Hi! I'm Nik, a solo founder, and I make TonePerfect.
You record a word or a sentence and get a score for every word and every sound, so you hear exactly which sound gives your accent away.
- 8 courses: English, Mandarin Chinese, Spanish, French, German, Russian, Japanese and Korean
- Mandarin: each syllable's tone is scored separately from its initial and final
- Japanese is scored on sounds only (pitch accent is not scored)
- Free browser accent check, no signup: https://toneperfect.app/accent-check
- Free tools: Mandarin tones test (https://toneperfect.app/mandarin-tones-test) and a pinyin chart with audio (https://toneperfect.app/pinyin-chart)
- Apps: iOS, Android and web (https://toneperfect.app/learn). Free tier with daily limits, Premium subscription.
For developers there is a pronunciation API (https://api.toneperfect.app): 10 languages, experimental, scripted speech, 50 free credits without a card.
