Voice Recognition: is possible in PHP or not?
<p>I am developing a website in PHP for illiterate people, to teach language alphabetically.
At the end I'll create an assessment phase in which learners have to speak aloud through microphone the shown alphabet letter. When the learner pronounces the word I want to compare it with the saved alphabetic pronunciation.</p>

<p>Is it possible to do voice comparison with PHP?</p>
