Abstract (in Japanese) (See Japanese page) 
(in English) We developed an ambient system that plays a music suitable for the mood of a human-human conversation
using words obtained from a continuous speech recognition system.
Using the correspondent between a document space based on the texts related to the musics and
an acoustic space that express various audio features,
the continuous speech recognition results are mapped to an acoustic space.
Proper names, which are not coverd by the continuous speech recognizer,
are recognized by a wordspotter.

In this paper, we show the result of the perfomance evaluation for the system.
For read music review texts, the system obtained in MRR of 0.83, which is not bad, with high WER of 70.55\%, not low F measure of 31.58.
We also show an example result for chat conversations.
