[Freeswitch-users] Detect events other than DTMF during .streamFile

Hi I was wondering if it was possible to detect events other than DTMF that are fired during .streamFile?. DTMF events are received by my callback without issue, but if I try to use speech detection via mod_pocketsphinx the callback doesn't get fired. If this is not possible, are there any other options available to me in order to detect speech input during the playback of a file? Kind Regards jdee
