Abstract: This paper describes a command-based robust speech recognition system for the Portuguese language. Due to an efficient noise reduction algorithm the system can be operated in adverse noise environments such as in cars or factories. The recognizer was trained and tested with a speech database with 250 commands spoken by 345 speakers in clean and noisy conditions. The system incorporates a user friendly application programming interface and was optimized for embedded platforms with limited computational resources. Performance tests for the recognizer are presented.
