日本电视新闻节目的字幕播放需求十分强烈。然而，由于日语使用表意文字，新闻节目的字幕稿件的键盘输入无法跟上语速。为了实现日语新闻节目的同步字幕，开发了一个实时语音识别系统来处理广播新闻的转录。实验结果表明，该系统对播音员语音的实时识别错误率为2.8%，通过人工校正，平均总延迟为10.4 s，错误率可降至0.8%。
There are strong demands to expand captioned broadcasting for TV news programs in Japan. However, keyboard entry of captioned manuscripts for news programs cannot keep pace with the speed of speech because Japanese use ideographic characters. To realize simultaneous subtitling of Japanese news programs, a real-time speech recognition system to handle broadcast news transcription has been developed. Experiments showed that word recognition error rate of the system for studio announcer speech is 2.8% in the real-time recognition and the error rate can reduce to 0.8% by manual correction with an average total delay of 10.4 seconds.
