چکیده

We present a 1000-word continuous speech recognition (CSR) system that operates in real time on a personal computer (PC). The system, designed for large vocabulary natural language tasks, makes use of phonetic Hidden Markov models (HMM) and incorporates acoustic, phonetic, and linguistic sources of knowledge to achieve high recognition performance. We describe the various components of this system. We also present our strategy for achieving real time recognition on the PC. Using a 486based PC with a 29K-based add-on board, the recognizer has been timed at 1.1 times real time.

Progress Report for DARPA SLS Program at DRAGON Systems, Inc

Dragon Systems has continued to develop its continuous speech recognition capability on personal computers, with a strong focus on achieving real-time or near real-time performance in that environment We are now able to run recognition using vocabularies of up to 5000 words, although the larger vocabularies do slow down the recognition substantially; therefore more work still needs to be done t...

Speech Recognition Software and Vidispine

To evaluate libraries for continuous speech recognition, a test based on TED-talk videos was created. The different speech recognition libraries PocketSphinx, Dragon NaturallySpeaking and Microsoft Speech API were part of the evaluation. From the words that the libraries recognized, Word Error Rate (WER) was calculated and the results show that Microsoft SAPI performed worst with a WER of 60.8%...

Real Time Implementation of a License Plate Location Recognition System Based on Adaptive Morphology

License plate recognition (LPR) by using morphology has the advantage of resistance to brightness changes; high speed processing, and low complexity. However these approaches are sensitive to the distance of the plate from the camera and imaging angle. Various assumptions reported in other works might be unrealistic and cause major problems in practical experiences. In this paper we considered ...

Research in Continuous Speech Recognition at Dragon Systems Under the DARPA SLS Program

The primary long term goal of the speech research at Dragon Systems is to develop algorithms that allow us to achieve high performance large vocabulary continuous speech recognition. At the same time, we are concerned to keep the computational demands of our algorithms as modest as possible, so that the results of our research can be incorporated into products that will run on modestly priced p...

Improved Bayesian Training for Context-Dependent Modeling in Continuous Persian Speech Recognition

Context-dependent modeling is a widely used technique for better phone modeling in continuous speech recognition. While different types of context-dependent models have been used, triphones have been known as the most effective ones. In this paper, a Maximum a Posteriori (MAP) estimation approach has been used to estimate the parameters of the untied triphone model set used in data-driven clust...
