SeeSay and HearSay CAPTCHA for mobile interaction
Sajad Shirali-Shahreza, Gerald Penn, Ravin Balakrishnan, Yashar Ganjali

Speech certainly has advantages as an input modality for smartphone applications, especially in scenarios where using touch or keyboard entry is difficult, on increasingly miniaturized devices where useable keyboards are difficult to accommodate, or in scenarios where only small amounts of text need to be input, such as when entering SMS texts or responding to a CAPTCHA challenge. In this paper, we propose two new alternative ways to design CAPTCHAs in which the user says the answer instead of typing it with (a) output stimuli provided visually (SeeSay) or (b) auditorily (HearSay).
