Compiling
|
|
=========
|
|
|
|
The src directory contains a makefile that produces:
|
|
|
|
1. "libspeak.so.1.xx". (where xx is a version number)
|
|
This is a shared library which contains the text to speech engine.
|
|
Its API is described in the file "speak_bin.h".
|
|
|
|
2. "espeak" binary. This is a small command-line program which is a front
|
|
end to the libespeak library, which it needs.
|
|
|
|
3. "speak" binary. This is a command-line program which contains the
|
|
text to speech engine. It does not use the libespeak library.
|
|
|
|
|
|
When run, the "speak" and "espeak" programs expect to find the espeak-data
|
|
directory either in the user's home directory, or if not there, in /use/share.
|
|
|
|
|
|
Portaudio.
|
|
==========
|
|
|
|
The "speak" program uses the PortAudio sound interface library. There are two
|
|
versions, V18 and V19 and their APIs are different. Some Linux distributions
|
|
use V18 (eg. Debian, Ubuntu) others (eg. SuSe) use V19.
|
|
|
|
To compile to use a particular version of the PortAudio library, first copy
|
|
either portaudio18.h or portaudio19.h to portaudio.h.
|
|
|
|
If you don't need eSpeak to output sound, but only to produce WAV files,
|
|
then you can remove or comment out the following line in speech.h.
|
|
This will mean that eSpeak doesn't use any PortAudio functions.
|
|
#define USE_PORTAUDIO
|
|
|

|
Compiling Data
|
|
==============
|
|
|
|
You can modifiy spelling-to-phoneme rules and exceptions and re-compile this
|
|
data with the speak program (see docs/dictionary.html). In summary, edit
|
|
the dictsource/**_rules and dictsource/**_list files and compile using:
|
|
espeak --compile=**
|
|
where ** is the language code (eg. en for English).
|
|
|
|
In order to modify the sounds or other characteristics of phonemes, or
|
|
to add additional phonemes, another program "espeakedit" is needed. This
|
|
is provided in a separate package.
|
|
|
|
|
|
PowerPC and Big-Endian Processors
|
|
=================================
|
|
|
|
The compiled data in the espeak-data directory is not binary compatible between
|
|
processors with different byte ordering. For a PowerPC or other big-endian
|
|
processor use must use data which has been compiled (using espeakedit) on
|
|
a big-endian processor.
