+

+
+   For example suppose that the following message is supplied to espeak_Synth:
+   "hello, hello."
+
+
+   * Once processed in RETRIEVAL mode, it could lead to 3 calls of the callback function :

+
+   ** SENTENCE
+   ** WORD (call when the sounds are actually played)
+   ** WORD
+   ** END (call when the end of sentence is actually played.)
+   ** MSG_TERMINATED
+
+
+   The MSG_TERMINATED event is the last event. It can inform the calling program to clear the user data related to the message.
+   So if the synthesis must be stopped, the callback function is called for each pending message with the MSG_TERMINATED event.
+
+   A MARK event indicates a <mark> element in the text.
+   A PLAY event indicates an <audio> element in the text, for which the calling program should play the named sound file.
