Some Experiments in Evaluating ASR Systems Applied to Multimedia Retrieval
نویسندگان
چکیده
This paper describes some tests performed on different types of voice/audio input applying three commercial speech recognition tools. Three multimedia retrieval scenarios are considered: a question answering system, an automatic transcription of audio from video files and a real-time captioning system used in the classroom for deaf students. A software tool, RET (Recognition Evaluation Tool), has been developed to test the output of commercial ASR systems.

Improving Multimedia Retrieval with a Video OCR
We present a set of experiments with a video OCR system (VOCR) tailored for video information retrieval and establish its importance in multimedia search in general and for some specific queries in particular. The system, inspired by an existing work on text detection and recognition in images, has been developed using techniques involving detailed analysis of video frames producing candidate t...
متن کاملReducing Retrieval Time in Automated Storage and Retrieval System with a Gravitational Conveyor Based on Multi-Agent Systems
The main objective of this study is to reduce the retrieval time of a list of products by choosing the best combination of storage and retrieval rules at any time. This is why we start by implementing some storage rules in an Automated Storage/Retrieval System (Automated Storage and Retrieval System: AS/RS) fitted with a gravity conveyor while some of these rules are dedicated to storage and ot...
متن کاملEmpirical Studies in Multimedia Retrieval Evaluation
The evaluation of retrieval mechanisms for inter-method comparison is necessary in academic as well as in applied research. A major issue in every evaluation is in which way and to what extent the actual perception of the user from the target user group is integrated. Within multimedia retrieval systems the impressions and perceptions of users vary much more than in text retrieval. Empirical st...
متن کاملAn Integrated Dialog Simulation Technique for Evaluating Spoken Dialog Systems
This paper proposes a novel integrated dialog simulation technique for evaluating spoken dialog systems. Many techniques for simulating users and errors have been proposed for use in improving and evaluating spoken dialog systems, but most of them are not easily applied to various dialog systems or domains because some are limited to specific domains or others require heuristic rules. In this p...
متن کاملDevelopment of a Speech Recognition System for Spanish Broadcast News
One of the ASR applications is the generation of transcripts to facilitate searching through multi-media collections containing spoken data. Especially in the broadcast news domain ASR systems have been successfully deployed to index large collections of news. First of all because retrieval performed on ASR generated transcripts with an word-error rate (WER) under 50% gives resonable results [1...
