1. Conferences
1.1 IEEE
I joined the SLTC (Speech and Language Technical Committee) of theIEEE Signal Processing Society from 2010, and a member of the review committee of the international conference, ICASSP, from 2009.
1.2 INTERSPEECH
Three research papers were presented at “INTERSPEECH”, an international conference on speech communication, which was held in Brighton, England [2009_09, 2009_10, 2009_11]. I also engaged in the reviewing process as a member of the Scientific Review Committee. The conference had set up the “Public Exhibition” booth this year, in which I demonstrated the vocal-tract models. Professor Roger Moore (University of Sheffield), the chair of this year’s conference, had asked me at the previous year’s conference in Brisbane, to participate and to make a demonstration. Our plan was realized, and I was able to demonstrate the vocal-tract models at the conference, and also to Mayor Brighton & Hove. The footage of the demonstration was shown at the Opening Ceremony of the conference as well.
I also visited two universities before and after the conference. I paid my first visit to the University College London, and looked around the laboratories, and gave the talk “A replication of Chiba and Kajiyama’s mechanical models of the human vocal-tract and their application for education in speech science” in the Speech Science Forum. I was also able to meet Professor Stuart Rosen and Professor Peter Howell, the authors of the book “Signals and Systems for Speech and Hearing” that I supervised and took a part in its translation to Japanese, and discussed about the publication of its second edition. I also visited the University of Cambridge and was able to meet Professor Patterson (Professor Irino had also been paying a visit at that time). I had a chance to demonstrate the vocal-tract models, and looked around the campus.
