example.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz

I recorded the sound using Cepstral. This is my AGI 
I thought maybe was my sound card but this works fine
$AGI->say_number('9865');
$AGI->say_digits('873746');
and I can hear it in my SIP phone

use Asterisk::AGI;
use File::Basename;
use Digest::MD5 qw(md5_hex);
 
 
 $AGI = new Asterisk::AGI;
 %input = $AGI->ReadParse();
 #
$AGI->say_number('9865');
$AGI->say_digits('873746');
 
speak("Hello World....");
 
 
 
sub speak
  {
    $text = $_[0];
 
    my $hash = md5_hex($text);
 
    my $ttsdir = "/var/lib/asterisk/sounds/tts";
    my $cepoptions = "-p audio/sampling-rate=8000,audio/channels=1";
 
    my $wavefile = "$ttsdir/tts-$hash.wav";
 
    unless (-f $wavefile)
      {
        open(fileOUT, ">/var/lib/asterisk/sounds/tts/say-text-$hash.txt");
        print fileOUT "$text";
        close(fileOUT);
 
        my $execf="/opt/swift/bin/swift -f $ttsdir/say-text-$hash.txt -o $wavefile $cepoptions";
        system($execf);
 
        unlink("$ttsdir/say-text-$hash.txt");
      }
    $filename = 'tts/'.basename('tts/'.basename($wavefile,".wav"));
    $AGI->stream_file($filename);
#  unlink("$wavefile");
