We do not speak the way we write, so why should we write our speeches when we could just speak them? LEXICON is a dictation app for smart devices where the user can write their speech in the most intuitive way, by speaking it aloud.


People are more scared of giving a presentation or speech than they are of dying.


Using technology to break the barrier in a person's mind that stops them from practicing for presentations.


Give them the tools they need to make it easier and more comfortable to practice their presentation.

User Journey

Style Guide

The name Lexicon comes from the greek word λεξικόν, which means "of or for words". Our app Lexicon is meant to help users become more comfortable presenting with their own language, vocabulary, and knowledge.

We chose the butterfly as our logo, because we all get butterflies in our stomach when we are nervous, Lexicon helps you set those butterflies free.

Lexicon Mobile Application

MAIN SCREEN: Dictate whatever you want right from the home page, just press the red record button.
VIDEO SCREEN: Video record your practices, this helps with pinpointing body mannerisms used while presenting.
SPEECH CORRECTION: Grammar check for speech, showcases filler words, pitch, and hesitations.
NOTEPAD: This is where the dictated recordings get saved. Edit your practices, or write down notes while you are practicing.

Speech Grammar Check

Spoken grammar is different from written grammar. LEXICON has grammar check for speech which listens to pitch, filler words, hesitations, and allows you to find replacement words. After dictating your speech, LEXICON then speech grammar checks it so that you can see what your speech sounds like.

Physical Product Extension

A bluetooth wearable microphone that pins to the users shirt. It is paired with the LEXICON app to make dictating on your phone easier and less awkward.
