A link is presented to the browser:
echo "<embed src=\"http://sites.mydomain.com/cgi-bin/play.cgi?speech+1\"
autostart=\"true\" hidden=\"true\" width=\"0\" height=\"0\">"
echo "</embed>"
The browser requests the URL, and the server executes the CGI and sends
the following:
echo "Content-Type: audio/x-wav"
echo "Content-transfer-encoding: BINARY"
echo
espeak --stdout "This is a test and only a test"
The espeak program does a text-to-speech conversion and outputs a WAV
stream. I can output the audio to a file and then serve the file, but
the results are the same.
Safari on a Mac plays the stream. Safari (and Firefox) on Windows XP
plays nothing!
This is the header for the response received by the browser:
HTTP/1.x 200 OK
Date: Thu, 23 Oct 2008 20:32:16 GMT
Server: Apache/2.2.0 (Fedora)
Content-Transfer-Encoding: BINARY
