Experiments can be hosted on the Department of Linguistics server, and then distributed to listeners by email link, or via Amazon Mechanical Turk.
An example is here: example experiment
A Javascript library audexp.js that makes it realatively easy to implement the following four kinds of typical experiment:
- Identification - a single audio file is played, and a two-alternative forced choice (2AFC) is given.
- Discrimination - two audio files are played, and a 2AFC is given.
- Rating - a single audio file is played, and a rating number (from 1 to 7) is given.
- Contrast Rating - two audio files are played, and a rating number is given.
Your html code must have three features:
- source a javascript file that defines
-- an array (or two arrays) of filenames that will be presented. -- a variable called 'block' -- here's an example of such a file -- this .js file was created with a small perl script from a .csv spreadsheet.
-- the html header contains these two lines to get the audexp.js library and the experiment-specific
<script src="js/blocktest_list.js"></script>
<body onload="load('id',false,500,2000);">
