Does your speaking voice sound too robotic?

Perhaps you should vary both your pitch and speaking rate. Yesterday at Computerworld there was a brief, humorous Shark Tank article titled To stop speaking to a real person, press 0. It said:

“The call center for this college's IT help desk has one particular staffer who's really, really good at his job, reports a pilot fish in the loop.

‘He's calm, professional and succinct,’ fish says. ‘So much so, in fact, that one caller took him for a voice-response system and demanded to speak to a ‘real person.’
 
‘The caller would not accept the staffer's word that he was, in fact, a real person.'
 
'He continued to demand to speak to a real person until the staffer transferred the caller to his supervisor.’ “
