Abstract:

Analyzing the impact of normalization method applied in isolated word speech dominant and noise characteristics to discover the continuous speech characteristic curve adjustment problems. The authors raised optimized solutions to further solve the problem of instability and unpredictability of the noise characteristics for voice effects. Robust continuous speech recognition model by normalization method in this paper can achieve a clean environment in the laboratory and real noise environment so as to get the best recognition results.

Key words: normalization, noiserobust, continuous speech recognition
