New:  SPATS Speech Perception Assessment and Training Systems!

• SPATS-HI: Speech testing and training for hearing-impaired persons.
  
• SPATS-ESL: Speech testing and training for those learning English as a second language

Both systems have been shown to improve the ability to understand conversational English spoken at normal rates.
