segs/ contains the raw data from the FOI to Irish Rail
wavs/ contains decoded audio from the .seg files
mp3s/ contains the decoded audio in MP3 format for wider compatibility and lower file size
renamed/ contains the MP3 files for each voice, renamed and grouped using their transcriptions csv file

Each of the above folders contains various voice packs supplied or managed by KeTech.

The most well-known are likely Phil Sayer and Celia Drummond due to their extensive coverage of the UK railway network during their time as announcers for the KeTech, Amey and Ditra customer information systems.

Folder name	Common name
`Male1`	Phil Sayer
`Male3` and `default`	Michael Comyn (Irish Rail)
`Female1`	Celia Drummond

Decoding .seg files

A kind user on RailForums managed to work out a method of decoding the "proprietary" format.

On Debian/Ubuntu:

sudo apt install sox
find -iname "*.SEG" -exec bash -c "tail -c +48 '{}' | sox -t raw -b 8 -r 16000 -e a-law -X - '{}.wav'" \;

This command:

Iterates over every .SEG file
Provides the content of each file, skipping the first 48 bytes, to sox
sox then converts the audio into a more widely used .wav format

Converting to mp3

On Linux:

sudo apt install parallel
find "$(pwd)" -type f -name "*.wav" | parallel 'ffmpeg -y -hide_banner -loglevel error -i "{}" -q:a 0 "$(dirname "{}")/$(basename "{}" .wav).mp3"'

Renaming files to remove `.seg`/`.wav`

On Linux:

sudo apt install rename
rename 's/\.SEG|\.seg//' *
rename 's/\.WAV|\.wav//' *

.seg file format

Most seg files start with a 48 character header, e.g. 1483 12FF

The first four characters are a space padded ID (which may be absent, or padded with zeroes instead of spaces), the last four characters are mandatory, are in hexadecimal range, and may be uppercase or lowercase. The ID will usually (but not always) match the filename.

A very small number also include a transcription.

Examples:

1483 12FF
130 FFFF
12ff
2456 a security alert.04FF
0400 FFFF
2439 FROM8440

Unusual .seg files

A small number of the .seg files contain strange header contents that don't match this pattern in some way, or have odd file descriptions.

File	Description
segs/default/306.seg	`FFFF\x9d` only
segs/default/1871.seg	`ffff` only
segs/default/199.seg	`FFFFt` only
segs/Male3/306.seg	`FFFF\x9d` only
segs/Male3/199.seg	`FFFFt` only
segs/Male1/399.seg	`399ader->End,HeaderEnd,3); /*RecoFFFF`, ...
segs/Female2/0.seg	Header is correct length, but is padded with null bytes instead of spaces, ends `FFFF`
segs/Female2/1400.seg	Has no header

Missing files

For Phil and Celia, some modern-day stations are missing from their announcements. Many of these opened after their recordings were made.

Some of these stations have been bodged by combining clips from other snippets together, but some are still unrecorded.
