Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Adaptive training is an important approach to training speech recognition systems on found, non-homogeneous data. The standard approach employs a single transform to represent unwanted acoustic variability. Hover, for found data there are commonly multiple acoustic factors affecting the speech signal. The paper investigates the use of multiple forms of transformations, structured transforms (ST), to represent the complex non-speech variabilities in an adaptive training framework. Two forms of transformation are considered, cluster mean interpolation and constrained MLLR; consequently, the canonical model here is a multi-cluster HMM model. Both ML and minimum phone error (MPE) reestimation formulae for the canonical model, are presented. This multi-cluster MPE training is also applicable to eigenvoice systems. Experiments to compare ST to standard adaptive training schemes re performed on a conversational telephone speech task. ST re found to reduce the word error rate significantly.
