<description>
<para>Selects and plays the proper singular or plural form of a noun
when saying things such as "five calls". English has simple rules
for deciding when to say "call" and when to say "calls", but other
languages have complicated rules which would be extremely difficult
to implement in the Asterisk dialplan language.</para>
<para>The correct sound file is selected by examining the
<replaceable>number</replaceable> and adding the appropriate suffix
to <replaceable>filename</replaceable>. If the channel language is
English, then the suffix will be either empty or "s". If the channel
language is Russian or some other Slavic language, then the suffix
will be empty for nominative, "x1" for genative singular, and "x2"
for genative plural.</para>
<para>Note that combining <replaceable>filename</replaceable> with
a suffix will not necessarily produce a correctly spelled plural
form. For example, SayCountedNoun(2,man) will play the sound file
"mans" rather than "men". This behavior is intentional. Since the
file name is never seen by the end user, there is no need to
implement complicated spelling rules. We simply record the word
"men" in the sound file named "mans".</para>

<description>
<para>Selects and plays the proper form of an adjective according to
the gender and of the noun which it modifies and the number of
objects named by the noun-verb combination which have been counted.
Used when saying things such as "5 new messages". The various
singular and plural forms of the adjective are selected by adding
suffixes to <replaceable>filename</replaceable>.</para>
<para>If the channel language is English, then no suffix will ever
be added (since, in English, adjectives are not declined). If the
channel language is Russian or some other slavic language, then the
suffix will the specified <replaceable>gender</replaceable> for
nominative, and "x" for genative plural. (The genative singular is
not used when counting things.) For example, SayCountedAdj(1,new,f)
will play sound file "newa" (containing the word "novaya"), but
SayCountedAdj(5,new,f) will play sound file "newx" (containing the
word "novikh").</para>
