Desafio global de trava-línguas para aquecer a voz Leia em voz alta, receba precisão real e bata seu recorde
Step 1: Choose a language and tongue twister
Pick a language set and a real local tongue twister. Mature SpeechRecognition languages enable true speech scoring.
吃葡萄不吐葡萄皮，不吃葡萄倒吐葡萄皮。
先慢慢分清「葡萄」與「皮」，再追求速度。
Step 2: Record aloud or use timer mode
After you start, your browser may ask for microphone access. Speech recognition runs through the native Web Speech API; this page calculates text similarity and time locally.
Practice tips and privacy
Start slowly and clearly, then increase speed. Tongue twisters reward clarity and control, not speed alone.
If the page shows timer mode, the browser or language cannot provide reliable speech recognition, so no fake score is displayed.
Personal bests are stored only in localStorage on this device and disappear when browser data is cleared.
O que é o desafio global de trava-línguas?
Transforma trava-línguas reais em jogo de navegador e, quando há suporte, usa a Web Speech API para medir transcrição, precisão e tempo. Learn the background of tongue twisters, the browser Web Speech API, and the SpeechRecognition interface.
True scoring, not just a stopwatch
Serve para aquecer a voz de apresentadores, professores, podcasters, atores e estudantes de idiomas. In supported languages, the tool compares the recognized transcript with the target phrase using edit-distance similarity, then combines accuracy and elapsed time into a score.
Honest fallback when speech recognition is unavailable
If the selected language or browser is not reliable for SpeechRecognition, the page clearly switches to timer-only mode and says there is no speech score. You can still warm up, self-rate, and save the fastest local time.
