Thanks for letting us know - we've realised we were unclear with our initial correction: the modal that asks for mic permission and explains that all audio processing is done in-browser now only appears when 'Record' is pressed, so users can check out the rest of the website.
The website only works in Chrome or Opera at the moment - this may be what is causing you problems. Potentially yes - we are starting with Mandarin because it's such a popular language to learn. What other languages would you like to see?
Hi, thanks for bringing that to our attention. We will work on it. We would like to work towards giving people feedback on whole sentences. We plan to work on 2-syllable words first.
Hi, yes the classifier needs some improving. We expect that it would be much more difficult to make an accurate classifier for Cantonese, although we could make a website which presents Cantonese words/phrases and lets you see your (and the teacher's) pitch contour. Would that be of interest?
Hi, yes unfortunately at the moment the classifier can be quite inaccurate sometimes, especially if your microphone is catching some background noise. We will work on improving this.
Thanks for the feedback! We didn't realise this would pose such a problem. We've updated the website so it asks for microphone permission after people press the 'Record' button.
Helping mandarin learners practice the tones in their own time without the need for a private tutor to correct them. Record yourself speaking in-browser, and get instant feedback: pitch contour and what tone that sounded like.
Any feedback welcome!
