ASTi has integrated Speech Recognition (SR) into our Telestra 4 product suite. The result is a one-box solution integrating SR with simulation models. Compare this solution with a mix of different vendor equipment providing core communications simulation and SR and you'll inevitably find a spider's web of analog cable runs.

ASTi is able to leverage the power of the ACENet audio distribution architecture to support SR installations requiring high SR seat counts by passing the incoming audio over the Ethernet-based network in the digital domain to a Target.

The ASTi SR solution features the following:

• Speaker independent (no training required)
• Continuous recognition (phrases and sentences are both understood)
• Background noise robustness
• Dynamic grammar switching
• Multi-channel support
• Recognition success rates in the high 90's percentile
• Multiple grammar formats available to simplify grammar specification

Depending on the application, ASTi SR technology is configurable for word-by-word recognition for system control or sentence-based recognition for use in “natural language” applications such as radio communications. Potential applications include:

• Instructor workstation voice control
• Cockpit systems voice control
• Automated Air Traffic Control and radio environment simulation
• Talk-on target systems
