Problems using SAPI with PHP through COM, on IIS -


i attempting text speech , speech recognition work in php using microsoft's sapi through com objects.

in past, used code tts work (apache 2.1, php 5.5, on windows 2003 server)

// instantiate object $voiceobj = new com("sapi.spvoice") or die("unable instantiate sapi");  // available voices $voicestoken=$voiceobj->getvoices(); $numberofvoices=$voicestoken->count; for($i=0;$i<$numberofvoices;$i++) {  $voicetoken=$voicestoken->item($i);    $voicename[$i]=$voicetoken->getdescription(); }  // , print id of specified voice $selectedvoicetoken=$voicestoken->item(0); $selectedvoicetokenid=$selectedvoicetoken->id;  // set voice $voiceobj->voice=$selectedvoicetoken; $voicename=$voiceobj->voice->getdescription();  $voicefile = new com("sapi.spfilestream");  $voicefile->open('./test.wav', 3, false);   // speak file $voiceobj->audiooutputstream = $voicefile; $voiceobj->speak("what unbelievable test", 0); $voicefile->close();

on new setup (iis 7.5, php 7.0, windows server 2008r2) same code fails at

$voiceobj->speak("what unbelievable test", 0);  fatal error: uncaught com_exception: <b>source:</b> unknown<br/><b>description:</b> unknown in \\web\tts.php:30 stack trace: #0 \\web\tts.php(30): com->speak('this marve...', 0) #1 {main}

with such little detail (where retrieve more?) can't figure out problem may be.

writing permissions checked. php 7.0 replaced 5.5, still not working. same code tested win32 app, , works flawlessly.

any hints?
