We appreciate, if you would send us some of photos of the WAVE workshop you shot. We will add then to the collection of snap shots. Thank you in advance for your help.

Wakayama workshop on Auditory and Vocal rEsearch

A specialized workshop on auditory aspects of speech perception and production will be held on the 10th and 11th April 2004. We hope to provide a comfortable setting for discussion between interested researchers in order to create and merge ideas towards a better understanding of this exciting and emerging research field. This can only be achieved by your time and participation in this workshop.

Organizer: Hideki Kawahara (Wakayama University, Japan)

Scope and format

Introduction of a very high-quality speech analysis/modification/synthesis method STRAIGHT and a new auditory computational theory based on stabilized wavelet-Mellin transform has opened up interesting research questions on the basis of our auditory and speech perception. This workshop is intended to disseminate our ideas and to induce discussions on how to approach these questions. Important topics to be discussed are on vowel normalization and temporal dynamics of speech. This workshop is also an extension to our previous workshops under CREST's Auditory Brain Project and our special session in ICA 2004 .

The workshop is currently scheduled to start at 13:30 on 10th April and completes discussions at 12:00 on 11th April. This will allow plenty of time for discussions and extra personal activities after the workshop.

A resort accommodation called "Futago shima soh" (Twin Islands Villa), which is located next to a famous viewing park "Banndoko Teien" (Lookout Garden) , is reserved for isolation and concentration with some excursions.


Going to the venue:
A limited express "Super Kuroshio" leaves from JR Kyoto station at 9:34 AM and bound for Wakayama JR station. (Expected arrival time is 11:01.) A hotel shuttle bus will depart from EAST gate (The primary gate is west. EAST gate is the smaller one.) of JR Wakayama station at 12:30. (Please take a lunch at Wakayama station.)

Please note that the departing time from JR Kyoto station was changed from 10:32 to 9:34. Don't miss it.
Most of invited speakers are expected to get on the same train.

Leaving from the venue:

Information about the venue, Futagojima- So, and the reimbursement of expenses

  1. Futagojima-So is a traditional Japanese Inn
    - All the guest rooms are Japanese style, and each room is shared by 2-3 person. (usually shared by 4 person)
    -We'll make room assignment according to your request, smoking or non-smoking.
  2. Both of breakfast and dinner are Japanese dishes. In case if you have allergies to any particular foodstuffs or have any particular request, please let us know by the end of March.
  3. The room rate will be around 15000 yen including breakfast and dinner. Please settle the bill either by cash in Japanese yen or credit card. VISA and Master cards are acceptable.
  4. Please also settle the bill by yourself for the rest of any other accommodations we booked.
  5. Although we try to finish the necessary paperwork for the reimbursement, it still takes long time. Your travel expenses will be paid most probably after returning home. We will let you know the method of payment when we got information from the accounting Dept. in Wakayama university. We apologize for the inconvenience.

About us and the workshop

Wakayama University established its Faculty of Systems Engineering on October 1995. A group of researchers working in auditory, speech and vision research fields were recruited from ATR, NTT, Kyoto University, Nagoya University and NAIST to form a COE project to lead its research and development activities. This workshop is one of the projects' activities expected to be held on a regular basis. For this first occasion, the acronym "WAVE" stands for "Wakayama workshop on Auditory and Vocal rEsearch". Depending on the topic, the name of the workshop can change. We are quite flexible in accepting your suggestions for topics of coming workshops. (This workshop is sponsored by Wakayama University.)
