Проверьте ответ с помощью Speech To Text

Question

Есть ли способ проверить ответ, используя голос в текст? Я уже сделал голосовую часть текста. Например, ответ - яблоко. И я уже получаю слово «яблоко» с помощью распознавания голоса. То, что я хочу сделать, это сравнить мой ответ (голос) и истинный ответ (яблоко), то же самое, нужно некоторое руководство.
