Description

Great public speakers are made, not born. Quantle estimates the number of syllables and words you say, computes the length of pauses you make, estimates your pitch and voice volume. The app development is inspired by the need to estimate talk effectiveness by a digital coach in a fair, repeatable, and unbiased way. Quantle works for languages in which the number of syllables in a word is determined by the number of vowels (e.g., English, German, Russian), although we tuned Quantle mainly for English.

The smartphone running Quantle should be placed within a few meters from the speaker. Quantle uses an adaptive online algorithm to compute talk estimates. It does not work with background music and other disturbing sounds. By default, it neither stores the audio stream nor communicates any of its parts. We used a collection of 1k+ TED talks to tune algorithm performance. Quantle achieves 90% accurate syllable and word counting on average. Pitch estimation is based on the Fast Lifting Wavelet Transform (FLWT).
