本文介绍了在P502 EURESCOM项目框架内开发的多语种系统。所描述的系统以五种语言提供关于在英国、德国、法国、意大利和葡萄牙可用的主要电话服务的信息。我们提出了一些在五个国家进行的实验的结果，旨在尝试和回答一些基本的问题与开发的多语言服务。技术和接口设计问题进行了调查，并测试了几种替代方案。我们比较了GSM和PSTN网络的语音识别准确率和成功交易完成率，并评估了跨国家和跨语言的影响。使用一种新的评估方法，开发了一个强大的预测模型。该模型允许用户的主观评级从客观测量预测。结果表明，当语音识别器表现出良好的单词识别准确率耦合到合适的对话界面，在平均交易成功率超过92%。IVR系统。(C)2000由Elsevier Science B.V.出版，保留所有权利。
The paper describes the multilingual system developed within the framework of the P502 EURESCOM project. The system described provides information about major telephone services available in the UK, Germany, France, Italy and Portugal in five languages. We present the results of a number of experiments carried out in the five countries, aiming to try and answer some fundamental questions concerned with the exploitation of a multilingual service. Both technological and interface design issues have been investigated and several alternatives have been tested. We compared speech recognition accuracy and successful transaction completion rates of GSM and PSTN networks, and evaluated crosscountry and cross-language effects. Using a new methodological approach to assessment, a powerful predictive model was developed. This model allowed users' subjective ratings to be predicted from objective measurements. The results showed that an average Transaction Success rate of more than 92% was obtained when speech recognisers exhibiting good Word Recognition Accuracy were coupled to suitable dialogue interfaces in. the IVR system.
