Problem with festival tts in php

[daisycmyk]

Im having a problem with embedding/executing 'text2wave'  command inside php script. 

I want to read one text file (in this case text1.txt)  , covert it into (wav/mp3) format and play that file. (automatically on page load or on form button click)

Im using somewhat modified version of php script located here  http://www.xenocafe.com/tutorials/php/festival_text_to_speech/index.php

 

My code snippet

<?php 
if(isset($response)){
  //echo $response;
    echo "<br/>"; 
     // if(!empty($response)){   
            $wave_file='test1.wav';
            $speech_file='test1.txt';
            $volume_scale=50;
            
            $fh = fopen($speech_file, "w+");
                
                if ($fh) {
                    fwrite($fh, $response);
                    fclose($fh);
                }
       if (file_exists($speech_file)) {
      // create the text2wave command and execute it
[b]        $cmd = "text2wave $speech_file -o $wave_file";[/b]
        echo $cmd;
[b]        exec($cmd);[/b]  // this is not working 
        echo exec('date');// this is working 
       //unlink($wave_file);
        }
        
    echo '<embed height="19" width="185" src="test1.wav" visibility="true"></embed>';}
  }

 

Sorry about this scrappy code , im not very good at php .. yet.

exec($cmd) part is not working , text1.wav file is not being generated(which it must)

Does  it has to with ENVIRONMENTAL VARIABLES or PATH?

But $text2wave $speech_file -o $wave_file from shell is working without a problem.

 

Thanks in advance.Any help would be greatly appreciated.
