The AASP Technical Committee runs a series of ‘Challenges’ in order to encourage research and development with comparable and repeatable results, and to stimulate new ground-breaking approaches to specific problems in the AASP technical scope. This activity is coordinated by the Challenges Subcommittee listed below.
Call for Challenges
Proposals to organize an AASP Challenge are invited. This is an open call with no deadline. Please email a Stage 1 - Statement of Interest (see below) to the Challenges subcommittee chair (firstname.lastname@example.org).
- Stage 1 - Statement of Interest
- Stage 2 - Full Proposal
- a textual description of the challenge and its context (1 to 2 pages);
- a clear formulation of the problem to be addressed;
- a specification of the evaluation methodology leading to an objective figure of merit (FoM) and, where appropriate, a software tool to compute the FoM;
- a development dataset which represents the challenge and which will be made public (a public training dataset may also be needed in some challenges);
- a test dataset which also represents the challenge but which will remain private during the challenge;
- a commitment to provide a website to disseminate the challenge itself and, eventually, the results;
- a commitment to evaluate the submitted results and publish the comparison on the website and elsewhere as appropriate;
- a proposed schedule for the challenge (date of publication of the challenge, deadline of results submission, deadline of comparative results publication).
To propose to organise a Challenge, please send a statement of interest in about 2 pages outlining the aim of the challenge and its value to the community, giving also a preliminary perspective of the practical elements including the planned test data and evaluation methodology.
If supported by the Subcommittee, a full proposal would be invited. The full proposal should include the following items:
Please send the Statement of Interest and the Full Proposal to the AASP Challenges Subcommittee chair at the address below. All proposals will be considered by the Challenges Subcommittee. The Subcommittee may request modifications to the challenge as a condition of acceptance.
Researchers entering the challenge are invited to sign up at the challenge website. Participants will address the challenge specification and employ the evaluation methodology and the development dataset to develop their algorithm. Participation is open to all.
At the end of the challenge, the organizers will coordinate a comparative evaluation employing the defined FoM. Evaluation may be done for example by releasing the test dataset and asking the participants to return their results on the test data within a short period of time, typically two weeks. Participants would be honour-bound not to use the test dataset for tuning.
The evaluation results will then be published by the organizers. The Challenges Subcommittee will work with the challenge organizers towards publication of the challenge and its outcome in the IEEE Transactions and appropriate conferences, ICASSP in particular. In addition, the challenge organizers’ website will be linked from the TC webpage. Participants can choose to remain anonymous in publications.

IEEE AASP CHALLENGES 2014
Call for Participation:
Several established parameters and metrics have been used to characterize the acoustics of a room. The most important are the Direct-To-Reverberant Ratio (DRR), the Reverberation Time (T60) and the reflection coefficient. The acoustic characteristics of a room based on such parameters can be used to predict the quality and intelligibility of speech signals in that room. Recently, several important methods in speech enhancement and speech recognition have been developed that show an increase in performance compared to the predecessors but do require knowledge of one or more fundamental acoustical parameters such as the T60. Traditionally, these parameters have been estimated using carefully measured Acoustic Impulse Responses (AIRs). However, in most applications it is not practical or even possible to measure the acoustic impulse response. Consequently, there has been a growing research activity in the estimation of such parameters directly from speech and audio signals.
ACE Challenge Overview
The ACE Challenge is part of the programme of Challenges organised by the IEEE Audio and Acoustic Signal Processing Technical Committee http://www.signalprocessingsociety.org/technical-committees/list/audio-tc/.
The aim of this challenge is to evaluate state-of-the-art algorithms for blind acoustic parameter estimation from speech and to promote the emerging area of research in this field. Participants will evaluate their algorithms for T60 and DRR estimation against the ‘ground truth’ values provided with the data-sets. Furthermore, they are expected to present the results in a paper describing the method used.
Full details can be found at www.ace-challenge.org
Data: A data-set specifically designed for the challenge tasks will be provided. This will include speech from male and female talkers in different sized rooms and different noise conditions for a single microphone and for microphone arrays with three (mobile), five (cruciform), eight (linear), and thirty-two (spherical) microphones
Task 1: Single-microphone T60 and DRR estimation
Task 2: Multi-microphone T60 and DRR estimation
Evaluation: The evaluation metrics will be based on the ground truth values. This will consist of full-band and 1/3-octave band values for T60 and full-band values for the DRR
ACE Challenge Schedule
Please see www.ace-challenge.org for the key dates of the ACE Challenge.
ACE Challenge Workshop
The challenge participants will be invited to present their results at the ACE Challenge workshop, which is planned to be held as a satellite event in conjunction with WASPAA 2015 in New Paltz, NY, USA

IEEE AASP CHALLENGES 2013
Call for Participation:
Recently, substantial progress has been made in the field of reverberant speech signal processing, including both single- and multi-channel de-reverberation techniques, and automatic speech recognition (ASR) techniques robust to reverberation. To evaluate state-of-the-art algorithms and draw new insights regarding potential future research directions, we call for participation in the REVERB (REverberant Voice Enhancement and Recognition Benchmark) challenge that will provide an opportunity to the researchers in the field to carry out comprehensive evaluation of their methods based on a common database and evaluation metrics. The challenge aims at bringing together researchers from a broad range of disciplines to discuss novel and established approaches to handle reverberant speech. This challenge is part of the IEEE SPS AASP challenge series. The following is an outline description of the challenge.
REVERB Challenge Overview
Data: Real and simulated 1-, 2-, and 8-channel recordings in reverberant meeting rooms based on the Wall Street Journal Corpus. This data is common for the following 2 tasks*.
Task 1: Enhancement of reverberant speech with single-/multi-channel de-reverberation techniques
(Evaluation metrics: objective and subjective measures)
Task 2: Robust recognition of reverberant speech
(Evaluation metric: word error rate)
* Participants are invited to take part in either or both of the above tasks.

IEEE AASP CHALLENGES 2012
Detection and Classification of Acoustic Scenes and Events
Call for Participation:
On behalf of the IEEE AASP Technical Committee, I am happy to announce a new challenge entitled: "Detection and Classification of Acoustic Scenes and Events". The challenge has the form of a public contest for the evaluation of the performance of systems for the detection and classification of acoustic events and audio scenes.
The challenge includes a set of tasks for the detection and classification of acoustic scenes and events and its goal is to provide a focus of attention for the scientific community in developing systems for computational auditory scene analysis (CASA) that will encourage sharing of ideas and improve the state of the art, potentially leading to the development of systems that achieve performance closer to that of humans.
This challenge will help the research community move forward by providing a focus for better defining the specific tasks, and will also provide incentive for researchers to actively pursue research on this field. Finally, it will offer a reference point for future systems developed to perform similar tasks and it will provide the community with a high quality database for future research.
There will be a discussion phase where potential participants are invited to contribute their ideas, ending on 30th September 2012. The deadline for code submission is 31st March 2013. Results will be presented at a special session in WASPAA 2013 (http://www.waspaa.com/); participants are invited to present a poster at a special session. Also, authors of novel work are encouraged to submit their work as a regular paper at WASPAA 2013.
