|
<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>

<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>
