.
&&& Table 2:& TIMIT speech material
& Sentence Type&& #Sentences&& #Speakers&& Total&& #Sentences/Speaker
& -------------&& ----------&& ---------&& -----&& ------------------
& Dialect (SA)&&&&&&&&& 2&&&&& &&&630&&&&&& 1260&&&&&&&&&& 2
& Compact (SX)&&&&&&& 450&&&&&&&&&& 7&&&&&& 3150&&&&&&&&&& 5

& -------------&& ----------&& ---------&& -----&&& ----------------
& Total&&&&&&&&&&&&& 2342&&&&&&&&& &&&&&&&&&6300&&&&&&&&& 10
3. Suggested Training/Test Subdivision
-- -----------------------------------
The speech material has been subdivided into portions for training and
testing.& The criteria for the subdivision is described in the file
&testset.doc&.& THIS SUBDIVISION HAS NO RELATION TO THE DATA DISTRIBUTED ON
THE PROTOTYPE VERSION OF THE CDROM.
Core Test Set:
The test data has a core portion containing 24 speakers, 2 male and 1 female
from each dialect region.& The core test speakers are shown in Table 3.& Each
speaker read a different set of SX sentences.& Thus the core test material
contains 192 sentences, 5 SX and 3 SI for each speaker, each having a distinct
text prompt.
&&& Table 3:& The core test set of 24 speakers
&&&& Dialect&&&&& &&Male&&&&& Female
&&&& -------&&&&&& ------&&&& ------
&&&&&&& 1&&&&&&& DAB0, WBT0&&& ELC0&&&
&&&&&&& 2&&&&&&& TAS1, WEW0&&& PAS0&&&
&&&&&&& 3&&&&&&& JMP0, LNT0&&& PKT0&&&
&&&&&&& 4&&&&&&& LLL0, TLS0&&& JLM0&&&
&&&&&&& 5&&&&&&& BPM0, KLT0&&& NLP0&&&
&&&&&&& 6&&&&&&& CMJ0, JDH0&&& MGD0&&&
&&&&&&& 7&&&&&&& GRT0, NJM0&&& DHC0
&&&&&&& 8&&&&&&& JLN0, PAM0&&& MLD0&&&
Complete Test Set:
A more extensive test set was obtained by including the sentences from all
speakers that read any of the SX texts included in the core test set.& In
doing so, no sentence text appears in both the training and test sets.& This
complete test set contains a total of 168 speakers and 1344 utterances,
accounting for about 27% of the total speech material.& The resulting dialect
distribution of the 168 speaker test set is given in Table 4.& The complete
test material contains 624 distinct texts.
&&&& Table 4:& Dialect distribution for complete test set
&&&&& Dialect&&& #Male&& #Female&& Total
&&&&& -------&&& -----&& -------&& -----

Online documentation and tables are located in the directory &timit/doc&.
A brief description of each file in this directory can be found in Section 6.
5. File Types
-- ----------
The TIMIT corpus includes several files associated with each utterance.& In
addition to a speech waveform file (.wav), three associated transcription
files (.txt, .wrd, .phn) exist.& These associated files have the form:
&&&&&&& &BEGIN_SAMPLE& &END_SAMPLE& &TEXT&&new-line&
&&&&&&& &BEGIN_SAMPLE& &END_SAMPLE& &TEXT&&new-line&
&&&&&&& where,&&&&&&&
&&&&&&&&&&&&&&& BEGIN_SAMPLE :== The beginning integer sample number for the
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& segment (Note: The first BEGIN_SAMPLE of each
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& file is always 0)
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&
&&&&&&&&&&&&&&& END_SAMPLE :== The ending integer sample number for the segment
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& (Note: Because of the transcription method used,
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& the last END_SAMPLE in each transcription file
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& may be less than the actual last sample in the
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& corresponding .wav file)
&&&&&&&&&&&&&&& TEXT :== &ORTHOGRAPHY& | &WORD_LABEL& | &PHONETIC_LABEL&
&&&&&&&&&&&&&&&&&&&&&&&&
&&&&&&&&&&&&&&& where,
&&&&&&&&&&&&&&&
&&&&&&&&&&&&&&&&&&&& ORTHOGRAPHY :== Complete orthographic text transcription
&&&&&&&&&&&&&&&&&&&& WORD_LABEL :== Single word from the orthography
&&&&&&&&&&&&&&&&&&&& PHONETIC_LABEL :== Single phonetic transcription code
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& (See &phoncode.doc& for description
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& of codes)
&&& Table 5:& Utterance-associated file types&&&&&&&&&
&File Type&&&&&&&&&&&&&&&&&&&& Description

&&&& .wav - SPHERE-headered speech waveform file.& (See the &/sphere&
&&&&&&&&&&& directory for speech file manipulation utilities.)
&&&& .txt - Associated orthographic transcription of the words the
&&&&&&&&&&& person said.& (Usually this is the same as the prompt, but
&& &&&&&&&&&in a few cases the orthography and prompt disagree.)
&&&& .wrd - Time-aligned word transcription. The word boundaries
&&&&&&&&&&& were aligned with the phonetic segments using a dynamic
&&&&&&&&&&& string alignment program (see the printed documentation
&&&&&&&&&&& section &Notes on the Word Alignments& and the lexical
