Diphone Studio is a tool for developing and maintaining 
a set of diphones for use in speech synthesis. A diphone 
is the transition between two speech sounds, obtained 
from natural speech. A diphone synthesizer creates new 
utterances by concatenation of diphones, modifying pitch 
and duration of each sound according to some specification.

A diphone set is created in a number of steps:

1. Specification of a phoneme inventory
2. Creation of a corpus
3. Recording the corpus
4. Segmentation of the corpus
5. Preliminary evaluation
6. Post-processing

Diphone Studio is designed to facilitate steps 3 through 5. 
The program was specifically designed for the creation of 
diphone databases for the MBROLA synthesizer, developed 
by Thierry Dutoit and colleagues at the Faculté Polytechnique 
de Mons. For more information about the MBROLA synthesizer see

Diphone Studio runs under Windows 95/98/NT, and
requires a Windows-compatible 16-bit sound card.

The program is distributed as a .ZIP file, usually
called DSTUDIO.ZIP

To install the program, you will need PKUNZIP.EXE (or
an equivalent program, such as WINZIP):

1. Create a directory for the program and change to
it

2. Unpack DSTUDIO.ZIP to this directory. Make sure
subdirectories contained in the .ZIP file are restored.
For example, if you use PKUNZIP, the command to unpack
is:

	pkunzip -d dstudio

To test the program:

1. From Windows, start DSTUDIO.EXE

2. From the menu, select File|Open. Next, select the 
subdirectory EXAMPLE, and from this directory select
EXAMPLE.DAT. This loads a small diphone database.

3. The on-line help will guide you from here.
