I wrote a sample form page with a simple math problem to solve -- 2 or
3 random small integers to add and put the result in a form field

def produce_expression():
    """
    return a tuple: expression (str), answer (int)
    """
    num_terms = random.randint(2,3)
    operands = []
    while num_terms:
        n = random.randint(1,21)
        operands.append(n)
        num_terms -= 1

    result = sum(operands)
    string_operands = map(str, operands)
    expression = " + ".join(string_operands)
    return expression, result

Its not as annoying as captcha and I think it would work with audio
browsers.  Never tested
