Wakeword

Custom word or phrase recognition solution that activates dormant devices or activities using kids’ voices.

Voice Search

We enable voice search for kids –
Our technology returns confidence scores for each search term to activate searches.

Voice Control

Replacing the need for complex buttons, controllers and menus, we enable kids to voice control their online or offline games, toys and characters.

Speech To Text/Transcription

Text transcription of an audio file of kids’ speech – words, phrases or sentences – with analysis down to the phoneme level.

Conversation/Dialogue

We enable scaffolded dialogue to power conversations between kids and their favorite offline and digital characters.

Reading Practice

Real-time, detailed feedback of pronunciation of phonics, words, phrases and short sentences, down to the phoneme level.

Keyword Spotting

Our technology analyzes whether a given target e.g. words/phrases/commands/search terms etc. in an audio file were spotted in isolation or in a sentence or in background noise.

Fluency Assessment

For mature readers.
Our technology analyzes kids’ reading fluency and returns metrics such as number of correct words, words correct per minute (WCPM), insertions, deletions and substitutions.

Voice Activity Detection (VAD)

The ability to detect when a child begins to speak. VAD enables technology to begin processing, recording or analysing only when a child’s voice is detected.

Pronunciation Assessment

Real-time, detailed assessments of a child’s pronunciation of phonics, words, phrases and short sentences, down to the phoneme level.

Comprehension Questions

Real-time assessments of kids’ oral responses to reading comprehension questions.

Multiple Choice Questions

Real-time scoring of kids’ oral responses to text or speech based multiple choice questions.

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”
