The SmartVR Module is an easy-to-use and cost effective voice/speech recognition development platform, based on Sensory's RSC-4128 mixed signal processor, for developing speech synthesis and voice recognition applications. Its small size (42mm x 72mm) and two 28-pin connectors with 2.54mm pin spacing, make it breadboard friendly and suitable for prototype boards.

The SmartVR Module is capable of running the latest Sensory's FluentChip™ core technology libraries which offer:

• Speaker Dependent Recognition (works with eny language but requires user training).
• Speaker Independent Recognition (do not require user training) available in the following laguages:
  • US English
  • UK English
  • German
  • French
  • Italian
  • LA Spanish
  • Japanese
  • Korean
• Speech.
• DTMF Synthesis.
• Speaker Verification.
• Record and Play.
