Summary on Grant Application Form |

We propose to gather a multispeaker articulatory/acoustic speech database (British version of TIMIT) suitable for training a state-of-the-art ASR system. The articulatory data will be captured directly and simultaneously with the acoustic recording using a purpose built studio which incorporates an Electromagnetic Articulograph, an Electropalatograph and Larybogoraph. Parameters derived from the articulatory data will be used as input features to a standard triphone model, mixture density HMM recogniser and the word error rate on a multispeaker recognition task compared with that of the same system using traditional acoustic features. Once an articulatory feature set has been determined which demonstrates an improved recognition score, a supervised learning process will be employed so that the articulatory parameters may be estimated from the acoustic signal. This nonlinear transform of the acoustic data into a feature space that is atuned to the dynamic constraints imposed by human speech production should lead to a recogniser that is more robust in its ability to handle inter and intra speaker variability.
