 Once the language's phonemes have been defined, then pronunciation dictionary data can be produced in order to translate the language's source text into phonemes. This consists of two source files: <B>fr_rules</B> (the spelling to phoneme rules) and <B>fr_list</B> (an exceptions list, and attributes of certain words). The corresponding compiled data file is <B>espeak-data/fr_dict</B> which is produced from <B>fr_rules</B> and <B>fr_list</B> sources by the command:

 <h3>2.1.1 Linux and other Posix systems</h3>
 There are two versions of the command line program. They both have the same command parameters (see below).
 <ol>
-<li><strong>espeak</strong> uses speech engine in the <strong>libespeak</strong> shared library.  The libespeak library must first be installed.
+<li><strong>espeak-ng</strong> uses speech engine in the <strong>libespeak-ng</strong> shared library.  The libespeak-ng library must first be installed.
 <p>
-<li><strong>speak</strong> is a stand-alone version which includes its own copy of the speech engine.
+<li><strong>speak-ng</strong> is a stand-alone version which includes its own copy of the speech engine.
 </ol>
-Place the <strong>espeak</strong> or <strong>speak</strong> executable file in the command path, eg in <strong>/usr/local/bin</strong>
+Place the <strong>espeak-ng</strong> or <strong>speak-ng</strong> executable file in the command path, eg in <strong>/usr/local/bin</strong>
 <p>
 Place the "<strong>espeak-data</strong>" directory in /usr/share as <strong>/usr/share/espeak-data</strong>.<br>
 Alternatively if it is placed in the user's home directory (i.e. <strong>/home/&lt;user&gt;/espeak-data</strong>)
 then that will be used instead.
 <p>
 <h4>Dependencies</h4>
-<strong>espeak</strong> uses the PortAudio sound library (version 18), so you will need to have the <strong>libportaudio0</strong> library package installed.  It may be already, since it's used by other software, such as OpenOffice.org and the Audacity sound editor.<p>
+<strong>espeak-ng</strong> uses the PortAudio sound library (version 18), so you will need to have the <strong>libportaudio0</strong> library package installed.  It may be already, since it's used by other software, such as OpenOffice.org and the Audacity sound editor.<p>
 Some Linux distrubitions (eg. SuSe 10) have version 19 of PortAudio which has a slightly different API. The speak program can be compiled to use version 19 of PortAudio by copying the file portaudio19.h to portaudio.h before compiling.<p>
  The speak program may be compiled without using PortAudio, by removing the line<pre>   #define USE_PORTAUDIO
 </pre>in the file speech.h. 
 The installer: <strong>setup_espeak.exe</strong> installs the SAPI5 version of eSpeak.
 During installation you need to specify which voices you want to appear in SAPI5 voice menus.
 <p>
-It also installs a command line program <strong>espeak</strong> in the espeak program directory.
+It also installs a command line program <strong>espeak-ng</strong> in the espeak-ng program directory.

 <h2>2.2 COMMAND OPTIONS</h2>
 <hr>
 <h3>2.2.1 Examples</h3>
 To use at the command line, type:<br>
- &nbsp; <strong>espeak "This is a test"</strong><br>
+ &nbsp; <strong>espeak-ng "This is a test"</strong><br>
 or<br>
- &nbsp; <strong>espeak -f &lt;text file&gt;</strong>
+ &nbsp; <strong>espeak-ng -f &lt;text file&gt;</strong>
 <p>
 Or just type<br>
- &nbsp; <strong>espeak</strong><br>
+ &nbsp; <strong>espeak-ng</strong><br>
 followed by text on subsequent lines. Each line is spoken when
 RETURN is pressed.
 <p>
-Use <strong>espeak -x</strong> to see the corresponding phoneme codes.
+Use <strong>espeak-ng -x</strong> to see the corresponding phoneme codes.

