I am not sure if this is a PHP bug or my inexperience with MS SAPI 5.1, but I saw a similiar problem (ID 15205) that was not resolved. I am using PHP 4.3/Apache 2.0.43/W2K and I can not set the Voice property with an object variable. 

THE CODE:

// This instantiates the object
$VoiceObj = new COM("SAPI.SpVoice") or die("Unable to instantiate SAPI");

// Gets the available voices and prints them
$VoicesToken=$VoiceObj->GetVoices();
$NumberofVoices=$VoicesToken->Count;
For ($i=0;$i<$NumberofVoices;$i++)
{
   $VoiceToken=$VoicesToken->Item($i);
  $VoiceName[$i]=$VoiceToken->GetDescription();
  print "$VoiceName[$i]................Item Number: $i </br>";
}

// Gets and prints the id of the specified voice
$SelectedVoiceToken=$VoicesToken->Item(1);
$SelectedVoiceTokenid=$SelectedVoiceToken->id;
print "$SelectedVoiceTokenid</br>";

// Tries to SET the voice (but fails)
$VoiceObj->Voice=$SelectedVoiceToken;
$VoiceName=$VoiceObj->Voice->GetDescription();
print "$VoiceName</br>";

// This changes the rate of the selected voice
$VoiceObj->Rate = "0";

$VoiceObj->Speak("Hello, welcome to my website");

unset($VoiceObj);

THE RESULTS:
