LTG, It's not so much Hal's fault as it is the TTS voice(s) that are being used.
Each company assigns their own way in which a particular voice pronounces a word or phrase.
One of my voices says LOL as if saying LULL...yet a different one says "Laughing Out Loud" when it encountered the LOL.
Microsoft, VoiceWare's & CereProc say, "L.O.L., that was funny." (they pronounce each Letter individually).
ScanSoft says, "Lull, that was funny."
Ivona says, "Laughing Out Loud, that was funny."
Your own mileage might vary....
