WP4: Conclusion

Work on training independent task is in progress, and the use of generalized phone models has resulted in considerable improvements in recognition accuracy. The work on automatic segmentation of broadcast news has produced promising results, enabling both the overall error rate and computational cost to be reduced. This is important work both because it represents a real-world problem, and because CUED are committed to participate in DARPA broadcast news CSR evaluations. Inital work on frequency warping for speaker adaptation has produced encouraging results, and it is planned to extend this technique to broadcast news.
