It is possible for eSpeak's voice parameters such as volume, pitch, rate, language etc to change if NVDA reads text containing eithe controlA (u+0001) characters, or raw less-than and greater-than commands. Filtering out of controlA chracters at least was fixed in NVDA 2009.1 #437 but then regressed in 2011.2 when espeak synthDriver's speakText method was replaced with a speak method. Simply, the resulting string after translating the bad characters was dropped rather than reassigned back to the string for speaking.
