New approaches for domain transformation and parameter combination for improved accuracy in parallel model combination (PMC) techniques.

New approaches for domain transformation and parameter combination for improved accuracy in parallel model combination (PMC) techniques.

Parallel model combination (PMC) techniques have been very successful and popularly used in many applications to improve the performance of speech recognition systems under noisy environments. However, it is believed that some assumptions and approximations made in this approach, primarily in the do...
