BotDetect Audio CAPTCHA Samples
BotDetect CAPTCHA provides an audio Captcha alternative to assure human verification is accessible to the blind and other visually impaired people. BotDetect is developed with the Access Board Section 508 guidelines in mind, and produces XHTML 1.1 and WCAG AAA compliant markup.
By default, BotDetect audio Captcha uses Html5
<audio> elements for sound playback. It also detects browsers that don't support Html5 Wav audio fully or properly, and automatically falls back to using
<object> elements instead. This ensures such browsers can still play audio Captcha and remain as accessible as they were before Html5 audio was introduced.
Audio CAPTCHA Sound Security
BotDetect audio Captcha functionality uses 20 different sound styles, each style using an unique combination of effects and noises. This makes audio Captcha much more resistant to any automated audio analysis, especially when the sound style used for each generated audio Captcha is picked randomly.
Multi-language Audio CAPTCHA Pronunciations
BotDetect CAPTCHA offers a variety of different audio Captcha localized pronunciations. Each localized audio Captcha pronunciation is recorded by a native speaking voice-over artist in a professional recording studio, which guarantees the best quality of sounds used for generation of the audio Captcha alternative.
To allow maximum flexibility in choosing locale support that suits your needs, sound resources have been separated from the main component into external language-dependent sound packages. These can be downloaded separately from the BotDetect localizations page when you need them.
Here is a sample selection of some popular audio Captcha localizations:
You can find all currently supported localized audio Captcha pronuciations on BotDetect localizations page.
