This paper proposes an efficient speech sample selection technique that can identify those samples that will be well recognized. Conventional confidence measures can identify well-recognized speech samples, but they require speech recognition to estimate confidence scores. Speech samples with low confidence should not undergo recognition since they yield speech documents that will eventually be rejected...
This paper proposes an efficient combination of state likelihood recycling and batch state likelihood calculation for accelerating acoustic likelihood calculation in an HMM-based speech recognizer. Recycling and batch calculation are each based on different technical approaches, i.e. the former is a purely algorithmic technique while the latter fully exploits PC architecture, and their good acceleration...
In this paper, the method of 3D transient analysis of the ultrasonic propagation in flow field is developed using the finite difference time domain method. In this method, in order to take account of flow field, the semi-Lagrange coordinate system, in which physical quantities are defined by the Euler coordinate system and the time derivative term is discretized by the Lagrange coordinate system,...
