A good syllable counter on the Internet is Wordcalc. When text is pasted into the entry box, Wordcalc provides the number of syllables in the word. Wordcalc is useful for counting words, characters, the average number of syllables per word and the average number of characters per word.
Another website, How Many Syllables, offers five methods for counting syllables without the use of an online counter. The five methods are the Listen Method, the Chin Method, the Clap Method, the Robot Speak Method and the Written Method. How Many Syllables also offers lessons on dividing words into syllables, common grammar mistakes and correct punctuation.
