NAME
       espeak-ng - A multi-lingual software speech synthesizer.

SYNOPSIS
       espeak-ng [options] [words]

DESCRIPTION
       espeak-ng  is a software	speech synthesizer for English,	and some other
       languages.

OPTIONS
       -h, --help
	      Show summary of options.

       --version
	      Prints the espeak	library	version	and the	location of the	espeak
	      voice data.

       -f <text	file>
	      Text file	to speak.

       --stdin
	      Read text	input from stdin till to the end of a stream at	once.

       If neither -f nor --stdin are provided, then <words> from parameter are
       spoken, or text is spoken from stdin, read separately one line by  line
       at a time.

       -d <device>
	      Use  the	specified  device to speak the audio on. If not	speci-
	      fied, the	default	audio device is	used.

       -q     Quiet, don't produce any speech (may be useful with -x).

       -a <integer>
	      Amplitude, 0 to 200, default is 100.

       -g <integer>
	      Word gap.	Pause between words, units  of	10ms  at  the  default
	      speed.

       -k <integer>
	      Indicate	capital	 letters with: 1=sound,	2=the word "capitals",
	      higher values = a	pitch increase (try -k20).

       -l <integer>
	      Line length. If not zero (which is the default), consider	 lines
	      less than	this length as end-of-clause.

       -p <integer>
	      Pitch adjustment,	0 to 99, default is 50.

       -s <integer>
	      Speed in words per minute, default is 175.

       -v <voice name>
	      Use  voice file of this name from	espeak-ng-data/voices. A vari-
	      ant can be specified using voice+variant,	such as	af+m3.

       -w <wave	file name>
	      Write output to this WAV file, rather than speaking it directly.

       --split=<minutes>
	      Used with	-w to split the	audio output into  <minutes>  recorded
	      chunks.

       -b     Input text encoding, 1=UTF8, 2=8 bit, 4=16 bit.

       -m     Indicates	 that  the text	contains SSML (Speech Synthesis	Markup
	      Language)	tags or	other XML tags.	Those SSML tags	which are sup-
	      ported are interpreted. Other tags, including HTML, are ignored,
	      except that some HTML tags such as <hr> <h2> and <li>  ensure  a
	      break in the speech.

       -x     Write phoneme mnemonics to stdout.

       -X     Write  phonemes  mnemonics  and  translation trace to stdout. If
	      rules files have been built with --compile=debug,	 line  numbers
	      will also	be displayed.

       -z     No final sentence	pause at the end of the	text.

       --stdout
	      Write speech output to stdout.

       --compile=voicename
	      Compile  the  pronunciation  rules and dictionary	in the current
	      directory. =<voicename< is optional and specifies	which language
	      is compiled.

       --compile-debug=voicename
	      Compile the pronunciation	rules and dictionary  in  the  current
	      directory	 as  above,  but  include line numbers,	that get shown
	      when -X is used.

       --ipa  Write phonemes to	stdout using International Phonetic  Alphabet.
	      --ipa=1 Use ties,	--ipa=2	Use ZWJ, --ipa=3 Separate with _.

       --tie=<character>
	      The  character  to  use  to join multi-letter phonemes in	-x and
	      --ipa output.

       --path=<path>
	      Specifies	the directory containing the espeak-ng-data directory.

       --pho  Write mbrola phoneme data	(.pho) to stdout or  to	 the  file  in
	      --phonout.

       --phonout=<filename>
	      Write output from	-x -X commands and mbrola phoneme data to this
	      file.

       --punct="<characters>"
	      Speak  the  names	 of punctuation	characters during speaking. If
	      =<characters> is omitted,	all punctuation	is spoken.

       --sep=<character>
	      The character to separate	phonemes from the -x and --ipa output.

       --voices[=<language code>]
	      Lists the	available voices. If =<language	code> is present  then
	      only  those  voices  which  are  suitable	 for that language are
	      listed. If xx-yy language	code is	passed,	then voices with yy of
	      xx language variants are shown with higher  priority  than  just
	      xx.  If variant is passed, then all voice	variants are shown. If
	      mb or mbrola is passed, then all voices using the	 MBROLA	 voice
	      synthesizer  are	shown.	If  all	 is passed, then all eSpeak NG
	      voices, voice variants and MBROLA	voices are shown.

       --voices=<directory>
	      Lists the	voices in the specified	subdirectory.
