SYNOPSISespeak [option...] [words]
DESCRIPTIONespeak is a compact open source software speech synthesizer. It can
run as a command line program to speak text from a file or from stdin.
Main features of espeak:
* Includes different voices, whose characteristics
can be altered.
* Can produce speech output as a WAV file.
* Supports SSML (Speech Synthesis Markup Language
- not complete)
* Supports HTML.
* Is compact in size.
* Can translate text to phoneme codes, so it could
be adapted as a front end for another speech
synthesis engine.
* Is written in C++.
OPTIONS
The following options are supported:
-a integer Amplitude as an integer in the range from 0 to
200, default is 100.
-b Input text is 8-bit encoded.
-f text_file Speak text from text_file.
-g integer Specify the word gap, or the pause between
words, as an integer. Units of 10mS at the
default speed.
-k integer Indicate how to speak capital letters as an
integer. The argument can have the following
values: 1=sound, 2=the word "capitals", higher
values=a pitch increase (try -k 20).
-l integer Line length as an integer. If not zero (which
is the default), consider lines less than this
length as end-of-clause.
-m Interpret SSML markup, and ignore other < >
tags.
-p integer Pitch adjustment as an integer in the range
from 0 to 99, default is 50.
-q Quiet, do not produce any speech (may be useful
with -x).
-s integer Speed as an integer meaning words per minute.
Values can be from 80 to 370, default is 170.
-v voice_file Use specified voice_file.
-w filename Write output to the specified filename, in WAV
format, rather than speaking it directly.
-x Write phoneme mnemonics to stdout.
-X Write phonemes mnemonics and translation trace
to stdout.
-z No final sentence pause at the end of the text.
--compile=voice_name Compile the pronunciation rules and dictionary
in the current directory. The voice_name value
is optional and specifies which language to
use.
--punct="characters" Speak the names of punctuation characters while
speaking. If the characters value is omitted,
all punctuation is spoken.
--split=minutes Starts a new WAV file every minutes. Used with
-w.
--stdin Read text input from stdin instead of a file.
--stdout Write speech output to stdout.
--voices=language List the available voices for the specified
language. If language is omitted, then list
all voices.
