iSTI Lite measures the Speech Transmission Index (STI) according to IEC 60268-16 2nd edition (1998). It is a fully functional STI measuring tool, but does not offer all the advanced features of iSTI Professional or iSTI Standard. iSTI Lite is useful for casual speech intelligibility testing by home or business users.
