Still stumped on trying to write a streamlined pocketsphinx speech
recognition. I went through SpeechTools.jm and I think I pulled out
the necessary pieces, but the speech event is not being fired. I get
dtmf events if I push a key, but not speech. I must be missing a
piece, but I have stared at SpeechTools.jm until I can't see straight.
Here is my code:
function onInput(s, type, inputEvent, _this) {
console_log("debug", "EVENT:" + type + "\n");
}
session.answer();
var blankobj = new Object();
var rv;
var hit;
var dup;
var grammar_name="pizza_yesno";
var collected_index=0;
var req=1;
var obj_path="result";
var halt=true;
var min_score=20;
var confirm_score=10;
console_log('INFO', "Setting grammar\n");
session.execute("detect_speech", "nogrammar " + grammar_name);
session.execute("detect_speech", "pocketsphinx " + grammar_name);
session.execute("detect_speech", "resume");
console_log('INFO', "entering while loop\n");
session.streamFile( "audiofile.wav", onInput, "blankobj") ;
while(session.ready() && collected_index < req) {
var x;
if (!rv) {
rv = session.collectInput(onInput, "blankobj", 500);
if (rv && !rv[0]) {
rv = false;
}
}
if (!rv) {
session.execute("detect_speech", "resume");
rv = session.collectInput(onInput, "blankobj", 5000);
}
hit = false;
if (rv) {
var items = rv;
rv = undefined;
for (y = 0; y < items.length; y++) {
console_log("debug", "---- "+items[y]+"\n");
}
}
if (!rv) {
rv = session.collectInput(onInput, "blankobj", 1000);
}
}
