Digital Speech Processing

Since 1975, ARCON Corp. has been actively involved in digital speech communications technology ranging from signal compression and packet-switched voice communications to secure digital voice communications. This work has been conducted in two major areas. The first is research and development on low-rate digital voice coders operating in high acoustic noise environments. The second is the subjective evaluation of the performance of digital voice communication systems. As a result of ARCON's extensive experience with both military and commercial systems, ARCON enjoys a position on the forefront of secure communications technology which is playing an increasingly significant role in all types of voice communications.

ARCON is involved in the following activities:

• Acoustic Noise Environment Characterization & Simulation
• Generation of Test Material for Voice Communication Systems
• Acoustic & Non-Acoustic Transducer Characterization
• Transmission Channel Characterization & Simulation
• Test Bed Development & System Evaluation
• Host Laboratory Functions
• Subjective Evaluations of Voice Communication Systems
• Multi-Sensor Speech Science
