Pronunciation Helper is a pronunciation checker that uses the GOP HMM-DNN algorithm. This website is built on Django.

How to Use

1. Input your text
2. Record yourself
3. Submit
4. Review pronunciation scores by hovering over words

Tips for accurate scoring

• Submit your recordings sentence by sentence
• Speak clearly and at a natural pace
• Ensure your environment is not too noisy

Notes

• This tool does not replace feedback from English speakers!
• The symbols that appear when you hover over words (e.g. AH, IH, etc.) are ARPABET phonemes.
• The scores indicate how closely the spoken phoneme matches the expected pronunciation.

Future Improvements

• More accurate scoring can be achieved by using a nnet3 model instead of a chain model (source)
