ASR-based CALL
ASR-based CALL
CALL Computer Aided Language Learning
the search for and study of applications of the
computer in language teaching and learning

ASR Automatic Speech Recognition

• The effectiveness of speech-interactive CALL
• is determined less by the capabilities of the
• speech recognizer than by
• the design of the language learning activity and
  feedback
• b) the inclusion of repair strategies to
  safeguard against recognizer error.

PARLING Test
GOALS

• System content
• - to study which activities children prefer
• - to verify voice interaction use
• - to verify personalization
• 2. Usability and accessibility
• 3. Speech material collection

Interaction TASKS
3 sessions 30 minutes each User freely roams
through PARLING Questionnaires at the end
