Speech
Translator

Speech translator is a device that helps people with hearing disability to
understand conversations. It works as a real-time subtitle, which translate
speeches to a symbolic language.

Raspberry Pi

This project is based on Raspberry Pi to build prototypes

The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote teaching of basic computer science in schools

A translator that uses a new language
Benefits of using
symbolic languages
Not sound based

For people who can’t hear, words make less sense to
them because without pronunciation, words are just
combination of letters. Compared to recognizing the
shape of one word, pattern has more visual elements
to identify. The brain is good at processing images data.

High recognizability

The disadvantage of existing written language is that the
recognizability is not good when the font size is small.
Symbolic language works like logos which can be recognized
even from far distance. This feature makes it perfect in this
case that the words will be mostly read only.

Easier to remember

Image information is processed by the right half of our
brains, which helps remembering much faster compared
to thinking logically with the left brain.

This project is about finding possible solutions for certain user, instead of testing the reliability of the conceptual language, thus
The context is set up in
a parallel universe
In-class User Testing
Setup for the user testing
For the user testing, there are information about the project shown on the laptop,
the user wears the headset which plays white noise to emulate hearing disabilities.
The user follows the instructions and learn how to use the translator.
