Abstract
We investigate techniques for acoustic modeling in automaticrecognition of context-independent phoneme strings from the TIMITdatabase. The baseline phoneme recognizer is based on TempoRAl Patterns(TRAP). This recognizer is simplified to shorten processing times andreduce computational requirements. More states per phoneme and bi-gramlanguage models are incorporated into the system and evaluated. Thequestion of insufficient amount of training data is discussed and thesystem is improved. All modifications lead to a faster system withabout 23.6% relative improvement over the baseline in phoneme errorrate.
