# THE WAXHOLM CORPUS

The Waxholm corpus was collected in 1993 - 1994 at the department of
Speech, Hearing and Music (TMH), KTH. It is described in several
publications. Two are included in this archive. Publication of work
using the Waxholm corpus should refer to either of these. More
information on the Waxholm project can be found on the web page
http://www.speech.kth.se/waxholm/waxholm2.html


## FILE INFORMATION

### SAMPLED FILES
The .smp files contain the speech signal. The identity
of the speaker is coded by the two digits after 'fp20' in the file
name. The smp file format was developed by TMH. Recording information
is stored in a header as a 1024 byte text string. The speech signal in
the Waxholm corpus is quantised into 16 bits, 2 bytes/sample and the
byte order is big-endian (most significant byte first). The sampling
frequency is 16 kHz. Here is an example of a file header:

```
>head -9 fp2001.1.01.smp
file=samp               ; file type is sampled signal
msb=first               ; byte order
sftot=16000             ; sampling frequency in Hz
nchans=1                ; number of channels
preemph=no              ; no signal preemphasis during recording
view=-10,10
born=/o/libhex/ad_da.h25
range=-12303,11168      ; amplitude range
=
```


### LABEL FILES 
Normally, each sample file has a label file. This has been
produced in four steps. The first step was to manually enter the
orthographic text by listening. From this text a sequence of phonemes
were produced by a rule-based text-to-phoneme module. The endpoint
time positions of the phonemes were computed by an automatic alignment
program, followed by manual correction.  Some of the speech files have
no label file, due to different problems in this process. These files
should not be used for training or testing.

The labels are stored in .mix files. Below is an example of the
beginning of a mix file.

```


The orthographic text representation is after the label 'TEXT:' CT is
the frame length in number of sample points. (Always = 1 in Waxholm
mix files) Each line starting with 'FR' contains up to three labels at
the phonetic, phonemic and word levels.  FR is immediately followed by
the frame number of the start of the segment. Since CT = 1, FR is the
sample index in the file. If a frame duration is = 0, the label has
been judged as a non-pronounced segment and deleted by the manual
labeller, although it was generated by the text-to-phoneme or the
automatic alignment modules.  Column 3 in an FR line is the phonetic
label. Initial '#' indicates word initial position. '$' indicates
other positions. The optional label '>pm' precedes the phonemic label,
which has been generated by the text-to-phoneme rules. Often, the
phonemic and the phonetic labels are identical. The optional '>w' is
followed by the identity of the word beginning at this frame.  The
phoneme symbol inventory is mainly STA, used by the KTH/TMH RULSYS
system. It is specified in the included file 'sampa_latex_se.pdf'.

Some extra labels at the phonetic level have been defined. 
The most common ones are:

|                     |                                          |

|pa                   | aspirative sound from breathing          |
|kl                   | click sound                              |
|v                    | short vocalic segment between consonants |
|upper case of stops  | occlusion                                |
|lower case of stops  | burst                                    |

The label 'Labels:' before the FR lines is a text string assembled
from the FR labels

The mix files in this archive correspond to those with the name
extension .mix.new in the original corpus. Besides a few other
corrections, the main difference is that burst segments after
retroflex stops were not labelled as retroflex in the original .mix
files ( d, t after 2D and 2T have been changed to 2d and 2t).
