In this talk, I’ll report on our expe­ri­ences mov­ing speech per­cep­tion exper­i­ments from the lab­o­ra­to­ry to online test­ing envi­ron­ment, high­light­ing our suc­cess in repli­cat­ing many stan­dard speech per­cep­tion par­a­digms (e.g., cat­e­gor­i­cal per­cep­tion, lex­i­cal­ly guid­ed per­cep­tu­al learn­ing, dis­tri­b­u­tion­al learn­ing, talk­er nor­mal­iza­tion, per­cep­tu­al learn­ing of noise-vocod­ed speech) using online protocols.

Along the way, I’ll describe some chal­lenges we’ve encoun­tered (e.g., head­phone com­pli­ance, low-effort par­tic­i­pants, vari­abil­i­ty in response times) and the ways in which we’ve attempt­ed to mit­i­gate these challenges.
