A rule based system for speech verification
نویسندگان
چکیده
A rule based system for speech verification is proposed as a feedback mechanism for speech recognition. The system provides an explicit way ofselecting verification parameters depending on the item to be recognized and its context. An extended continuous logic is used to combine the evidence from different parameters and an automatic way to convert parameter values to logic evidence values is given. From the parameter evaluation and through the combination of logical values, an information weight is propagated to account for parameter extraction errors and poorly trained data.

Design and Implementation of an Intelligent Part of Speech Generator
The aim of this paper is to report on an attempt to design and implement an intelligent system capable of generating the correct part of speech for a given sentence while the sentence is totally new to the system and not stored in any database available to the system. It follows the same steps a normal individual does to provide the correct parts of speech using a natural language processor. It...

Biometric system based on unimodel biometrics are not able to meet the desired performance requirements for security purpose due to problems such as intra-class variations, noisy data, unacceptable error rates and low performance. Multimodal biometrics refers to the use of two or more biometrics modalities in a single identification system. The combination of different modalities is used to imp...
متن کاملMultimodal Person Verification from Video Sequences
In this paper, a multimodal person verification system based on fusing information derived from face and speech signals is proposed. Principle component analysis and independent component analysis techniques are used for face verification and melfrequency-cepstral coefficients are used for speaker verification. The matching scores from individual modalities are combined using the sum rule. The ...
متن کاملNovel Applications of Neural Networks in Speech Technology Systems: Search Space Reduction and Prosodic Modeling
Neural networks (NNs) have been extensively used in speech technology systems. In this paper, we present two novel applications of NNs in speech recognition and text-to-speech systems. In very large vocabulary speech recognition systems using the hypothesis-verification paradigm, the verification stage is usually the most time consuming. State of the art systems combine fixed size hypothesized ...