 <h3>2.2.2 The Command Line Options</h3>
 <dl>
 <dt>
-<strong>espeak [options] ["text words"]</strong><br>
+<strong>espeak-ng [options] ["text words"]</strong><br>
 <dd>Text input can be taken either from a file, from a string in the command, or from stdin.
 <p>
 <dt>
 <dt>
 <strong>-v &lt;voice filename&gt;[+&lt;variant&gt;]</strong><br>
 <dd>Sets a Voice for the speech, usually to select a language. eg:
-<pre>   espeak -vaf</pre>
+<pre>   espeak-ng -vaf</pre>
 To use the Afrikaans voice.  A modifier after the voice name can be used to vary the tone of the voice, eg:
-<pre>   espeak -vaf+3</pre>
+<pre>   espeak-ng -vaf+3</pre>
 The variants are <code> +m1  +m2  +m3  +m4  +m5  +m6  +m7</code> for male voices and <code> +f1 +f2 +f3 +f4 </code> which simulate female voices by using higher pitches. Other variants include <code>+croak</code> and <code>+whisper</code>.
 <p>
 &lt;voice filename&gt; is a file within the <code>espeak-data/voices</code> directory.<br>
 <p>
 <dt><b>Phoneme Input</b>
 <dd>
-As well as plain text, phoneme mnemonics can be used in the text input to <strong>espeak</strong>.  They are enclosed within double square brackets.  Spaces are used to separate words and all stressed syllables must be marked explicitly.<p>
- &nbsp; eg: &nbsp; <code> espeak -v en "[[D,Is Iz sVm f@n'EtIk t'Ekst 'InpUt]]" </code><p>
+As well as plain text, phoneme mnemonics can be used in the text input to <strong>espeak-ng</strong>.  They are enclosed within double square brackets.  Spaces are used to separate words and all stressed syllables must be marked explicitly.<p>
+ &nbsp; eg: &nbsp; <code> espeak-ng -v en "[[D,Is Iz sVm f@n'EtIk t'Ekst 'InpUt]]" </code><p>
  This command will speak: "This is some phonetic text input".
 </dl>
 

docs/languages.html

 A number of Voice files are provided in the <code>espeak-data/voices</code> directory.
 You can select one of these with the <strong>-v &lt;voice filename&gt;</strong> parameter to the
 speak command, eg:
-<pre>   espeak -vaf</pre>
+<pre>   espeak-ng -vaf</pre>
 to speak using the Afrikaans voice.<p>Language voices generally start with the 2 letter <a href="http://en.wikipedia.org/wiki/ISO_639-1">ISO 639-1 code</a> for the language.  If the language does not have an ISO 639-1 code, then the 3 letter <a href="http://www.sil.org/iso639-3/codes.asp">ISO 639-3 code</a> can be used.
 <p>
 For details of the voice files see <a href="voices.html">Voices</a>.
 Alternatively there are some preset voice variants which can be applied to any of the language voices, by appending <code>+</code> and a variant name. Their effects are defined by files in <code>espeak-data/voices/!v</code>.
 <p>
 The variants are <code> +m1  +m2  +m3  +m4  +m5 +m6 +m7</code> for male voices, <code> +f1 +f2 +f3 +f4 +f5 </code> for female voices, and <code> +croak  +whisper</code> for other effects. For example:
-<pre>   espeak -ven+m3</pre>
+<pre>   espeak-ng -ven+m3</pre>
 The available voice variants can be listed with:<br>
-<pre>   espeak --voices=variant</pre>
+<pre>   espeak-ng --voices=variant</pre>

 <p>
 <li>If you use the eSpeak voice such as "<b>mb-en1</b>" then eSpeak will use the mbrola "en1" voice, eg:<br>
-<code>espeak -v mb-en1 "Hello world"
+<code>espeak-ng -v mb-en1 "Hello world"
 </code>
 <p><p>
 To generate mbrola phoneme data (.pho file) you can use:<br>
-<code>espeak -v mb-en1 -q --pho "Hello world"</code>
+<code>espeak-ng -v mb-en1 -q --pho "Hello world"</code>
 <br>or<br>
-<code>espeak -v mb-en1 -q --pho --phonout=out.pho "Hello world"</code>
+<code>espeak-ng -v mb-en1 -q --pho --phonout=out.pho "Hello world"</code>

 The phoneme mnemonics are based on the scheme by Kirshenbaum which represents International Phonetic Alphabet symbols using ascii characters.  See: <a href="http://www.kirshenbaum.net/IPA/ascii-ipa.pdf">www.kirshenbaum.net/IPA/ascii-ipa.pdf</a>.

-Phoneme mnemonics can be used directly in the text input to <strong>espeak</strong>.  They are enclosed within double square brackets.  Spaces are used to separate words, and all stressed syllables must be marked explicitly. eg:<br>

 A Voice file specifies a language (and possibly a language variant or dialect) together with various attributes that affect the characteristics of the voice quality and how the language is spoken.<p>
 Voice files are placed in the <code>espeak-data/voices</code> directory, or within subdirectories in there.<p>
 The available voice files can be listed by:<pre>
-   espeak --voices
+   espeak-ng --voices
 or
-   espeak --voices=&lt;language&gt;</pre>
+   espeak-ng --voices=&lt;language&gt;</pre>
 also
-<pre>   espeak --voices=&lt;variant&gt;</pre>
+<pre>   espeak-ng --voices=&lt;variant&gt;</pre>
 Lists voice variants which can be applied to eSpeak voices.
-<pre>   espeak --voices=&lt;mbrola&gt;</pre>
+<pre>   espeak-ng --voices=&lt;mbrola&gt;</pre>
