Error while installing Ubuntu 12.04

[jitendra8911]

Hi All....I am having windows 7 on my machine.I am trying to install Ubuntu in my machine.I burned Ubuntu 12.04 .iso image to a DVD.I was able to boot successfully from the DVD.I am getting error "speech dispatcher disabled " immediately after I choose to install Ubuntu.I checked MD5 of the .iso image I downloaded.It is fine.I also checked if there are any errors on the disk from which I am booting.They were no errors.Please can any one help me where it is going wrong .
