Our World Class Voice Technology

SoapBox Labs proprietary voice technology is supported by our large database of kids speech, and delivers best-in-class accuracy across global accents and dialects.

Our voice technology works in the real world, noisy environments kids inhabit. No need for headsets and mics.

The power behind our technology is its accuracy. Regular assessments for accuracy show that our results agree with those of human annotators – linguists and teachers – 95% of the time. 

We offer a globally scalable online API, and offline SDK, with embedded solutions coming soon.


Demo: Phonemic Breakdown

SoapBox Labs voice technology returns percentage based scores for target phrases, words, sentences, paragraphs and for every speech sound in the target phrase. Accurate scoring is delivered, right down to the phoneme level.
To see how it works, choose a sentence and press play.

“SoapBox Labs generally performs best, likely due to the fact that its models are specifically designed to work on children’s speech”
